CONTINUATION OF TRYON'S MONOGRAPH OF THE HELICID.E, BY H. A. PILSBRY. Group X, PENTATJENIA, A. Schmidt. Shell globose or somewhat depressed, of moderate or large size, imperforate or moderately umbilicate, usually with five revolving bands ; animal provided with a dart ; jaw moderately arched, and, except in AHognatlms, with strong separated ribs, usually few in number, and grouped on its median portion ; the central teeth have a strong middle cusp ; the side cusps are usually obsolete ; the lat- erals are similar, but asymmetrical ; the marginal teeth have several short cusps. I follow Kobelt in grouping the following subgenera under the general head of Pentatseuia. The number of bands in nearly every species of the group is normally five, but frequently is less, through coalescence or absence of bands. This pentateeniate character will separate the group from the preceding, Arionta, which has one or three bands, and from Rhaguda Xeropliila, etc., which have numerous bands. The group is European in distribution, and comprises the largest and most characteristic helices of that region.- HELIX. 121 Section I, TACHEA Leach, 1820.

Island of Habibas, off Algiers. HELIX. 141 In addition to Bourguignat's figures of this form, I give those of Kobelt, (PI. 61 figs.13-15.) According to the latter author, the species is not found upon the island of Rachgoun, but at Nemours. There is also some difference between the two authors as to the concholog- ical characters of the species, Kobelt's form being less striate above, and measuring 26 mill, in diam., 17 in alt. H. PSEUDOEMBIA Debeaux. PI. 42, figs. 58, 59.

Diam. 32, alt. 21 mill. Leila Mar ma, Morocco, between Nemours and Tlemcen. Allied, according to Kobelt, to H. zaffarina. Its relation to H. embia seems quite as close, and with that species it forms the transi- tion to " die Gruppe der Doppel-Zahner," as Kobelt calls the follow- ing species. Most of these are probably merely local races ; for like many of the northern African shells the characters upon which the species are founded, such as texture, development of mouth parts, etc., are endlessly variable ; every locality, with its slightly differing soil and climate producing a new and correspondingly differing race of mollusk.

This group of large Helices is intermediate in conchological characters between Macularia and Leptaxis, and rather closely allied to both. In distribution it is restricted to the Canary Archipelago, no species being found outside the limits of that group ; and it is the most prominent form of Helix in the mollusk fauna of those islands, occupying them to the exclusion of Iberus, Leptaxis and (almost) of Macularia. Several species very similar to recent forms are found fossil in central European mioceue deposits, associated with Macularia, Clausilia, Melanopsis, etc. There is a similarity between some species of Hemicycla (such as H. malleata) and certain West Indian forms of Deutellaria, (H. obesa, H. dentiens) ; this resemblance is more likely to be due to con- vergence of type, caused by similar environments than to any close relation or connection between these specialized forms ; and the same may be safely said of the superficial likeness which the African Macu- laria jobaeana bears to the West Indian Dentellaria formosa, etc. The species of Hemicycla are very numerous, and frequently sep- arated by characters so slight as to render it very likely that the number of species bonce would be considerably reduced by a critical study of the intermediate forms and the variations produced by peculiarities of station, hypsometical distribution, etc. Such a study however, we are not likely to have as long as the great majority of land-shell specialists pursue the intensely analytical methods now in voo-ue. III'LIX. 151 In the treatment of the species I have generally followed Jules Mabille, whose paper, "Materiaux pour une fauna malacoloyique des iles Canaries" is the most recent and complete publication on the subject. A number of descriptions have been taken from Mousson, and from Wollaston. H. PLICARIA Lamarck, 1816. PL 49, figs. 51, 52. Imperforate, depressed, solid, opaque, corneous brown, lighter below, unicolored, or with very obscure darker bands above, about three in number, and sometimes a fourth just below the periphery ; obliquely costate with elevated separated coarse ribs ; frequently split or slightly interrupted upon the periphery, and which are crenulated by very numerous dense fine spiral impressed lines, which scarcely or not at all cut the surface between the ribs ; whorls 4, moderately convex, regularly increasing, the apex nearly smooth, large, obtuse, first two whorls much smoother than balance of shell, body-whorl obtusely subangular at its beginning, becoming rounded and rather tumid and gibbous below as it approaches its termination, abruptly, deeply deflexed and deeply constricted behind the aper- ture ; aperture very oblique, contracted, small, irregularly oval; peristome white, very broadly, flatly expanded, its terminations some- what converging, joined by a thin callus; basal margin thickened within by a slightly tortuous lamellar denticle, appressed over the umbilical region, which is but slightly or not at all indented. Diam. 22, alt. 14 mill. Ins. Teneriffe, Canaries. H. plicatula Lam., H. orbiculata Wood, H. planorbula Gray are synonymous.

