The description of Orthurethrous snails is continued in this- volume, the remaining groups of Ferussacidce and the Partu- lidcs being described. In treating of the latter family, the author has had the advantage of studying the types and other specimens of the late Dr. W. D. Hartman, now forming part of the collection of the Carnegie Museum at Pittsburgh. The conclusions reached in the monograph now published have thus been based upon the material of two large collections. The liberality and courtesy of the Trustees of the Museum and of the Director, Dr. William J. Holland, are here grate- fully acknowledged. H. A. P. (iii) 196906 DATES OP ISSUE OP THE PARTS OF VOL.

About ten years ago the writer pointed out the existence of three great groups in the monotremate land snails, based upon the structure of the pallial organs: SIGMURETHRA, HETERURETHRA and ORTHURETHRA. The first group includes a very large majority of the land snails now existing, which have been described in volumes I to XVIII of this work. The Heterurethra are chiefly represented by the genus Sue- cinea. Finally the group Orthurethra is made up of a series of families which retain primitive pallial structures like the Basommatophora. They are the scattered descendants of snails of long ago — of the first land-snail fauna. With the rise of the Sigmurethra, these primitive snails declined. On the continents they take a minor role, and seem to exist by grace of their insignificance (Pupillidcz, Valloniida, Ferus- sacida), though one family, the Enidce, contains snails of moderate size. On the Pacific islands, where the Sigmurethra are represented by only a few low forms, Orthurethra are still dominant. In this island world the Partulidce, Amastrida, Ackatmellida and Tornatellinidce comprise the most con- spicuous elements of the snail-fauna. The following families are now comprised in the group Orthurethra : Valloniidae (See Vol. VIII, p. 247, and IX, p. 282). Holarctic. Enidae (Buliminidce of authors). Pala&arctic, Oriental, African. Pupillidse (Pupida of authors). World- wide. Partulidae (this volume, p. 155). Polynesia, Melanesia, Micronesia. (vii) Vlll INTRODUCTION. Ferussacidae (Vol. XVIII, p. 211; this volume, p. 1).

Marginal teeth low, wide, with two low, denticulate cusps. The genitalia, as figured by Lehmann for C. acicula (pi. 15, fig. 1) have the duct of the spermatheca very short. An appendix, enlarged at the end, is terminal on the penis. There is also a short accessory organ anteriorly on the penis. Type C. acicula Mull. Distribution, Europe and most tropi- cal and subtropical countries. An excellent account of Cascilioides acicula has been given by Mr. L. E. Adams, as follows: " Methods of Progression. — Usually the shell is dragged along the ground after the animal, though more rarely it is lifted to a horizontal position (pi. 1, fig. 6). On two occasions I observed the animal protrude its head under the shell towards the spire and progress in that direction, forc- ing the shell along the ground in front of it, apex first, and then lift the shell over its head at an angle of about 45 degrees, and continue its march in that position (fig. 5). The progression is always by slow jerks, and not a continuous glide. I have not observed the shell carried in the position of Jeffrey's figure (British Conchology, Vol. I, pi. 7, fig. 18), though Nilsson says * the animal sometimes carries its shell erect, but generally drags it along depressed.' " Texture and Form of the Animal. — I was much struck with the extremely flexible and elastic nature of the animal. I have observed one emerge from the shell as it lay flat, on a hori- zontal surface, and make a complete circle with its head and tail, without moving the shell. It is also remarkable how far the animal will protrude from the shell, and how slender an attachment connects the head and foot with the part within the shell. The end of the tail is often curled up. Along the neck ;ind down the front of the head are two mucus sulcations on either side of the dorsal line (pi. 1, fig. 8). The tail is pointed and sharply carinated; from the dorsal ridge mucus sulcations descend to the lower edge (fig. 7). " Eyes and Tentacles. — Jeffreys' enlarged figure (Brit. Conch., Vol. I, pi. 7, fig. 19) is not quite accurate. He seems to have taken his description from Nilsson, and it may be doubted whether Jeffreys himself examined the animal with sufficient care. Nilsson had evidently studied the animal, but he was not correct in describing the upper tentacles as ' not thickened. ' In all the specimens that I have observed the upper tentacles are certainly slightly bulbous when fully or nearly fully ex- tended, though this does not appear when they are only slightly protruded. Nilsson, however, correctly remarks that the apices of the upper tentacles are not ( marked with a black spot.' Now Lamarck (to whom Nilsson refers) seems to have been the only one to observe the colorless eyeball, and he did not recog- nize them as such. Nilsson says (quoting Lamarck) "In this species no eyes indeed are exposed, unless they are white, like the tentacles themselves. These, indeed, are terminated by a convex surface, very smooth, very shiny, surrounded by a slightly impressed ring; which surface doubtless answers to the eye of other terrestrial mollusks. But this animal, probably because it lives underground, where it cannot use eyes, appears to us plainly to lack eyes.' Now I have noticed that these peculiar convex endings with a constricting ring are in fact eye- balls, and also that they are retractile, but whether they have retained the power of sight in spite of their loss of pigment, I am not prepared to say (see fig. 8). As far as my observation goes, the animal is insensible to light, though it will crawl straight away to a heap of moss; the direction, however, may be determined by scent alone. If it is deficient in sight it cer- tainly uses its tentacles to all appearance in the same manner as its more favored brethren. I may mention in this connection that an albino specimen of Limax maximus, whose eyeballs were also destitute of pigment, seems to act in a perfectly normal manner. Though my observations on this point (Journal of Conch., Vol. 9, p. 24) tend to show that this species is lacking in sight, I am not aware to what degree of perfection the vision of terrestrial mollusks attains, but I have noticed that Oydostoma elegans and Helix pomatia seem sensitive to the approach of a large' object." (Lionel E. Adams in The Journal of Conchol- ogy, Vol. 9, p. 297. ) 4 (LECILIOIDES. Cdecilwidea is well known to inhabit graves. Gaudry found them in lacrymatories unearthed from Grecian tumuli. Rev. H. Housman records that near Chichester in "an early British burying-ground many skeletons were found. The bones, which lay about three feet below the surface were infested with A. adada" (Journ. of Conch, iii, 1882, p. 317). In North- amptonshire Messrs. Wright and Adams found Ctedlioides abundant to a depth of 4-J ft. , in a place where skeletons of men and horses have occasionally been discovered (J. of C. viii, 1897, p. 395). J. W. Horsley reports them similarly from a Saxon cemetery near Witney (J. of C. ix, 164); and in Germany Professor von Martens has recorded the presence of a great num- ber of large fresh specimens in a human skull dug up at Bern- burg (Nachrbl. d. Mai. Ges. 1883, p. 60). Definite information upon the food of Csecilioides is wanting, but they probably feed upon vegetable matter, such as subter- ranean fungi or possibly fine rootlets. The European species of Csecilioides have no doubt been multi- plied beyond reason, yet without a critical study of the types it is impossible to say how many recognizable races exist. M. Bourguignat and his friends had an agreeable custom of describ- ing "species" from single selected specimens, ignoring connect- ing forms. Published figures of shells they had never seen occasionally served as a basis for supposed new species; so that in the identification of real shells there is some excuse for pass- ing over much work of these authors with a light heart and careless eye. I have neither the time nor type-material to at- tempt a critical revision of these forms. It is a work which properly belongs to some European student who will make a study of the local races, of the significance of variations, whether individual or racial, and finally he must study Bourguignat's types. This work demands great application and large series of the shells, unprejudiced by selection or determination. I have been able to do little more than give an account as full as the original sources admit. The American forms are treated more fully, my material being ample, and the literature less overloaded. The generic name has been variously spelled, but the earliest C^ECTLIOIDES. 5 valid form is undoubtedly Csecilioides, in reference to the blind- ness of these tiny subterranean snails. Aciculina of Wester- lund is an absolute synonym of Cxcilioides, having for type the same species, 0. acicula. Gsecilioides occurs in typical species in the Miocene and Plio- cene, the following species being known. All were described under the name Cxcilianella. Cdecilianella grateloupi Bgt.

According to Wollaston, this species differs from C. acicula by being smaller, narrower, thinner, paler, more highly polished and more transparent; its spire, which has a volution less, is shorter and a little more obtuse at the apex, its suture is less oblique, its columella is relatively somewhat longer and etraighter, and more flexuous, and its entire outline is both narrower and more fusiform.

