Mr. E. A. Smith, in a paper on Loo Choo Shells (Proc, Zool. Soc. 317, 1887) remarks: H. despecta, Gray, (Manual, iii, 211), H. ravida, Benson, H. Redfieldi, H. Sieboldtiana, Pfr. and H. assimilis, A. Ad., are all very much alike and might well be considered varieties of one and the same species. In the series of eighteen specimens from Loo Choo I find considerable differences in form, some being much higher and more globose than others. One example is of a peculiar purplish brown color, and another is remarkable in having a thick- ening or limbus within the lip.

H. nemorivaga and H. arboretorum, Val. are synonyms. H. ana- choreta, Binuey (fig. 20) was founded on a less globose form of this species, without revolving band. In his latest monograph Mr, W. G. Biuney considers H. Nicldiniana a variety of H. Calif 'or niensis, Lea, a decision with which I by no means agree. I do not think H. Cal- iforniensis belongs to this group at all.

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.-

Section III, MACULARIA, Albers, 1850.

A group of large species, characteristic of Southern Europe and Northern Africa. They are related on one hand to Tachea, through such species as H. splendida, and on the other to the insular groups Hemicycla and Leptaxis. The Italian subgeuus Iberus is also con- nected by nearly intermediate forms with the depressed Macularire. The central teeth lack lateral cusps ; and the jaw, as in Tachea etc., is moderately arched, and bears a few strong, separated ribs.

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.

H. BURINI Bourguignat. PL 42, figs. 60-62.

The tubercles are strong, and situated so near to each other as to leave but a narrow space between them.

The synonyms are H. tigriana Bourg. and If. maresi Crosse. H. stereodonta Bourg. (PI. 43, figs. 68, 69) H. dicallistodon Bourg. (PI. 42, figs. 66, 67,) and H. surrodonta Bourg. (PI. 43, figs. 70, 71,) seem to be too closely allied to the H. tigri to warrant separation as dis- tinct species.

A white unicolored form is also figured (fig. 73.) The species is like all Macularice, variable in color pattern and size ; and in the Grecian peninsula occupies the place of H. alonensis in the Iberian.

Like that species, too, the codringtoni seems to be an esteemed delicacy of the cuisine ; for Roth relates that in the markets of Athens quantities of them are exposed for sale during the Lenten season.

Differs from H. campesina in being imperforate, with less devel- oped peristome, which is reflected and aduate to the base of the shell. The geuitalia offer some points of difference, according to Ross- rnsessler ; but until we have descriptions or figures of those of the allied forms we can scarcely make use of this character.

Section V, HEMICYCLA Swainson, 1840.

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- lariajobaeana 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. plicatula Lam., H. orbiculata Wood, H. planorbula Gray are synonymous. Some authors have included several allied forms under the name plicaria, but attention to the above diagnosis will enable any one to separate them. The sculpture of the ribs is very charac- teristic.

In form and appearance similar to H. plicaria, but distinguished by the thin shell, narrow (often subobsolete) bands, regularly spaced incremental costre, which are less developed than in plicaria, and without the secondary sculpture of incised lines shown by that spe- cies; the interspaces between costre are finely striate; the young shell is pilose.

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.

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.

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.

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.

"According to Mousson, H. p/anorbella presents two totally dis- tinct forms, — one of them peculiar to (iomera, with the cost a- simple or uugranulated, which he believes to correspond with the Lam- arckian type, and the other, which is more depressed and keeled, and has the ridges distinctly sculptured, to Teneriffe. This latter phasis, figured by Pfeiffer as the normal state of the If. planorbella, Mousson treats as a Var. incisogranulata (pi. 61, fig. 7-10), and de- fines it thus: 'umbilicus slightly narrower; plicae less numerous, minutely granulate by transverse incised lines; basal margin less adnate, less thickened, distinctly convex within.' ' (Wollaston^)

I have followed Moussoii's identification of this species, and as I have no specimens, have taken my description from his. Mabille, however, whose work on Heniici/r/n is more exhaustive than any other,, and who \x j><ir excellence, analytical m his methods, considers the "var. indsogranulata" the true planorbella.