Allied to H. glasiana and H.fritschi; from the former its greater size, the elevation of its conical spire, and the thicker, more oblique peristome distinguish it; from the latter, the curved base (straight in H.fritschi}, and different armature of same, separate the present species.

I am not satisfied with the synonymy of the consobrina group ; for I believe that several of the following forms are merely varieties of that species. It is impossible however, to work the species out with the meagre material before me. A var. vetnsta Mouss., is more depressed, suture less impressed, last whorl subangulate, and aperture smaller than the type. H. EVKKdAsTA Mabille, 1882. PL 48, figs. 100, 101.

Differs from H. consobrina in the more compact coiling of the whorls, the last one simply rounded, not inflated ; the peristome is slightly thickened, flat, angular at the junction of the columellar and outer margins, not reflexed and callous as in H. consobrina. H. BATHYCLERA Mabille, 1885. PI. 49, figs. 23-25.

Specimens of this form before me are thinner and of lighter text- ure than H. consobrina. They are frequently unicolored ; and the peristome is not (generally) so heavy ; its upper margin is highly arched, subangular ; and the whole shell is finely granulose, as in the allied species. H.

Imperforate, depressed subglobose, striatulate, irregularly mal- leate, obsoletely microscopically granulate, very bright, brownish yellow, with four or five brown bands, streaked and maculated with yellow; spire obtusely convex, regular; apex minute, brownish purple, smooth; sutures simple, subimpressed, whorls 4J, rather rapidly in- creasing, slightly convex, the last large, descending, rounded, inflated, slightly constricted, below lighter colored, and slightly impressed in the center; aperture oblique, subample, transversely irregularly oval ; peristome acute, moderately reflexed, thickened within, margins subconverging, the upper subsinuately incurved, basal margin slightly curved, nearly straight, thickened, at the insertion, adnate. Diam. 21, alt. 12 mill. Ins. Teneriffe, Canaries. The original description is translated above. Of this species Wollaston says : "I cannot feel absolutely satisfied that it is more in reality than a smaller and ungranulated race of the consobrina, in which the transverse lines of growth are a trifle less evident and the malleations a little more so, and in which the surface is altogether HELIX. 175 more glossy and shining, and the color of a more uniform ochreo- olivaceous brown speckled with small irregular angulated blotches and fragmentary reticulations of yellow. It is generally smaller than the H. consobrina. H. MAUGEAXA Shuttleworth, 1852. PL 50, fig. 94; PI. 48, figs. 14-16. Imperforate, depressed-globose, in young shells very thin and transparent, in adults solid, yellowish brown or brownish yellow, not shining, lightly striate and irregularly reticulate-malleate, under the lens densely finely granulate, four or five fasciate, the bands sometimes interrupted, the second and third frequently coalescent ; spire conic, apex minute, purplish, shining, minutely rugose ; suture distinct; whorls 42-5, the last rapidly increasing, large, rounded tumid, toward the aperture somewhat gibbous, slightly constricted ; base rather convex, slightly impressed in the centre ; aperture oblique, lunate, oblong-oval, margins subparallel, subapproximating ; peristome slightly thickened, reflexed, violet tinted, basal margin adnate, thickened within, whitish. Diam. 20, alt. 11 mill. Environs of Saint Croix, Ins. Teneriffe, Canaries. It is H. gaudryi of Reeve, and, in part, of Pfeiffer. There has been some doubt as to the precise form described by Shuttleworth, and the confusion is increased by the fact that he assigns no habitat nearer than " Canaries " in his description. I have accepted Mabille's identification. The species is quite variable in the development of the bands, and the intensity of the color. H. DISTENSA Mousson, 1872. PI. 50, figs. 89, 90.