"The most important feature which separates the A. eulima from the acicula consists in the presence of a conspicuous medial plait on its ventral paries ; but it has other characteristics also which combine to separate it from that species. Thus it is not only longer, more cylindric, and proportionately still slenderer, with a tendency to be obsoletely bent (as in the marine genus Eulima^ but its whorls (particularly the intermediate ones) are altogether more lengthened-out and flattened, and its aper- ture is relatively a little shorter, as well as broader (and more rounded) posteriorly, the basal margin being more obtusely arcuate, and merging almost without an intervening angle into the columella, which is narrower gradually (and is not abruptly truncate) behind. The suture is exceedingly oblique, and its surface is of a hyaline white." (Wottaston). This species apparently belongs to the section Rhaphidiella of Maltzan. See species No. 6. 3. C.

This species is distinguished from G. acicula by the irregular increase of its whorls, the antepenultimate or penultimate sud- denly widening more rapidly than those before, and by the narrow, subvertical truncation of the columella, that of acicula being wider and more approaching horizontal. The species of Bourguignat was based solely upon Albers' account; and the latter, in my opinion, applies to this form rather than to the real C. acicula. Bourguignat had not actually seen the Madeiran shell. The Sicilian C. actoniana, rizzeana and petitiana are apparently identical specifically with nyctelia, — or at all events, there seems to be no difference in the shells. How many other of the 11 species" are really the same I do not know.

A large proportion of the specimens in collections are from drift debris of rivers, hence forms from various colonies and diverse stations are mingled in unwonted company. Such lots are misleading in the study of variation. Var. elongata Locard. Of a slimmer, more lengthened form. Var. ventricosa Locard.

Unfortunately I have not access to de Betta's " Esame Critico" in which he figures the CJECILIOIDES OF ITALY. 23 species. Westerlund's account, which I have used above, seems to have been taken mainly from Kuester s article of 1870, which was the first critical discussion of the species. Var. gredleri Kuester.

Aperture narrow, lanceolate ; peristome unexpanded acute, arching forward. Columella short, slightly arcuate, obliquely truncate, margins joined by a callus. Length 5.5, diam. scarcely 2 mm. (Acicula gredleri Kuester, Neunter Ber. Nat. Ges. Bamberg, 1870, p. 94). "One might say that this species represents a shortened, widened aciculoides, just as veneta seems to be a derivative of acicula. The slender shell is fusiform, but the greatest width is below the middle." The types were found at Trient with A. veneta by Professor Gredler. One example was found by Dr. Kuester at Triest. 14. C.

The moderately increasing whorls are somewhat convex, the upper margin noticeably thickened, narrowly bor- dered. The base of the last whorl is very lightly arcuately tapering. The bend of the columella is indistinct, the trunca- tion at its base oblique. The ends of the peristome are joined by a distinct deposit. Length 5, diam. 1.33 to 1.5 mm. (Kuester, 1870). This species was quite unrecognizably described by Jan, but it was redescribed in 1852 by Edoardo de Betta, from specimens received from Jan. I have translated de Betta' s description and reproduced his very poor figure. Kuester ably discussed the form in 1870, having specimens received from de Betta, and others collected by himself at Triest. 15. C. PEDEMONTANA Pollonera.

Several lots, all from Benoit, are before me. The extremely thin hyaline shell has a conspicuously margined suture. The upper part of the spire is slightly contracted. The first whorl increases in width very rapidly, the next \\ increase but little; then the width increases rapidly again, the suture descending more obliquely. Its descent is most oblique in the middle of the last whorl, somewhat less so towards its end. The outer lip arches very strongly forward, the greatest convexity being below the middle. The parietal wall has only a thin callous film. The colurnella is concave, has a callous edge, and is obliquely but quite distinctly truncate at the base. Length 4.3, diam. 1.3 mm.; whorls 5. 17. C.

This species is comparable to C. jani de B., having the sharply truncate columella of that, but it does not reach nearly the size — 5.5 to 6.75 mm. long, 2.25 to 2.5 wide. C. jani has also a much more ventricose last whorl and distinctly more acute apex. (Bttg.) 26. C. TORTA (Mousson). Aperture at the base a little compressed; columella incurved, terminating in a twisted thread. This species resembles that of Lombardy in general appearance, so that for the time being it may be regarded as a variety of it, characterized by having the aperture slightly contracted towards the base, and the columella abruptly truncate. The single example, taken at Sayda, is not sufficient to establish well these differences. (Mousson). Syria: Sayda (Prof. Bellardi). Glandina (?) aciculoides Jan., var. torta Mouss.

According to Mousson, there are fewer whorls than in C. adcula; the apex is larger and more obtuse, the last whorl is more cylindric, and the remarkably narrow aperture has the free margin descending in a straight line curving towards the end of the columella and without surpassing it. The columella is but slightly concave and is obliquely truncate at the base. The figures are copied from Boettger, and represent specimens from the drift of the Sarus river, where this species is common. He remarks that the examples vary quite noticeably in size but normally it is 4 to 4.5 mm. long, 1.12 to 1.25 mm. wide.

Paladilhe probably had two species mixed in his lot of C. isseli. The description is that of a Ctztilioides, possibly identical with Nevill's second species (Handlist Ind. Mus. p. 162), and with A. balanus of Hanley and Theobald (Conchologin, 38 CJKCILIOIDE8 OF TROPICAL AMERICA. Indica, p. 41, pi. 102, f. 10, copied in my fig. 61 of plate 4); while the figure given by Paladilhe, which I have copied, seems to belong to C. (Geostilbia) balanus. Further investigation of the C&cilioides of Aden and India is much needed. Whether the observed differences in the columella indicate several species, or are extreme aspects of variation in a single stock, are ques- tions I can throw no light upon. Species of tropical Asia, West Indies, etc. Tropical countries have a few species of (J&cilioides of two groups: (1) the group of C. iota, comprising very minute species 1.6 to 2.5 mm. long, markedly cylindric, with the whorls nearly flat. All are American. (2) the group of C. gundlachi, with the shell larger, usually 3 to 5 mm., composed of convex, very obliquely coiled whorls. The columella is only quite obsoletely truncate. These groups are known as Caecilianopsis and Oeostilbm. Section C^CILIANOPSIS Pilsbry. Cacilianopsis PILS., Nautilus xxi, July, 1907, p. 28, for (7. jod = C. consobrina veracruzensis.

The type lot at Amherst consists of three specimens. It is a CvECILIOIDES OF TROPICAL AMERICA. 39 gubcylindric shell, obtuse at both ends, of scarcely four whorls in most examples, 4J in the longest. The shell is clear corneous when fresh, showing the internal walls through, but it weathers to milky white. The whorls are only slightly convex, and are separated by a moderately impressed suture, margined below. The suture is at first nearly horizontal, but at the last 1£ or 2 whorls it descends rapidly, the width of the whorl progres- sively increasing. The aperture is acuminate above. Outer lip arches very strongly forward. The columella is more or less concave below, and is rather abruptly truncate above the base. Columellar callus usually moderate, but variable in thickness. Under a high power, an extremely minute spiral striation may be seen near the base. Measurements are as follows: Cotype, Adams coll.: length 1.75, diam. .5 mm. Bellevue; fig. 72: length 2, length aperture 0.8 mm. Fig. 71: length 2, diam. 0.6, aperture 0.75 mm. Fig. 67: length 1.65, diam. 0.5, aperture 0.75 mm. C. iota has been found only in Jamaica. It is readily dis- tinguished from other tropical- American species by its much narrower contour. Exact measurements which I have made of a large number of specimens from several localities show the difference in shape to be constant. Pfeiffer's figure of this species in the Oonchylien Cabinet is very poor. It shows no columellar truncation, and hence 0. iota was classed by Crosse and others in Geostilbia. Adams's type specimens, as well as numerous examples before me, have a distinctly truncate columella. 38. C. CONSOBRINA (Orbigny). PI. 5, figs. 81, 82.