His note on this point, (under H. quadrieincta, Nouv. Ardi. <lu Mas. d'Hist. Nat., 1885, p. 24,) is as follows: "Dans le planorbella, lesstries costulees sont iucisees exactenient comme celles du plicaria ; le caractere que signale M. Mousson n'est reel qu'autaut que 1'ou a en vue une variete de cette espece a cotes lisses, variete qui nous semble assez rare, et pourrait peut-etre, lorsqu'elle aura ete suflisam- ment etudiee, constitutuer une espece distincte" I am unable to de- cide upon the identity of a species upon which specialists on this fauna hold such diverse opinions.

This is not the paivana of Lowe (1861) which=fT. modesta Fer. On account of this preoccupation, Mabille proposes the name paivanopsis for this species.

"The H. paivana is a rather depressed but obtuse shell there be- ing no indications of a regular keel; its spire is only slightly raised, but somewhat blunt and dome-shaped ; and its umbilicus is partially visible, it being only half closed-over (or perhaps rather more) by the reflexed peristome. It is somewhat thin in substance, tumid beneath, and of a yellowish brown hue, paler below but ornamented with four narrow and regularly interrupted darker bands, which give a somewhat freckled appearance to the whole upper side ; and the surface is beset with coarse tubercles (which become obsolete toward the nucleus, and gradually disappear on the umbilical area), — caused by the breaking-up of the densely-packed oblique lines of growth."

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.

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

Diam. 18, alt. 13 mill. St. lago. Cape Verdes.

This species has not before been figured. I am not sure of the relation it bears to H. jogoensis, (see above), but from the other larger species of the Cape Verde group, advena and serta, the much greater development of the spiral sculpture and the more globose form will separate it.

I am inclined to refer to this species as a variety, a form figured on pi. 52, fig. 64. It is different in coloration, lacking the narrow articulated brown bands of the type. Probably this is the H. ar«n- joi (or arangoi) Dohru, a form never described or figured, and re- ferred by Pfeiffer to If. advena. My figure indicates that it is cari- nated; this is not the case.

" The H. subroseotincta in its small size and totally ungranulated surface has more in common with the H. bollei than it has with the leptostyla. 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."

Section VIII. IUERUS Montfort, 1810.

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.

HELIX.

This form is allied to H. rjlobularis, and especially to If.platychela, but may be separated by several characters from both of these Sicilian species. The peristome is nut so broadly expanded as in platychela, nor is it so decidedly dentate as is usual in that species; and there is not so obvious a flattening of the upper whorls as in the more depressed forms (which are nearest to melitensis) of platychelt.

Yar. CARUASLT: Pilsbry. PI. 62, fig. 54-56.

" 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.)

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.)

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.

This species is distinguished from the preceding and the following species, to which it stands nearest, by the entirely closed umbilicus.

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.

As for the form, the modifications are still more obvious ; for, whilst the

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.

This pretty variety is distinguished by its relatively almost smooth shell, as well as by the row of little spots scattered along the suture, a character which is completely absent in all the typical individuals. I have received this variety from Engineer Molteni, of Foligno (Umbria), mingled with a number of H. gtrigata. It appears quite common. (Paulucci.}

Mine. 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

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."

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.)

This is the H. circumornata of Kobelt, (1877), not of Ferussac.

The original figures of Ferussac are copied on my plate. The species has not been satisfactorily identified with any of the Italian Iberus.

Mabille, — a form which has not been, probably can- not be, identified with certainty. Under these circumstances, and in view of the extreme difficulty of distinguishing the species of Iberus, even when figured, If. ciofnloi had better be Jeft in obscurity until its claims to specific distinction are made more patent.