Diam. 16J, alt. 11* mill. Ins. Gomera, Canaries. Of this little-known form Mabille says: A species intermediate between H. guamartemea and H. perraudieri. It is much more globular than the latter; its whorls, particularly the last are inflated ; the ornamentation consists of a nearly effaced malleation, with traces of granulation visible only under a strong lens.

Diam. 19 mill. "Llanos" af the Banda, West side of Ins. Palma, Canaries. Described from immature examples. Wollaston says: "I feel almost confident that the character of 'semiobtecta perforata' will be found to hold good during all periods of growth ; and such being the case, its affinities, which at first sight are not readily apparent will perhaps be ascertained to lie amongst the forms around the H. planorbella, though, at the same time, the species has evidently something in common with the (equally Palmau) H. granomalleata. Not to mention this peculiarity of the umbilicus, the present species is smaller than H. granomalleata, and it is also rather more depress- ed both abpve and below, and it has a fine thread-like though minute keel which is traceable even down to the very aperture. It is not much malleated, its sculpture consisting mainly (apart from the excessively minute sand-like granules) of extremely irregular and HELIX. 179 densely-packed, coarse, subconfluent oblique ridges, or subundulating vermiform folds; and in color it would seem to be of a dingy oliva- ceous-white, suffused with a darker tint in consequence of the four or five obsolete bands which are indistinctly indicated." Mabille considers this form a variety or monstrosity of H. planor- bella. H. AMBLASMODON Mabille, 1883. PI. 48, figs. 17, 18.

Section VII. LEPTAXIS Lowe, 1852. Leptaxis inhabits the more outlying Atlantic islands, Madeira, the Azores and the Cape Verdes. There is considerable diversity of form among the species ; and this has caused a part of them to be considered as belonging to Hemicycla, (a group restricted to the Canary Is.) and the remainder to be divided into several subsections, three of which I retain for convenience in identifying specimen >.

This species has been confounded by some authors with H. embes- cens, but is most readily separated by attention to the sculpture and the character of the columella, which has a wholly different in- sertion from that species. The spiral sculpture, is shared with the following species; but in advena is so obscure as to be easily over- looked. The species never has so warm a color as H. erubescens. IIKI.IX. II.

Diam. 17, alt, 14 mill." Fogo and Brava, Cape Verde Is, The following quotation from Wollaston may aid in the identifi- cation of the present, species, which I have never seen. "In its rather globose outline, dull hue, and uninterrupted bands, this Helix has somewhat the prima fastie aspect of the (nevertheless totally dissimilar) Porto-Sanctan H. punctulata Sow.; though in reality it belongs to an altogether different group. It is indeed closely allied to the II. visgeriana, as is evident, not merely from its ^eneral plan of coloring and from its umbilicus not being com- pletely closed over, but likewise from the presence of the minute spiral lines which (under a high magnifying power) are everywhere visible on its surface. Specifically however, it is quite distinct, it being not only larger and more globose, and of a uniformly duller tint, but likewise with the minute spiral lines (which look more like indistinct subundnlating scratches) more irregular and obscure, and with the oblique transverse costie well-nigh obsolete, and (such as they are) concolorous with the rest of the surface, the entire shell appearing comparatively smooth and unsculptured. Its umbilicus too, is a little less closed over, and its suture is very deeply im- pressed." H. VISGERIAXA Dohrn, 1867. PL 66, fig. 80c. Covered perforate or nearly so, globose depressed, shining, corne- ous, with four or five narrow dark brown bands of which two are below the periphery, and which are frequently interrupted by reg- ular strong oblique whitish stris? ; revolving impressed lines visible chiefly in the interstices of the stria?; whorls 3 ', slightly convex. 13 194 HELIX. rapidly increasing, the last rounded, slightly descending anteriorly ; aperture rounded lunar, oblique ; columella well curved, expanded over the umbilicus.

Nevertheless, it is thicker, whiter and more calcareous ; its peristome has nearly always a faint rosy tinge (indeed the entire shell is often suffused with a faint rosy brown); its volutions, the lia-al one of which is not quite so perceptibly keeled, are a trifle more tumid, and the suture consequently somewhat more impressed ; its columella is just appreciably straighter, forming somewhat of an angle at its junction with the lower lip ; and its entire surface has a tendency to be irregularly blotched, or freckled, with very obscure paler, frequently confluent patches."