This species is closely related to C. iota, from which it differs by the stouter, more robust figure, specimens of the same length being invariably wider than iota. The general shape is slightly tapering cylindric, very obtuse at the ends. The whorls in- crease a little more regularly than in iota, the last turn of the suture being less oblique, though descending faster than the preceding one. This acceleration of the rate of descent changes the appearance of the shell and the proportionate size of aperture to total length with age, so that the addition of a whorl or even less alters the contour remarkably. The surface is lightly marked with growth-wrinkles and minute engraved spiral lines, visible only under a compound microscope. The columellar truncation is distinct, but rather weak in some examples. Two specimens from a lot taken by Gundlach are figured. PI. 5, fig. 82: length 2.4, diam. 0.8 mm. PI. 5, fig. 81: length 1.9, diam. 0.7 mm. The former of these examples corresponds to the type of A. pygmaa Pfr. ; the latter, a younger shell, agrees with Orbigny's type of A. consobrina. In my opinion these two names apply to one and the same species, in slightly different stages of growth. Pfeiffer's description of A. pygmaa follows. " A. pygmaaPh. Shell cylindric, smooth, pellucid hyaline, the apex rather obtuse. Whorls 5, rather flattened, separated by an oblique, lightly impressed suture, the last f the total length. Columella nearly straight, forming an angle with the belly of the preceding whorl, subtruncate at the base of the oval-elliptical aperture; peristome acute, the right margin dilated forward.

In this form the microscopic spiral striation is more dis- tinctly developed than in consobrina, visible from the suture to the base, the striae appearing crimped or waved (fig. 79).

H., xviii, 1856, p. 435.— WOLLASTON, Testacea Atlantica, p. 545. Pfeiffer's description of this shell is not very good. It tapers regularly to the very obtuse, rounded apex. There are 5 whorls, very obliquely coiled, quite convex, and parted by impressed sutures. The last whorl is evenly convex. The aperture is ovate, effuse at the base; the outer lip arches forward strongly in the middle. The columella is a little concave, and near the base is obsoletely truncate. It has a rather heavy callus in most fully adult shells, which passes up over part of the parietal wall. The color is pale corneous-brown, or sometimes almost clear corneous. There is no spiral striation. Two Cuban exam- ples figured measure: Length 4.2, diam. 1.25 mm. Length 3.85, diam. 1.1, apert 1.3 mm. The figures do not well show the heavy callus upon the colunella and lower part of the parietal wall. This is a somewhat common and widely distributed species, probably to be found throughout the Antilles. It was taken many years ago in Princeton, N. J., no doubt imported with West Indian plants. These specimens were reported as C. aricula in Binney' s "Manual." It occurred also in St. Helena, though whether it still survives there is unknown. The New Caledonian Geostilbia caledonica is in all probability the same species, a colony having been derived from Guadaloupe or some other Antillean source. At all events I am quite C^ECILIOIDES, SECT. GEOSTILBIA. 45 unable to see any difference in the shell. The original descrip- tion follows. G. caledonica: PI. 4, figs. 58, 59, 62.. " Shell imperf orate, fusiform-cylindric, thin, polished, diaphanous, clear-corneous. Apex abruptly rounded, very obtuse; suture hair-marginate; whorls 4, slightly convex, the last slowly descending, slightly more than half the total length. Aperture long-pirif orm ; peris- tome simple, unexpanded, thin, not acute, slightly thickened, the margins joined by a very thin callus; columellar margin having a longitudinal, small, diaphanous, glossy internal lamina giving the appearance of a basal truncation, not reaching the base.

Macrospira aperta Guilding has never been described. Too poor and dissimilar outline figures were given with this name by Swainson, without locality, dimensions, or any other par- ticulars. In 1892 Mr. E. A. Smith stated that A. gundlachi and veru were equivalent to aperta] and in 1895 he identified Geostilbia caledonica Crosse as a synonym of Megaspira (sic) aperta, from the comparison of specimens in the British Museum. In my opinion, M, aperta was not sufficiently defined by Swainson to be recognized. Its identity with C. gundlachi rests upon Mr. Smith's identification of specimens from Guilding, the locality of which is surmised to be the West Indies, but ie not positively known. No description of even these specimens has appeared, and Swainson' s figures are extremely crude. 41. C. BALDWINI Ancey.

Specimens of presumably this species are in the Bishop Museum at Honolulu from the following places: Rocky Hill, Honolulu; Kanaohe, Oahu; Mana, Hawaii. I have no exam- ples at hand, but so far as the description goes there seems to be no difference between this species and C. gundlachi. 42. C. BALANUS ('Benson' Reeve). PI. 4, figs. 60, (61?)

I have not seen this species, which seems to be rather common in the higher, dry parts of India, and to be known chiefly by river-drift specimens. Pfeiffer's description and the figures of Reeve and Pfeiffer indicate a shell with only weakly-truncate columella, so that one understands why Colonel Beddome should compare Geostilbia caledonica, (which he states is identical with Indian specimens from North Canara, see Blanford, I. c.). Nevill also refers the species to Geostilbia. In his description of C. isseli, Paladilhe mentions emphatically its truncate columella; yet his figure seems to represent a Geostilbia very close to balanus. Blanford has stated that isseli is identical with balanus', but so far as I can judge from the literature, there are two species involved. Fig. 60 is copied from Reeve's type figure. I have also copied the figure given in Oonchologia Indica, pi. 4, fig. 61. By its strongly truncate columella, this figure seems to cor- respond with the description of C. isseli. 43. C.

Not Electra Lamouroux, 1816, not Electra Steph., 1829. The shell is imperforate ovate-conic or turrite, brown or corneous-brown, glossy and usually without strong sculpture; apex obtuse. Aperture irregularly oval; outer lip unexpanded, acute or blunt; columella short, more or less deeply concave, abruptly truncate at the base. Sole without distinct median area; no pedal margin; an outer mantle lobe on the left side. Kidney very long, band-like. GLESSULA. 51 Genitalia peculiar (pi. 15, figs. 2); there is a feather-like gland (fig. 3) where the vas deferens enters the penis. The latter contains a short conic, perforated papilla and two of longitudinal folds. The prostate gland of the hermaphrodite duct consists of entirely separated narrow follicles, as in Achatina. The spermatheca has a short duct. Uterus contain- ing several large shells with fully 2 whorls. The jaw is very finely striate, almost smooth. Radula has ahout 110 teeth in a transverse row. The central tooth is very small, tricuspid; laterals with three cusps; outer marginal teeth very finely 3- or 4-cusped ( G. orophila from Madras, according to Semper). Type G. gemma Bens. Distribution, Oriental and Ethiopian regions. Glessula was associated with " Oionetta" (that is, the Ferus- sacida as herein understood) by Professor von Martens in 1860. Various other authors, both before and since, have thought the group Achatinoid, belonging to ' * Stenogyra " in the former wide limits of that term. We know too little of its anatomy to give a definite opinion, but the presence of a glandular append- age (appendix or flagellum) at the end of the penis is a feature unlike any Achatinida. The homology of this appendage is not certain, however. The position of the ureter is unknown. I have been unable to obtain alcoholic material necessary for an investigation of the relations of Glessula to Subulina, Homorus, Bacillum and Pseudoglessula. In most (but perhaps not all) species, the lip becomes slightly blunt and smooth in fully adult shells, thereby differing from Subulina, which has an acute lip at all stages or growth. In G. orophila, Semper found in the uterus 4 large embryos with shells having fully two whorls, and a small one with a half whorl and very large caudal vesicle. Various other species have been found to be viviparous, while others bring forth globular eggs like those of Subulina. Like that genus, also, the Glessulse reproduce before attaining full size. Glessula has been studied mainly by specialists on the Indian fauna. Benson, W. T. Blanford, Beddome and Godwin- Austen have chietiv contributed to thf literature. Blanford's 52 GLESSULA. "Contributions to Indian Malacology," continued through many years of the Journal of the Asiatic Society of Bengal, contain a great mass of information on this genus, as on many others of the Indian fauna. Hanley and Theobald illustrated most of the types of Benson, among others, in their Conchologia Indim. Finally, Colonel R. H. Beddome has recently reviewed the genus in his "Notes on Indian and Ceylonese Species of Glessula." From the purely conchological standpoint we may be said to have an extensive knowledge of Glessula, yet various characters of the first importance have been neglected. The embryonic whorls of the types must all be re-examined and their sculpture de- scribed. Our ignorance of the embryonic sculpture of many forms prevents any natural classification of the species. The surface of the later whorls in all the species should be examined under high power, since some species have a minute sculpture not visible with an ordinary hand lens. No fossil species of Glessula are known to me. A few species of other genera have been referred to Glessula. Glessula obtusa and G. erosa Blanford are species of Bacillum (Vol. xvii, pp. 1, 4). Glessula orthoceras G.-A. is a Bacillum (I. c., p. 2). Glessula philippinensis Semper, of Cooke, is a Cezcilioides (this vol., p. 49). No natural classification of the species of Glessula can be attempted until the sculpture of the apices of the shells and the anatomy of a number of representative species are studied. I have separated a group of West African forms (species 89 to 92) as a new section, Neoglessula. The species are here grouped geographically, as follows: I. Ceylon, species 1 to 13, 34, 49, 52. II. Peninsular India, species 14 to 58. III. Extra-Peninsular India, Indo-China, Yunnan, etc., species 59 to 77. IV. Habitat unknown, species 78 to 80. V. Sumatra, Java and Borneo, species 81, 82. VI. Eastern Africa, species 83 to 86. VII. West Africa, species 87 to 92. GLESSULA, CEYLON. 53 I. SPECIES OF CEYLON. The Ceylonese Glessulse are closely related to those of southern India, and in a few cases seem to be of identical species. Such cases should receive very careful comparison.