Section IX. 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

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,"

very pale, even when banded. The bands appear subtranslucent from within. The columellar lip is expanded only in the immediate vicinity of the umbilicus, and is closely appressed over it, differing in this respect wholly froni H. ligata, with which Bourguignat com- pares it. From H. cincta and its white variety pollinii, the differently formed, less expanded basal lip and columella will separate it. Kobelt has identified with this species a form of very different ap- pearance; so different that I am inclined to believe it specifically distinct. His description (translated) and copies of his figures (pi. •r>6, figs. 6, 13) are here given:

8hell imperforate, globose, whitish, encircled with two or three zones, rugose-striate, slightly shining; whorls 5, somewhat convex, rapidly increasing, the last large, dilated, gently descending at the aperture; aperture lunate-rotund, white within, slightly oblique; peristome simple, thick, albolabiate within, the columellar margin reflexed, appressed, dilated over the umbilical region, joined to the upper lip by a thin callus.

The synonymy is rather involved : It includes H. obtiitatu (Ziegl.) Rossm., 1838. (preoc), H.obtusa/is Mousson et auct., H. obtusata (Ziegl.) Albers, 1860 (?). 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. Rossmaessler simply figured, without descriptions, the obfitxiita of Zeigler and vulgaris of Parreyss.

An attractive species, which may he distinguished from the pre- ceding by the small apex. The pallid coloration, light, decu — ;itr<l shell, sometimes partly denuded of the very thin cuticle, are the more prominent characters.

The peristome is very narrowly expanded except at its insertion in all the specimens T have seen ; but a form figured by Kobelt ( pi. (>s. h'g. 21,) shows a considerable departure from the type in this respect. II. NOKDMAXNI Parreyss, 1859. PI. .~>7. figs. 16-18.

The following species are unknown to me; and are probably, for for the greater part, spurious.

Bourguignat, prefatory to his Description de quelques especes italo-pomatiennes de la serie des H. li(/</f<t /t lucorum, in Miseellanees Italo malacologiques. He says: "Jeconnais 162 especes d'Helix du groupe des Pnntatiu. 8ur les 162 espei-es, j'en possede 151.

H. HUMBOLUTIANA Valenciennes, 1841. PL 69, figs. 34-3*'..

Narrowly umbilicate, depressed-globose, rather thin but solid, opaque, with a very thin yellowish-brown cuticle, encircled by three dark chestnut bands, which are narrower than their interspaces, two above, one below the periphery, more or less interrupted by longitu- dinal irregular whitish streaks ; rudely, irregularly striate, com- pletely covered by a dense h'ne granulation ; spire low conoid, ex- centric, with blunt apex and smooth polished first whorl ; sutures well impressed ; whorls 4<V, well rounded, rapidly increasing, espe- cially the last, which at the aperture is double the width of the penultimate; body-whorl large, depressed-inflated, deeply indented around the umbilicus, descending anteriorly; aperture rotund or oval, lunate, quite oblique, pinkish-white and showing the bauds within ; peristome obtuse, slightly labiate, regularly arcuate, its ter- minations converging, outer and basal margins subexpanded, colu- mellar margin at its insertion triangularly expanded, adnate above the umbilicus, which it narrows and conceals more or less, joined to the superior margin by a light white callus.

Central Mexico.

H. badiocincta Wiegm., rnss., teste Pfeiffer, is synonymous.

A beautiful species formerly classed in Pomatia, but doubtless be- longing in Odontura. It is quite variable in proportions, a large specimen before me measuring: diam. maj. 40, min. 28, alt. 34 mill.

In this large form the shell is transversely expanded, the whorls obliquely flattened above, giving the spire a conoid shape, and the aperture is transversely oval. The thin cuticle exfoliates very readily.

Var. BUPFONIANA Pfeiffer, 1845. PI. 69, fig. 37.

More coarsely obliquely striate, thinner, less distinctly granulate, darker in color, the bands indistinct, reduced to two. last whorl more inflated, peristome less expanded. Diam. 37, alt. 35 mill.

In the text I considered H. chilembia Bonrg. a form of var. hem- prichti, on account of a series which seem to connect the extreme forms. It may be better to admit the form as a distinct variety.