Helices of the section I her us are very numerous, both in species and individuals in central and southern Italy, and in Sicily ; and curiously enough, there have been a few trans-Mediterranean spe- cies discovered in recent years. Then- is great lattitude of opinion concerning the synonymy of the group, arising from the fact that transition forms between many of the " species " render any hard- and-fast lines of demarkation between them wholly arbitrary; and the subject has been still further complicated by a number of diag- noses of" new species," without figures, each of which admits of be- ing applied to several forms. The Sicilian species form a perfect series of gradations between the carinate flattened forms and the globose elevated ones. They -'02 HELIX. differ from most of the peninsular species in being marked with minute spiral impressed lines. The Italian species are generally more depressed, and more deeply colored. Montfort's type of Iberus is not H. muralis as I stated on p. 122 (following Albers and v. Martens) but H. gualteriana of Spain. There may be two subsections recognized : Iberus, s. sir. and Levan- litin. Kobelt, the latter comprising the large forms of Asia Minor. The synonymy includes Murella Pfr., and, in part, Crenea Albers. Pfeiffer and other authors have included, also, a number of Canary Island species, which in this work are placed in Hemicyda.

" Some specimens exhibit a small umbilical fissure, but in the greater number this is closed by the expansion of the columellar margin. A very minute spiral striation is visible upon the upper surface of most specimens, with a lens of moderate power." "This species is comparable to the Sicilian H. globular is Ziegl., and the more flattened forms of If. platychela Mke. By the broad- er aperture, more strongly concave columellar lip, without trace of a tooth, it may be distinguished from these." (Martens.) The following variations are described : HELIX. 211 Var.

Covered umbilicate, conoid, spire exserted, striatulate, scarcely shining, solid, white or encircled by five castaneous bands ; whorls 5, somewhat convex, separated by linear, distinct sutures, regularly increasing, the last inflated, anteriorly abruptly deeply deflexed ; aperture very oblique, irregularly ovate, slightly lunate; peristome labiate with white, the margins considerably converging and joined by a distinct callus, upper margin expanded, outer and basal re- flexed, basal margin wide, distinctly expanded above the umbilicus, armed with a straightened callus or subdentiform fold within. Diam. 24, alt. 17 mill. Mts. of Beni Hosemar, Morocco. This species sustains the same relation to H. sicanoides that the Sicilian platychela bears to sicana. It differs from platychela (to which many examples are very similar in outline) in the constant presence of an umbilicus, the less reflected peristome and the pecu- liar apex. (Kobelt.) H. BOETTGERI Kobelt, 1881. PL 54, figs. 27-29. Covered rirnate, depressed conoid, solid, striatulate, microscopic- ally granulate, but not so distinctly spirally striate as If. tetuanenxis, whitish, or yellowish-green, variously painted with bands and flam- mules of brownish ; whorls 5, the first two forming a projecting apex, the following less convex, the last somewhat inflated, deeply deflexed anteriorly ; suture linear, impressed ; aperture very oblique, transverse-oval, the peristome acute, thin, strongly labiate with white, the margins converging, and joined by a thin callus, the upper expanded, outer slightly and basal distinctly reflexed over the rimate umbilicus, bearing inside a straight or dentiform callus. Diam. 20-21, alt. 13* mill. Mt#. Beni Hosemar, near Tetuan, Morocco. 212 HELIX. This form, which inhabits the more western mountains, is in gen- eral shape scarcely to be distinguished from many forms of the Sicil- ian H. globularis, but may be readily recognized by the sculpture and the columellar lip, which is not appressed. To the H. tetuan- ensis it holds about the same relation as globularis to platychela. (Kobelt.) H. GYROSTOMA Feruss^c, 1821. PL 54, figs. 20, 21. Covered perforate, globose, lightly obliquely striatulate, whitish- gray (bleached ?) with numerous small opaque white flecks, and larger, more translucent grayish markings ; this gray is above form- ed into flam mules somewhat, and below into two narrow bauds ; and upon these translucent tracts the white flecks are principally distributed ; whorls 4, the first relatively large, the second and third flatter, appearing decidedly carinated in the suture, the last inflated, well rounded, very strongly deflexed anteriorly ; aperture very ob- lique, comparatively small, circular, the terminations of the peristome joined by a thick shining white callus, its margins briefly expanded, white. (Martens.) Diam. 19s, alt. 12^ mill. Tripoli. In the early part of the century this Helix Avas found in Tripoli, and communicated by Dr. Leach to Ferussac; and again in 1879 a single example was taken by Dr. Erwin von Barry, in the first range of the Tarhuna Mountains. PI. 50, figs. 55, 50 are copied from the original figures of Ferussac. H. SCHERZERI Zelebor, 1868. PI. 60, figs. 86-88. Imperforate, globose-depressed, rather thin, striatulate, whitish, with sparsely scattered corneous points or also with five continuous brown bands; spire slightly elevated, apex obtuse; whorls 4?, slightly convex, the last inflated, anteriorly profoundly deflexed ; aperture very oblique, subcircular, peristome albolabiate, the mar- gins approximating, joined by a callus, briefly reflexed, the columel- lar obsoletely unidentate within, dilated and appressed above the axial region. (Pfei/er.) Diam. 20, alt. 11 mill. Gibraltar. This species is distinguished from the preceding and the following species, to which it stands nearest, by the entirely closed umbilicus. The columellar reflection is however perfectly sharply defined, and distinctly visible. From the H. marmorata, with which it lives, it may be separated always by the white lip. (Kobelt.) HELIX. H. TETUANENSIS Kobelt, 1881. PI. 54, figs. 30-3:1 Covered perforate, globose conoidal, beautifully undulately gran- ulate under the lens by the decussation of distinct incremental striae and very fine spiral impressed lines; rather thin, lustreless, unicolored dirty yellow or with brown bands, sometimes coalescent ; whorls 5, well rounded, separated by impressed sutures, the first forming a projecting apex, the last inflated and briefly, deeply de- flexed anteriorly ; aperture very oblique, lunate-rounded ; peristome acute, labiate with white, the margins converging, and joined by a callus, upper margin a little expanded, outer and basal margins reflexed, columellar lip expanded over the perforation, and bearing a strong dentiform fold inside.