On the spire these striae are separated into groups by occasional deeper grooves or larger stria?; and more or less trace of such irregularity may often be traced on the last whorl. Under the compound microscope, the surface is seen to be very densely covered with minute granules arranged in spiral lines (pi. 6, fig. 16). These give it a charac- teristic silky sheen, unlike the smooth species. Specimens before me measure as follows, all being adults with the lip blunt. 54 GLESSULA, CEYLON.

Smaller than G. nitens, and of a richer brown color, but otherwise it is closely related. The whorls are strongly con- vex and the surface very brilliant.

"This little species of a group which has so many rep- resentatives in Ceylon, the Nilgherries, and the damp woody mountains of the North-eastern India, with a more slender form than A. oreas nobis, is well distinguished from the allied forms by its peculiar sculpture under the lens, and by the internal incrassation of the peristome, a feature which is also observable in the species A. crassilabris nobis. from north-eastern India." (Benson.) This species has not been figured. With the same dimen- sions as G. deshayesi, it seems to differ by having the whorls only very little convex, whilst in deshayesi they are strongly convex. 8fl. Var. taprobanica Pils., subsp. n.

It is doubtfully distinct from G. ceylanica, but from the figures, that seems to be more straightly conic and smaller. 10. G. LAYARDI Pilsbry, n. sp. PI. 7, figs. 6, 7. The shell is oblong-turrite, yellow-corneous with profusely scattered whitish dots and spots (produced by disintegration of the surface), paler towards the summit. Surface very glossy, without noticeable microscopic sculpture, but marked with unevenly spaced grooves, which are rather weaker on 60 GLESSULA, CEYLON. the last whorl, and obsolete on the base. The summit is ob- tuse, rounded, first whorls smooth. Whorls 6%, moderately convex. Suture elegantly but somewhat irregularly denti- culate. Aperture vertical; outer lip obtuse; columella very short, moderately or deeply concave, subhorizontally and very deeply truncate. Length 14, diam. 6, length of aper- ture 5.9 mm. Length 13.5, diam. 6.1, length of aperture 5.9 mm. Ceylon (Layard). This species differs from G. ceylanica by its very much less deeply concave columella. It is a smaller and more slender shell than G. serena, which seems to be its nearest ally. The denticulation of the suture is a prominent feature. Though "live" shells, the surface is eroded in places. The whitish flecks probably will not be found on shells from stations where they are less liable to erosion. 11. G. VERUINA (Benson). Shell cylindric-turrite, very much lengthened, dirty whit- ish, unevenly striate; the spire gradually tapering above; suture impressed, crenulate ; apex obtuse.

This minute form has about the size of a Tornatellina, but seems to be more strongly sculptured than is usual in that genus. The embryonic whorls are smooth, a little darker than the rest -of the shell. Four specimens were taken, two of them smaller than the type, which is thought by Jousseaume to be immature. II.

''Full grown specimens were very rarely found by me, though young half- and three-quarter grown ones are most abundant on the Nilgiris. This and some other species cer- tainly breed before the shell attains full size or a hardened peristome, as I have taken eggs from such shells. The peris- tome differs much in mature specimens, sometimes being very thick and solid, sometimes quite thin, but, even then, firm, and not breaking or becoming jagged at the touch, which is the sign that the shell has not finished its growth. Full-grown examples of shiplayi are very like tenuispira, but smaller. It also runs nilgirica very closely, but the latter has a stronger sculpture, and is broader at the base." (Bedd.) 15. G.

Blanf.) from near Trichinopoly, which is distin- guished by greater diameter in proportion to the length, and a more regularly tapering spire. Intermediate forms may hereafter be found however. "A specimen from the Shevroy hills near Salem in south- ern India, sent to me by Major Beddome, only differs from O. hebes in being longer and slightly more attenuate towards the apex. It has 13 whorls." (Blanf.) "Ten specimens received from Blanf ord and E vizard, col- lected near Poona, are all young, with quite unformed lip; and all the types of hebes in Blanf ord 's collection, and the specimens in the Natural History Museum and others that I have seen, are the same. If full-grown, or nearly so, it must be a much smaller species than shiplayi. It runs the young of that species rather closely, but the apex is gener- ally blunter. Specimens collected by me on the Shevaroys are referred here by Blanford ; they are, however, immature and appear rather to belong to fairbanki, if that species is distinct, which I doubt. When collected I took them to be young of shiplayi. Until hebes and fairbanki are found with mature lips, they must, I think, remain doubtful species. "Hanley's figure of hebes has the tapering apex of young shiplayi and is unlike my type of hebes." (Beddome.) 16. G. FAIRBANKI (Benson). PL 9, fig. 7.

No locality for it is mentioned. He writes : ' ' This shell has relations to A. chessoni in the attenu- ation of the spire towards the summit, a feature observable also in the northeastern A. tenuispira. It differs in form, size, proportions, etc. In one specimen from Bombay the attenuation of the spire is less conspicuous." Col. Beddome states that the specimens he has seen are in no way separable from tenuispira. The initial half whorl is smooth; then very fine, close, regular vertical striae appear, continuing to the end of the embryonic shell, which consists of two whorls (fig. 9). After this, the strise are irregular, coarse ones appearing in groups, GLESSULA, PENINSULAR INDIA. 67 or at somewhat irregular intervals. On the last two or three whorls the striation is still coarser, and chiefly on the upper part of each whorl, the lower part being much smoother. Specimens from Poona before me are more slender than those from Bombay, measuring 21 x 7 mm., with 10^2 whorls. The sculptured embryonic whorls show that this species is not related to G. tenuispira. I am much inclined to doubt that the specimens recorded from the Sylhet region are really notigena. They are probably tenuispira. 22. G. CORROSULA (Pfeiffer). PL 12, figs. 5, 6.

Prof. Boettger states that by the study of Mr. Rolle 's speci- mens of G. sumatrana, he sees that G. javanica is identical, and the latter name should be withdrawn. Apparently "javanica" is 'an error for cornea. The original account follows. G. cornea Boettger. (PI. 14, fig. 3.)

Two quite distinct groups of Glessula are represented in West Africa. The group of G. lavigata, has substantially the shell-structure of Indian Glessulae. The shell is smooth throughout (species 87, 88) . In the group of G. paritura the post-embryonic whorls are finely rib-striate (species 89 to 92). Group of G. lavigata. The central teeth of G. lavigata are narrow, not half as wide as the adjacent laterals. There is a well developed but not overhanging cusp. The laterals are quadrate, tricus- pid, with overhanging cutting-points on all the cusps. Middle cusp longer than the basal plates. There are about 8 laterals, then one or two transitional teeth, followed by the marginals, also of the tricuspid type (pi. 15, fig. 9). The jaw (pi. 15, fig. 10) is very minutely plaited, serrate on the cutting edge, at least in places. 87. G. LJEVIGATA (Pfeiffer). PL 14, figs. 9, 11, 12.

Morelet, who was the first to record a locality for this species, thinks that it must originally have been found nearer the coast, as it is unlikely that any earlier traveler had visited the remote solitudes where Dr. Welwitsch found it. The whorls are smooth except for weak growth-striae, and are parted by a linear suture which is transparent-margined below. The fifth whorl appears disproportionately wide. The spire tapers rapidly near the obtuse apex, but much more slowly throughout the greater part of its length. The ex- cision at the base of the columella is not very deep.

The summit is semi globular ; first 1% whorls smooth in adults, but in young shells they show sparse engraved spiral lines; then vertical grooves ap- pear below the suture, short and widely spaced at first, but gradually lengthening and becoming closer, so that at the end of 2y2 whorls they reach nearly to the suture below, and become so close that the sculpture may be described as rib- WEST AFRICAN GLESSULA. 109 etriate, the riblets smooth, rounded, and about equal to the intervals. On the face of the last whorl there are five or six riblets in one millimeter. The riblets weaken or disappear almost abruptly at the periphery of the last whorl, leaving the base and a very narrow band above the suture almost smooth. The columella is formed just as in the Indian Glessulae, being deeply concave, thickened with a white callus, and abruptly, deeply truncate at the base. The shell is translucent whitish under a very thin pale yellow cuticle. A specimen of the ordinary size measures, length 20.3, diam. 8.8, aperture 8.3 mm.; whorls 6l/2. An embryonic shell, shaken out of an adult, is oval, 4.7 mm. long, with 3 whorls. There is a distinct umbilical slit behind the columellar callus (pi. 14, fig. 19). 90. G. BRETIGNEREI Chaper.

The parietal wall is purplish but not black. The aperture is markedly acuminate above. Judging from the description 116 HEMffiULIMUS. and figure, the sculpture is not so strong as in the following form; yet it must he remembered that the sculpture is usu- ally minimized in Reeve's figures of Achatina. H. D. CARUS Pils., n. var. PL 40, figs. 2, 3, 4, 6. The shell is elliptic-ovate with a rather slender spire and obtuse apex; solid and strong. Nearly 2% smooth, convex whorls form the semiglobose embryonic shell. The next whorl is lightly striate, near its termination the surface becomes minutely plicate and spiral grooves appear ; on the next whorl it is closely and finely plicate, the plicaB cut by several (usually 5 to 7) spiral furrows, which appear as if scratched in a plastic surface. On the last whorl the fine plica become weaker, irregular, often more or less obsolete towards the end of the whorl; there is more or less indistinct malleation, and some irregularity due to former growth-arrest periods, marked by dusky streaks, of which there may be one to four or more on the last whorl. The aperture is elliptic-pointed, outer lip obtuse, more or less thickened, expanded or effuse towards the base. Columella arched, usually very deeply, but sometimes only moderately, its lower portion colored like the outer lip; base truncate, parietal callus glossy Hack, overlaid with blu- ish inwardly. Color as follows : (1) Ground-tint yellow, fading towards the apex: (a) brown spots below the suture appearing on the first post- embryonic whorl, becoming broad, more or less fulgurate stripes on the penult, and next earlier whorls; last whorl showing three narrow equidistant bands and an irregular mottling of the yellow ground, elsewhere olive and brown of varying shades; outer lip and lower half of columella edged with vermilion. (6) intermediate whorls of the spire marked with narrow, close, wavy brown streaks; antepenult, whorl with some subsutural spots, last whorl without bands, irregu- larly streaked with dull green on a greenish yellow or light yellow green ground; outer lip and basal half of columella bright ochre.

The first anatomical observations on Partula were by Ferussac, who discovered that these snails are viviparous. He erroneously states that they have no tentacles, only the eye- pedicels. The next work was by Heynemann, who figured the teeth of P. Urata. The following species of Partula were dissected by Dr. C. Semper (Reisen im Archipel Philippinen, Landmollusken, pp. 158, 159) : P. canalis semilineata, recluzwna, Urata (pi. 17, f. 18, jaw), hyalina (pi. 16, f. 21, genitalia), lineata, otaheitana (pi. xii, fig. 21, genitalia), vanikorensis (pi. 17, f . 17, teeth) . P. lineata was probably not correctly identified. In 1875 (Proc. Acad. N. S. Phila., p. 244) Mr. W. G. Binney examined the anatomy of numerous Raiatean species : P. fusca (pi. 19, f. 9, genitalia), citrina, planilabrum ab- Ireviata, umbilicata (pi. 19, f. 7, genitalia), bilineata (pi. 19, f. 10, genitalia), amanda (pi. 19, f. 4, teeth), virginea (pi. 19, f. 8, genitalia, f. 11, jaw), and gracilis, besides several unidentified species. Some of the same information is re- peated in Annals of the N. Y. Acad. Sci. iii, p. 127. I have examined more or less fully P. rosea, P. varia, P. arguta and some unidentified Raiatean species received with- out the shell. We have therefore some knowledge of the soft parts in species of the sections Partula, Leptopartula, Samoana, and Thakombaua, inhabiting the Society, Samoa and Fiji groups. Animal externally like that of Bulimulidce or Helicida; blunt before, the tail long, gradually tapering. There are no pedal furrows, -and the sole is undivided. Dorsal grooves weak, but the genital furrow is well developed. Genital pore behind the right tentacle, as usual. The lafoial processes are rather large. The mantle has very small right and left lobes. The tentacles are as well developed as usual in land snails (pi. 32, fig. 10, P. canalis). Garrett writes: "The examination of the animals of the various species has convinced me that they possess no re- liable external features that will aid in their determination. PARTULA. 157 The coloration in all the species varies from pale cinereous, through all the intermediate shades, to black or dusky slate. The .arboreal species are generally lighter colored than the ground species, and have a more expanded creeping-disk. The animals of P. arguta} annectens, turgida and attenuates, have the ocular tentacles longer and more slender than the other species, and the exudation of mucus is much more copious and more viscid or tenacious than usual, resembling in that respect the same difference as exists between the typi- cal Helices and the arboreal Naninae." The pallial organs are characterized by the short, more or less triangular kidney, -with a direct ureter which does not extend to the 'Collar, and opens by a lateral pore. The peri- cardium is as long as the kidney. The surface of the lung shows no visible venation. It is densely peppered with light dote (probably calcareous) arranged in irregular lon- gitudinal lines. In P. arguta these light dots are present in spots and stripes (pi. 42, fig. 4), but in other species examined they are equally and densely spread over the whole surface. In P. rosea (pi. 42, fig. 5, x 3) the kidney is very short and strictly triangular. According to Semper, that of P. canalis seems to be of the same form. In P. arguta (pi. 42, fig. 4) the kidney is relatively larger, and the pericardium lies parallel to its longer axis. The ureter also is longer. In an undetermined Raiatean species (doubtless of the re- stricted section Partula) the kidney approaches the band- like type (pi. 42, fig. 6), yet it is somewhat triangular, and equal to the pericardium in length. This is probably the prevalent shape of kidney, since Semper mentions that all the species examined by him except canalis had the kidney, "bandformig. " In most of the subgenera the kidney is unknown. The alimentary canal is of the usual four-folded type. There is a fusiform crop (pi. 42, fig. 5). The jaw is very thin and transparent, varying from slightly arcuate to horseshoe-shaped, similar to that of Drymaus and Zaplagius, formed by the union of many narrow delicate 158 PARTULA. plates, which converge towards the middle, so that there are short plates where the two series meet (pi. 42, fig. 1 jaw of P. lirata, after Semper; fig. 2, central portion of jaw of P. gracilis Pse., after Binney). The number of plates on the two sides is unequal, there being in lineata 27.36, in recluziana 34.38, in otaheitana 40.50 according to Semper. The radula is broad. The teeth form thrice bent transverse rows, as shown in pi. 15, fig. 11, a half row of teeth of P. lirata. The central teeth have the usual quadrate basal plates. In P. amanda, P. rosea, P. varia etc. the length of the basal plate is about twice its width in the middle; the middle cusp is long, reaching to or over the posterior border of the basal plate. Side cusps represented by cutting-points only. The lateral teeth are larger, with the mesooone longer, outer cusp well developed with a strong cutting-point (pi. 43, fig. 1, P. varia huaheinensis Garrett; fig. 2, P. rosea Brod.). There are 11 lateral teeth on each side in P. rosea and planilabrum ; 10 in abbreviate, amanda, otaheitana ; 8 or 9 in varia, umbilicata, virginea, bilineata, hyalina, lineata, recluziana, canalis-, 5 in gracilis. The marginal teeth are peculiar in form, having a long, curved basal plate and 3 cusps, the inner largest, the other two directed outward (pi. 15, fig. 8, 13th to 15th teeth of P. rosea) . They are numer- ous, over 120 in P. virginea. The Fijian P. lirata differs from the Society Island species examined by Binney and myself by having the central and lateral teeth shorter and wider, the central scarcely longer than wide. There are 7 lateral and over 50 marginal teeth, the latter of typical shape (pi. 15, figs. 11, 12, P. lirata after Heynemann) . The radula has been examined in numerous species from the Society, Fiji and Samoan Islands, by Heynemann, Binney, and Semper. I have examined it in P. rosea and varia. Genitalia (pi. 43, fig. 5, P. rosea). — The penis is well de- veloped. It is more or less distinctly contracted near the distal end, which is swollen. Internally the lower portion is PARTULA. 159 coarsely wrinkled, the upper portion densely granulose and coarsely plicate. The retractor muscle is terminal. The vas deferens opens below a papilla situated at about the lower third of the granulose portion ; it is therefore not terminal on the penis. It is superficially bound to the penis, to the vagina and the basal part of the spermatheca, then free as far as the upper end of the oviduct, where it is again adnate for a short distance. The ovisperm duct is strongly knotted, as usual. The basal part of the spermatheca-duct is much swollen in P. rosea and P. fused, the distal end tapering; but in P. bilineata (pi. 43, fig. 3, after Binney) umbilicata, virginea, otaheitana and hyalina the spermetheca is oblong, obtuse distally, and seated upon a slender duct. In all the species which have been examined the duct is short. Reproduction seems to be ovo- viviparous. The upper part of the oviduct contains oblong egg-capsules having a cal- careous shell, which lower down in the oviduct becomes dis- solved or is consumed by the embryo. From one to five eggs or young are found in one individual. Free muscles: — In P. rosea (pi. 43, fig. 4). The pharyngeal retractor is free to its proximal insertion. At about the middle of its length the left ocular and tentacular retractor band joins it, and a little farther out the anterior pedal re- tractors branch off. The broad posterior pedal retractor (tail retractor or columellar muscle) remains united far forward with the right ocular and tentacular retractor, which gives off a group of small anterior pedal retractor muscles. The right ocular band passes between the male and female branches of the genitalia. This muscle system differs from that of Achatinella dolei chiefly by the union of the right ocular with the tail retractor. In Achatinella both ocular bands are free. Relationships of Partulidce. This family is one of the most sharply defined in the Orthurethra. By its short kidney, about equal to the pericardium, it differs conspicuously from the Enidce, 160 PARTULA. Ferussacida, Amastridce and Achatinellidx?, all of which have the kidney very long, far exceeding the pericar- dium. For comparison I figure the pallial region of Ena reiniana (Bulimimis reinianus Kob.), pi. 42, fig. 3, x 2. In the genitalia, the Partulida are remarkable for the absence of an appendix, the penis being simple. This organ is pres- ent and highly developed in all the other families. The vas deferens is practically free from the oviduct, its. adhesions being merely superficial. This is a somewhat unusual con- dition, 'and where found it seems to be associated with vivip- arous reproduction. The shell is rather characteristic; in form some Enidce are similar, yet the spirally striate em- bryonic whorls are unlike that family, and are an invariable feature of Partulidclose waved spiral striae. Spire is straightly conic, suture moder- ately impressed. Whorls 5%, convex, the last whorl swollen in the peripheral region except for the space of a third or fourth of a whorl behind the lip, where it is compressed ; this gives a humped appearance to the back of the shell. Aper- ture ovate; lip broad, white, flatly reflexed, thickened with- in; columella broad, with a deep-seated fold above, visible in oblique view. Length 23, diam. 17 mm. Length 21, diam. 16.7 mm.