Very slightly but always sensibly rimate, globose-subcouoid, apex exserted, rather thin but solid, unicolored whitish or yellowish, or with brown or blackish bands of various widths, striatulate ; w-horls 5, separated by distinct linear suture, the upper ones flattened, the following more convex ; body-whorl inflated, abruptly descending at aperture; aperture very oblique, rotund-lunar ; peristome labiate with white, slightly reflexed on the base, margins converging, joined by a light callus ; columella with a strong callus, sometimes denti- form below. Diam. 21, alt. 16? mill. (Kobelt.) Mts. Beni Hosemar, near Tetuan, Morocco. Very nearly allied to the Sicilian H. sicana, says Kobelt, but constantly separated from that species, after an examination of sev- eral hundred examples of each, by the umbilical rimation, of which sicana never has any indication, by the peculiar apex, and the less reflected peristome. H. SICANA Ferussac. PL 54, figs. 13-16. Imperforate, globular or bullet-shaped, thin but rather solid, whitish, unicolored or with three or four nairow brown or corneous subcontinuous bands, delicately opaquely striate, the surface decus- sated by numerous fine incised spiral lines, base nearly smooth; spire more or less elevated conic, obtuse ; suture linear, but well impressed and distinct; whorls 5-5 -j, those of the spire somewhat flattened, gradually increasing; body-whorl globose, rounded, very convex below, somewhat constricted behind the aperture, rather deeply deflexed anteriorly; aperture small, rotund-lunar, very ob- 214 HELIX. lique ; peristome white, narrowly reflexed, its margins converging, the columellar with a short callus plate inside, frequently truncate or subdentate at base. Diam. 21, alt. 18-21 mill. Near Palermo, Sicily. H. soluta (Ziegl.) Phil, is a synonym. Although quite variable, this species need be confounded with no other Sicilian shell. The imperforate base, strong spiral sculpture, small aperture and narrow peristome, as well as the globular form will distinguish it. B. The following group of Iberus contains shells with rounded periphery, generally rather smooth surface, and depressed form, the base usually indented at the center or perforate. They are charac- teristic of peninsular Italy and the Continent, rather than of Sicily. H. NICIENSIS Ferussac. PI. 64, figs. 14-18. Covered perforate, depressed, slightly shining, thin but rather solid, whitish, encircled by four or five spiral spries of brown or corneous spots, sometimes coalescent into irregular blotches above ; surface striatulate, and with sparse interrupted spiral lines above : spire low conic, obtuse ; whorls 5, the first forming a slightly salient apex, the following a little flattened, the last rapidly widening, de- pressed, rounded at periphery, slightly indented in the center of the base, rather deeply deflexed anteriorly ; aperture rounded-lunate. oblique, lilac colored within ; peristome labiate with the same color, slightly expanded, the margins subapproaching ; basal margin flat- tened, with a callus lamina within. Diam. 22, alt. 13 mill. Central France; Italy. H. nicceensis of Risso and of Rossmaessler is the same. H. SERPENTINA Ferussac. PL 60, figs. 59-65. Covered perforate, depressed, rather solid, opaque, somewhat shin- ing, lightly obliquely striatulate, whitish or yellow tinged, painted in innumerable patterns with deep chestnut, the markings generally more or less formed into narrow spiral interrupted zones, of which three (one subsutural, indistinct) are above, two (the outer more distinct) below the periphery ; or radiately maculate and strigate above, sometimes with the whole ground-color deep chestnut, upon which are zigzag white vermiculations and strigations ; spire de- pressed conoid, the apex subplanulate, corneous ; whorls 4 ?