The upper edge of the subperi- pheral brown band often shows as a thin line above the sutures of the spire; but frequently a mere brown line replaces the band, and is concealed on the spire (fig. 5). In another form of the species, the cuticle is removed in a zone below the suture. This zone may be wide or narrow; the remaining portion of the last whorl — usually half to three- fourths — is covered with greenish or dull brown cuticle. These variations seem to be characteristic of different colonies. The beautifully developed spiral striation is 'Characteristic of all forms. The lip is flatly reflected, thickened at the inner rim, and rather abruptly narrowed near the upper angle. The umbilical crevice is widely open. 3. P. STRIGATA Pease. PI. 30, figs. 8, 12.

Whether the specimens were actually taken on Huapu ("Woapo") or not remains uncertain. Compared with the type lot of Pease 's P. recta, P. strigata is thinner, darker colored, dull brownish instead of pale green, with a narrower flesh-tinted peristome. The two lots seem to be specifically distinct, until studied in connection with a large series from Nukahiva, subsequently obtained, which seem to be partially intermediate. 3a. P. STRIGATA OBESIOR Pils. PI. 30, figs. 11, 14, 15, 16.

White, 'Covered with a very thin straw, cream or brown tinted cuticle, the spire often corneous (fig. 15). c. Busty brown, having a whitish belt below the suture (fig. 16). d. Dark brown (fig. 11).

The Society Islands are wonderfully rich in Partulas. Both species and individuals are developed in profusion, and differentiation of form and color has been carried further than in any other island group, though there has been no great structural divergence. Probably all of the Society species are referable to two stocks, herein regarded as "sec- tions. ' ' These sections may be defined thus : I. Shell ovate, with short spire, composed of 4 to 4% whorls, very thin, fragile and subtranslucent ; color pale and 176 PARTULA, SOCIETY ISLANDS. simple; aperture ample, peristome expanded, not thick- ened. Section Leptopartula, species 7 and 8. II. Shell composed of more than 4% whorls, usually solid, with opaque coloring, but sometimes white ; lip thickened within. Section Partula, species 9 to 50. Up to this time we owe our knowledge of the distribution and variation of Society Island Partulse to Andrew Garrett, whose residence at Tahiti gave him unusual facilities for their study. In the following account I have quoted largely from his writings and except in a few cases, have accepted his esti- mate 01 the rank of the several species and races. In a case like this, where races in all degrees of differentiation abound, the rank to .be assigned to any given race is, in the last re- sort, a matter of opinion. The criterion of intergradation is often difficult of application, as where the racial divergence is expressed chiefly in slightly different tendencies of varia- tion. In Raiatea and Tahaa especially, there seems to be a good deal of intergradation between the races and so-called species. Section LEPTOPARTULA n. sect. Echo HARTMAN, Cat. Gen.

Two species, the most fragile of the genus, compose this sec- tion, which is confined to Huaheine and Raiatea. 7. P. ARGUTA (Pease). PL 24, figs. 14, 15. The shell is narrowly but deeply perforate, short, ovate, extremely thin, fragile, corneous usually with a faint buff tint, and imperfectly transparent. Surface rather glossy, marked with weak growth-lines and microscopic incised spiral striae which are weak on the last whorl but distinct and close on the spire. The spire is very short, conic; whorls 4, convex, the last evenly convex, globose. The aperture is somewhat PARTULA, SOCIETY ISLANDS. 177 oblique, more than half the total length, broadly ovate.

Huaheine: "The metropolis of this very fragile species is in the upper portion of a mountain ravine, on the west coast of Huaheine, where it is rather common on the leaves of low shrubs and ferns. It occurs much more rarely in a neighbor- ing valley south of its specific center. Mr. Pease's habitat 1 Tahiti, ' as given in his list of Polynesian land shells, is decidedly wrong." (Garrett).

"The animal, which is viviparous, has very long, slender, ocular tentacles, long lance-pointed foot, and that portion of the animal occupying the whorls of the translucent shells is beautifully maculated with black and white spots on grayish yellow ground. The shell, which is very uniform in all its specific characters, may be readily distinguished by its very thin pellucid texture, ovate form, abbreviated spire, turgid body-whorl, uniform pale yellow- ish horn-color, thin, slightly expanded lip and large simple aperture." (Garrett). Pease gave the following description. Specimens received from him are before me.

The pale subsutural band gives the shoulder an appearance of angulation, which does not really exist. While the Tahaan forms of the faba type differ but little from Raiatean faba, yet their variation- forms are somewhat diverse, and the minor differences noted above seem fairly 'constant. I have therefore thought it best, in view of the minute specific subdivision of Raiatean Partulae, to give subangulata specific rank. 36a. P. s. AMANDA Garrett. PI. 17, figs. 1, 2, 3. The shell is like subangulata in shape, but it occasionally has a small tooth on the parietal wall. The usual color is pale yellow or greenish yellow, almost white towards the summit, or more or less suffused with fulvous, with a white or flesh-tinted lip. "A beautiful variety occurs which has a wide median reddish chestnut band (fig. 1). A more common variety is found with two narrow reddish chestnut bands" (fig. 2) ; the summit in these is purple-black. "'Chestnut- brown varieties are not uncommon. The rarest variety is fasciated the same as the typical faba." (Garrett}.

PARTULA, RAIATEA AND TAHAA. 239 A subvariety of amanda has been called var. dubia Garrett- (pi. 17, figs. 4, 8) but that name was already in use for a Tahitian form of the otaheitana group. It is yellow with a white spire, white lip, and invariably has a parietal tooth. Some specimens have a chestnut umbilical area, or are some- what suffused and streaked with fulvous, and the apex is pinkish brown. This form is found in some valleys on the north coast. 37. P.

This form differs from P. faba chiefly by having the last two whorls less convex than usual in that species, and the aperture is narrower, more contracted. Moreover it lives. for the most part on the ground, and has its own patterns of coloring, which however do not differ much from the patterns 240 PARTULA, RAIATEA AND TAHAA. of faba and fusca. G-arrett writes that "hybrids between this species and fusca and faba are very frequent." The typical coloration of navigatoria (fig. 9, copied from Reeve) and the synonymous variabilis is yellow, profusely streaked with chestnut, the spire often pinkish. This is the normal or usual form. Other patterns are: Uniform yellow. Not common. Uniform dark chestnut, or with pale apex. Not 'common. The last form, greenish yellow, the base and a subsutural band chestnut, is not uncommon; it resembles typical P. faba in pattern. ' * The parietal tooth mentioned by Pf eiffer, but not alluded to by Reeve or Pease, is not constant, but exists in about two- fifths of the adults. The former author's 'medio subden- tato,' likewise not mentioned by the latter two writers, is simply the lower angle of the small labial sinus. "In shape it varies from ovate to oblong-ovate, as the fol- lowing two measurements will show: Length 25, diam. 13 mm.; length 20, diam. 13 mm." (Garrett). 38. P. FUSCA Pease. PI. 17, figs. 5, 6, 7.

Raiatea: The metropolis of this very variable ground species is in Vaioara valley, on the west coast of Raiatea, the headquarters of P. garrettii and navigatoria. It has not migrated any to the southward, but to the northward it oc- curs sparingly far up in Huaru valley. On the opposite side of the island it is found in Tepua valley, and I took a few in a small ravine more to the southward. The Tepua shell, which is the protea Pse., differs none from his fusca. (Garrett). ' ' Hybrids between protea and the arboreal P. faba are not uncommon, and are usually found adhering to the lower parts of the trunks of trees. "In Vaioara, hybrids between fusca and navigatoria, and between the two former and faba, are so frequent as to be very embarrassing in the separation of the three species col- lected in that valley. Like the Tepua hybrids, all those be- tween the two ground species and the arboreal faba live on the lower parts of the trunks of trees." (Garrett). 242 PAETUL.A, RAIATEA AND TAHAA. Illustrated from specimens received from Garrett. Others from Pease are before me. This snail lives under cover on the ground, and the shell is less glossy than navigatoria or faba which differ from fusca and vittata chiefly by their arboreal habits and brighter shells. The lip is usually expanded more than in vittata, which replaces fusca on the southwest. P. fusca occasionally has a small parietal tooth, but in vittata the tooth is almost invariable in fully adult shells. 38a. P. F. VITTATA Pease. PI. 17, fig. 16. The shape of the typical vittata is oblong-conic, more or less compressedly umbilicated, and the spire, which equals half the length of the shell, has straight outlines. The last whorl is not angular in front of the aperture. The ample, oblong aperture is 'considerably contracted by the intrusion of white callus on the inner margin of the peristome, and the sides are nearly parallel. The peristome is rather thin, widely expanded and usually stained with brownish purple. The white callus does not extend to the upper end of the lip, leaving a shallow sinus. The columella is flattened, not calloused or nodose, and reflected over the umbilicus. The color is whitish, yellowish corneous, fulvous or horn-color, fre- quently with the basal third of the body and a sutural band chestnut-color. Sometimes the apex is black or purple-black. The parietal tooth, though small, is constant, but so far within that it is hardly visible in a front view. Length 23, diam. 13 mm. (fig. 16). Length 24, diam. 12 mm. (Pease). Length 25, diam. 11 mm.

This is a race subsidiary to vittata characterized by its inferior size, smaller umbilicus, which is frequently imper- vious, smaller aperture, and less expanded lip. The parietal tooth is very seldom developed. The banding is similar in the two forms, but occurs rarely in approximata, which dif- fers also in being generally a lighter or darker chestnut-color, though both have similar horn-colored varieties, with brown streaks. The last whorl is usually angular in front, as in var. terrestris. Occurs in greater or less profusion in several small valleys on the southwest part of Raiatea.

Garrett writes: "In the valleys on the southern part of the island (Raiatea), we find a gradual change from the typical P. ap- proximata into the form known as P. terrestris Pease, which latter connects the former with vittata. The range of ter- restris terminates at Opoa valley, on the southeast coast. "At Faaloa, on the east coast, there exists a form, P. cas- tanea Pease, which is intermediate between terrestris and vittata. It is usually chestnut-colored, constantly toothed on the parietal wall, and the fasciation is the same as in the other varieties. It has not spread any to the northward of Faaloa, but occurs more sparingly in a small valley between Faaloa and Opoa." (Garrett). A specimen of castanea received from Pease is figured (pi. 17, fig. 12) . It is absolutely iden- tical with terrestris. 39. P. PLANILABRUM Pease. PI. 18, figs. 1, 2, 3, 4.

The callous rim and * * tooth ' ' within the outer lip are more strongly developed than in P. faba, fusca and their immedi- ate allies. There is an Oblong callous lump on the face of the columella, more or less visible in different examples. The white border below the suture is an important feature of the species, very rarely wanting. P. planilabrum is larger and more elongated than P. bilineata, and the surface is not so smooth and shining. The structure of the peristome is similar in the two shells, but the aperture is more elongate in planilabrum. The parietal tooth is constant in adults but varies in size. The following color-forms are found. PI. 18, figs. 2, 3.

P. plamlabrum is more lengthened and less glossy than bilineata, and the two have not the same cycles of color-forms. P. umbilicata is a still more shortened and globose form. These three species of Tahaa are slight modifications of the ancestral Raiatean P. auriculata stock. Fig. 14 represents Pease's type specimen. Garrett writes of P. bilineata: "It is readily distinguished by its smooth, glossy surface, ovate- conic form, yellowish horn-color, and two revolving chestnut- brown bands, the upper one narrow and subsutural. The subacute apex is sometimes purple-brown and the suture is margined by a narrow, rugose, whitish line.

This arboreal species is obese, solid, not very glossy, with a moderate or quite narrow umbilicus. The lip is not very broadly expanded, but is strongly thickened within, white, flat, often more or less dentate, and is conspicuously excised above.

Length 21, diam. 13.3 mm. P. auriculata has been united by many authors with the totally different P. otakeitana of Tahiti. The erroneous locality "Huaheine" was given by Cuming, who collected the types. As Pease and Garrett have already remarked, P. auriculata was evidently based upon several forms of this group, but the emphasis laid by Broderip upon the flat lip indicates that the form described as P. compacta by Pease is practically typical auriculata. Reeve's Conchologia Iconica, Partula plate 2, figure 11& may be considered the type of P. auriculata. I have figured similar shells, pi. 18, figs. 10, 11. The color is usually light brownish yellow, but it varies to light chestnut in the lots before me. Fig. 9, copied from Reeve's figure of one of the original lot, is unlike the com- pacta I have seen in being banded. Pease's type of com- pacta, now before me, is a typical auriculata in develop- ment of the apertural callosities. In many individuals the "teeth" are less developed, as in fig. 8. 410. P. A. ROBUSTA Pease. PI. 18, figs. 13 to 16. The shell is somewhat smaller than the largest P. auriculata, PARTULA, HUAHEINE. 249 more compactly ovate, very solid, the lip very little ex- panded and very much thickened on the convex face, though less broad than in auriculata, and with less prominent in- ternal callosities, hence the aperture is more open. The parietal tooth is smaller than in auriculata, and often almost disappears. The lip is generally brown-edged, and often a raised callus connects the ends. The columellar lip is seen, in profile view, to be very thick, and the umbilical crevice is narrow. Color-patterns as follows: a. Last li/2 or 2 whorls corneous, copiously streaked ob- liquely with chestnut; the next earlier whorl rich chest- nut, deepening to purple-black towards and at the sum- mit. This is the typical coloration. 6. Yellowish, with some faint brownish streaks, apex pale. Approaches auriculata in form. c. Dark chestnut throughout, with more or less distinct paler oblique streaks on the last whorl. d. Chestnut colored with a broad corneous or yellowish zone above the middle of the last whorl. This pattern also occurs in auriculata. Length 19.5, diam. 11.5, aperture 11 mm. (fig. 14). Length 17.5, diam. 11, aperture 10 mm. P. robusta has not before been figured, but descriptive notes were published by Smith in his catalogue of the Hart- man collection. Types no. 59444 A. N. S. P. 4. Species of Huaheine. Huaheine possesses four species all endemic. Two (P. arguta and annectens) are restricted to two valleys, and the latter, like P. clara, appears to be gradually becoming extinct. Both species are remarkably uniform in all their specific characters, and are related to forms of Tahiti and Baiatea. On the contrary, the other two species (P. rosea and varia) have spread nearly all over the island, and are subject to considerable variation. Neither is closely related to other Society Island species, but a form scarcely distinguishable from varia occurs at Rarotonga. It is worthy of remark that 250 PARTULA, HUAHEINE. dentated species, which are so common in all the islands ex- cept Bora/bora, do not occur on Huaheine. The structure of the kidney raises a doubt as to the sys- tematic position of P. rosea and varia. They may belong in or near the section Samoana rather than to Partula s. str. 42. P. VARIA Broderip.