-5, the inner gradually, the outer rapidly widening ; body-whorl depressed, IIKLIX. 215 rounded at periphery, subflattened below, and indented in the cen- ter, anteriorly slightly deflexed ; aperture broadly semioval, oblique, whitish within, not showing the bands prominently ; pcristome nar- rowly expanded, slightly albolabinte, its upper and lower niar^in- subparallel, not converging ; columellar margin reflexed, appressed over the axis, dark colored, especially toward the umbilical callus ; parietal wall chestnut colored. Diam. 18, alt. 10 mill. Southern France ; Italy ; Corsica ; Sardinia. An excessively mutable form, which has been divided by authors into numerous species and varieties, the chief objection to which is the extreme difficulty of distinguishing them, even with the aid of good figures. The Marchesa Paulucci has made a critical study of the group (Bull. Soc. Mai. Ital., viii) and, except in considering hospitans, carce, etc., subspecies instead of species, I have not departed from her arrangement of the forms. Var. ISILENSIS (Villa) Mabille. PL 63, figs. 29-31. A pallid depressed form which is considered by the Marchesa Paulucci to be a variety or local race of the H. serpentina, the prin- cipal character of which is the total want of color. There are also individuals with dark dots or spots. Diam. 20-21, alt. 10-11 mill. Sardinia ; Corsica. Var. JASPIDEA Moq.-Tand. PL 61, figs. 20-22. Larger, bands not distinct above, marbled ; colors bright. Bonafacio, Corsica. Var. ISAR.E Paulucci. PL 61, figs. 23-25. Shell more rugose than the type, the interrupted zones paler ; no umbilical or parietal macula; columellar margin brown-punctate. Diam. 20, alt. 12 mill. Sardinia. Subspecies HOSPITANS Bonelli. PL 54, figs. 22, 23. A form differing in its rather larger more globose form from the typical serpentina. " The coloration varies from a whitish ground, all covered with dots of dark or pale brown disposed in series like interrupted zones, to a milk-white, without trace of markings. The spot which ornaments the base at the insertion of the columella, however, always remains constant, but even this is subject to great mutation as well in the intensity of its color as in the size. As for the form, the modifications are still more obvious ; for, whilst the 216 HELIX. type is rather globulose, the last whorl comparatively inflated, there occur with it forms almost angulate, and others actually carinated." (Mme. Paulucci.} Sardinia. The synonymy includes, according to Mine. Paulucci, H. inag- nettii Cantraine (non magnettii Mabille) and H. carte Kobelt (non carce Cantraine). The following form is described by the Marchesa Paulucci as a variety of IT hospitans, which is considered by her a species distinct from H. serpentina, although connected with the latter by transition forms. Var. ALABASTRINA Paulucci. PL 61, figs. 17-19. ' Differs from the type by the more globose, more solid shell ; the last whorl less dilated ; the brown umbilical and parietal maculation wanting ; columellar margin thick, alabastrine ; aperture small." Diam. 20, alt, 14 mill. Another form inhabiting Cape St. Ellas, has been called by Mme Paulucci mutation (or variety) porphydica. Its differential char- acters are found in the entire absence or great reduction of the spot at the insertion of the columella, and the coloration of the surface- which consists of small crowded maculations, which frequently have a tendency toward violaceous, instead of brown. Subspecies CAR.E Cantraine. PL 64, figs. 9, 10. Imperforate, orbiculate-convex, somewhat depressed, smooth, shin- ing, yellowish marbled and vermiculate with dirty white, ornament- ed with five brown interrupted zones ; spire prominent but subplane ; aperture ovate-lunate, white, as w.ide as high ; peristome reflexed ; umbilical callosity bordered yellowish.

Paulucci (Materiaux, etc., p. 34) says : "The type of this species, as it is represented in the work of Ferussac corresponds exact- ly with Mt. Maiella specimens which I have received from Dr. Tiberi under the name of H. marrudna (PI. 66, figs. 84-86). It is a shell with the umbilicus wholly closed, with pale bands, so interrupted as 220 HELIX. to be reduced to elongated points, widely separated from one another. A variety usually smaller, more depressed, and consequently with wider aperture, and having a faint brown spot at the insertion of the columella, has been described by Dr. Westerlund under the name of H. recondita. I have had the types of the species from Mr. Westerlund; they are identical with mine. It seems to me im- possible to separate H. recondita specifically." ; A second variety, more like the type in general form, and ap- proaching H. recondita in the columellar spot, has been named by me var. CONTAMINATA this variety frequently has the umbilicus partly open ; the coloration is like that of the type, but with the maculations or points more intense. It has below a more or less interrupted chestnut band." ' The third variety, which I have called UZIELLIANA (pi. 60, figs 76-80) is relatively very depressed, the columellar margin dark, the umbilicus decidedly open. It is the form which authors have look- ed upon as the type of the species, and called H. carseolana." Var. PERSIANII Tiberi. PI. 65, figs. 39-41.

Of this species, which was at first identified with the long-lost H. circumornata of Ferussac. Dr. Kobelt says : My examples show three bands of square reddish brown markings, which have their longer dimension in the direction of the incremental striae ; the middle ones are much wider than the two outer, and often formed by the co- alescence of the second and third. The arrangement of the markings is remarkably regular, as the figure of Ferussac indicates. The sculpture is like that of If. carseolana and also the form of the whorls, except that these are more raised, 'and no angulation is visible. The aperture more widely rounded, and relatively shorter than in the typical carseolana ; the terminations of the peristome are much less approaching, and the basal margin is less thickened by the callus. The peristome, too, is of a rather bright reddish-brown color, and only its very edge is white. (Icon. 1. u. suss. iv. Moll. Eur., etc., v.,p. 77.) Separated from H. surrentina by the greater elevation, and the inflated whorls, which are shouldered at the suture; from H. carse. olana by the closed umbilicus and the brown peristome. Its home is eastward from the Appennines, in that Apulian outlier of the Ap- pennines known as the Murgie. (Kobelt in Icon, etc., vii, p. 9.)

From surrentina the bluish-white color, less rounded, more sloping form, the body-whorl more swollen below, rougher sculpture, different color pattern, and especially the more circular aperture distinguish it. From fasco labiate, it is separated by the more sloping form, narrower last whorl, rounder, more oblique aperture and notably diverse sculpture. 224 HELIX. Var. OKTA Paulucci, PI. 65, figs. 69, 70.

POMATIA Beck, 1837. This section, like the preceding groups of Pentatcenia, is wholly Palsearctic in distribution, and is especially characteristic of south- western Europe and the adjacent portions of Asia. I have no hesi- tation in separating from the section the Australasian and American species which Pfeiff'er groups here ; as 1 believe that their resem- blance to the European types is merely superficial. The arrangement of species here adopted is substantially that of Kobelt's Catalogue. The large, globular form separates Poinatni from the allied subgen- era : it is subject to but slight modification in the various species, which are all, indeed, in general appearance very similar. The species of Poittutiti frequently exhibit sinistral monstrosities, and scalarit'oriu or partially uncoiled specimens are also not infre- quently found. Artificial monstrosities have been produced by in- serting the young Pomutiti into the aperture of an empty shell, such HELIX. as Linmcea stagnatis ; as the growth of the Helix proceeds, a normal globose variegated body-whorl is added to the artificial spire, and becomes solidly attached to it. That snails have more intelligence than is usually ascribed to them is shown by the following interesting paragraphs on the In- stinct of orientation in Helix aspersa by F. d'A. FURTA i><> : "In a house which I inhabited at St. Michael's one of the Azores, there was a veranda with a flight of steps leading to a little court or garden. Above this was a second veranda supported by a stone column, which rested on the wall of the lower veranda. At the foot of the column had been set a flower-pot with a young banana bearing two or three leaves. "One morning I noticed a snail (Helix axpersa) lodged between the pot and the column, as if waiting for night to attack the plant. A leaf had already been gnawed; and to stop further depredations I threw the snail into the court. It was not much Ihe worse for the fall, as it chanced to light upon a small manure-heap. Next morn- ing I was surprised to find the snail in precisely the same position as before, between the pot and column. I knew it by its size and color, as well as by a curious covering of spiders' webs which it bore. It was evident that the snail possessed a remarkable sense of direction, which enabled it after a violent shock, to make its way back over a distance of at least six metres in a very short time. In order to get at the bottom of the matter, I threw the snail back to the heap and watched the result, which was as follow : "June 10, 1884 At about !) A. M. the snail was resting, completely retracted within its shell, on the rail of the stair-case, having travelled nearly 4 metres. In the evening it resumed its march, but so slowly that by 10 o'clock it had only reached the top of the rail, where it stopped again, having traversed a metre in two hours. Twenty minutes after midnight it began to travel along the balus- trade of the veranda, taking at first a very undecided course, but as soon as it reached the edge of the balustrade making straight for the banana. Halfway it was turned aside by some fish-scales, which no doubt indicated that the surface was contaminated; but it soon regained its previous direction. Near the column it fell in with a grooved washing-board, which it seemed to remember; for it reared its head and tentacles towards it, while still two centimetres oil'. So far two metres had been traversed in twenty minutes. The snail now advanced resolutely from the board to the flower pot, as if over 234 HELIX. known ground (the board had lain in the same place for several days). I watched its movements by a lamp set far off so as to give only a faint light; but when it reached the pot the animal became shaded by weeds which grew there, and I found it necessary to bring the lamp near in order to observe the movements of the snail's lips and tentacles. It climbed the pot rapidly, mending its pace as it got nearer; then it examined the rim with care, and at last crawled over the mould. For a quarter of an hour it wandered among the weeds in the pot licking them frequently. When I saw it explore the soil with its lips and larger tentacles, while the re- productive orifice seemed to open from time to time, I thought that it was seeking a convenient spot to lay its eggs. At last it came up to the banana, mounted it, and began to gnaw the leaf previously attacked, exactly where it had left off before. I was standing a little way off to avoid disturbing the snail, but could readily detect the peculiar odor of the gnawed leaf. Very likely the snail could perceive, even in an uninjured leaf, that scent which only became apparent to me when the leaf was bruised or cut, and this may have helped to guide its course. Scent alone, will not, however, ex- plain all the movements of the animal. At. 2 p. M. I left it feeding. "June 11.- At 10 A. M. very little of the leaf had been devoured. The snail was comfortably established, as before, between the col- umn and the pot. "After this I noticed the snail wandering over a vine which trailed about the column and upper veranda. Finding that it was disposed to escape to the next garden, I opened it on June 17th, to see whether it was ready to lay eggs. There was not a single egg in the oviduct. "These observations seems to show that a land-snail may possess an instinct which enables it to choose its abode and return to it at pleasure. We have here the same love of home and topograph- ical knowledge which have been observed, and noted with wonder, in the limpet," #,# :]: Three subsections may be distinguished : POMATIA, s. sir., of which Helix pomatia may be taken as the type.

The narrower aperture, adnate columellar lip, completely closing the perforation, and of a dark brown color, will separate this form 16 242 IIKLIX. from H. pomatiu, with which it has some superficial likeness. The parietal wall has a very thin brown callus. Var. riMosTANS Blanc. Un.figured. Janiiiu. H.

The first formal diagnosis published was that of Albers, in I860 ; It is not certain, however, that he describ- ed the real obtusata (Ziegl.) Rossm., because hib diagnosis does not mention the large apex, which is the most prominent character of the species.