PARTULA, HUAHEINE. 251 This common Huaheine species is smaller and more glossy than P. rosea, and differs in its range of color- variation. Ac- cording to Andrew Garrett, the type form "is very variable in coloration, and considerably so in size and shape. The smallest form, which = P. pulchra, Pse., gradually merges into the type, and is restricted to the larger of the two valleys called Hamene. The type which equals my huaheinensis and adusta, is usually corneous, luteous, more frequently fulvous, rarely white, and the most abundant variety is dark chestnut, sometimes nearly black with a pale apex and dark or pale lip (fig. 1). Deep chestnut- colored examples, with a wide or narrow central pale band, are not uncommon (fig. 2). The form with an obscure central fulvous band on a pale ground, is rather common (figs. 6, 7). "In the higher portion of Hamene may be found a large form (Mcolor Garr., not of Pease) which is either uniform straw-yellow, or greenish yellow, with or without a dark chest- nut spire. It differs from the typical varia in being larger, more robust, the whorls more inflated and the aperture wider. Specimens from Garrett are figured, pi. 23, figs. 4 and 8. "In a valley named Faahiti, on the northern part of the island, we find in the greatest profusion, associated with P. rosea cognata Pse., a form shaped like 'bicolor,' but smaller and more variable in color than the typical varia. The most common variety is light yellowish, sometimes stri- gated, the lip, and sometimes the base, stained with burnt- brown or violet-brown. Nearly half of the specimens are1 uniform fulvous brown, or chestnut-brown approaching black. The variety with central pale band is also very frequent, as well as the one of a uniform whitish or luteous with white lip. The pale variety with chestnut spire is somewhat rare, besides one with a dark spire and two narrow bands on the body- whorl. A lot of these shells sent to the 'Museum Godeffroy/ were by Prof. Mousson referred to Morelet's P. simplaria, and have been freely distributed under that name. Morelet cites 'Tahiti' as the habitat of his species. His 'apice obtuso rosaceo' and 'sutura albo marginata' do not occur in these 252 PARTULA, HUAHEINE. shells, nor any of the varieties of varia" hence the name simplaria should not be applied to them. Specimens of various color-patterns are figured, pi. 23, figs. 9, 10. The form called P. glutinosa Pf r. is straw colored or pale fulvous, the lip white with a purplish-brown border. It was originally described as from the Solomon Islands. Fig. 11 is a copy of the original figure. A specimen received from Cuming is drawn in fig. 15. "P. perplexa Pse. MS." of H. H. Smith is the same. P. mucida Pfr. was based on the uniform chestnut colored form of varia. A figure of the type specimen in the British Museum is given, pi. 41, fig. 13. 43. P. ROSEA Broderip.

Huaheine: "The headquarters of this beautiful and well- known arboreal species is in a large forest at the head of Hawai bay on the west side of Huaheine. From this region, where they are very numerous, they have spread over many parts of the island. They differ but little in shape in the different localities, except in Faahiti on the north coast, where they (the P. cognata Pease) are smaller, less angulated on the last whorl, and in the total absence of the uniform dark purple-brown and rose-colored varieties which are so com- PARTULA, HUAHEINE. 253 mon elsewhere.

PARTULA OP THE AUSTRAL AND HERVEY GROUPS. The few species of these groups are very closely related to those of the Society Islands, and no doubt are of common derivation. In the Austral Group, Partula hyalina (see p. 180) is found on Tubuai and Rurutu (Oheteroa). No other Partula is known from the group. One island, Rurutu, has been somewhat carefully explored for land shells (see Garrett, Proc. A. N. S. Phila. 1879, pp. 17-30). In the Hervey or Cook's Group, P. hyalina has been found on Mangaia and Rarotonga. P. assimilis Pse., a form very close to P. varia of Huaheine, occurs on Rarotonga. Pease- PARTULA, HERVEY IS. 261 has stated that the Raiatean P. ~kebe is found on Mangaia (Journ. de Conchyl. 1870, p. 401) 'but his records occasion- ally prove erroneous, and this one seems doubtful. 52. P. ASSIMILIS Pease. PI. 41, figs. 5, 9. The shell is narrowly umbilicate, ovate-conic, rather thin; corneous or faintly yellowish-corneous, nearly uniform, but under a lens it appears to be very indistinctly marked with pale brown streaks; the early whorls are sometimes pale brown. 2ys embryonic whorls with the usual subpunctate spiral lines, succeeding whorls finely weakly striate spirally, convex.

This species closely resembles the pale, yellowish form of P. varia of Huaheine, but differs by the thinner, less conic shell, with the spire more swollen, apex more obtuse and the lip is less thickened within. Pease has described a "var. virgulata, shell generally shorter than the typical form, longitudinally streaked with light red; alt. 15, diam 9 mm. Rarotonga." Two specimens out of the Pease duplicates, from a series received from Dr. Hartman, have the summit purplish, like the form of P. varia figured on pi. 23, fig. 4, yet I do not feel certain that they are really from Rarotonga. 262 PARTULA, SAMOAN ISLANDS. IV. PARTITIVE OF THE SAMOAN ISLANDS. The Samoan Partulae are still very imperfectly known, species having been collected only on Upolu and Tutuila. Nothing is known of the species of the largest island, Savii, if any exist there, or of several smaller islands of the group. The known forms belong to four groups, quite diverse in texture and coloration, but two of them are alike in having the umbilicus unusually open. Key to Samoan species. a.

This species differs from P. conica by its longer, more slen- der spire, absence of spiral striae except on the embryonic whorls and base, the darker tint, etc. It is said to be in- variably sinistral, and restricted to the island Upolu. The color is greenish-yellow with more or less chestnut suf- fusion, sometimes darker in narrow streaks. The spire is darker, reddish brown; suture margined with a white line, narrower than in P. conica. The peristome is flesh-tinted, not so broad as that of P. conica, and the columella is gut- tered at its junction with the body. The umbilicus is ample, as in P. conica. Figs. 6 and 7 were drawn from one of the original lot collected by Schmeltz. Specimens measure as follows. Length 28, diam. 17, aperture 16 mm. ; 5% whorls. Length 27, diam. 16.5, aperture 16.3 mm. ; 5y2 whorls. Length 28.3, diam. 16.8, aperture 15 mm. ; 5% whorls. Length 25.8, diam. 15.8, aperture 14.7 mm. ; 5% whorls. A single specimen before me (pi. 32, fig. 8) has a much shorter spire than canalis, not attenuated as that is. The color is dark chestnut, the spire dull dark purple. It is spirally striate below the periphery. Length 23, diam. 15, aperture 13.3 mm. ; whorls slightly over 5. Upolu. This may represent a distinct subspecies. 53a. Var. BICONICA Pils., n. v.

In his descriptions of this species, Gould considered the large, more or less chestnut colored and smoother form later described as P. canalis to be -a form of conica, and he also, by implication, included the dextral form, his words "in- terdum sinistrorsa" indicating that he 'had seen dextral ex- amples. It is obvious that Gould considered the sinistral form to be typical from his selection of sinistral examples for figuring, and from his comparison "resembling Bulimus l&vus in form"; yet his description is composite, the num- ber of whorls referring especially to the larger brown form (canalis) and the description of sculpture to the striate form here considered to be the true conica. Garrett's restriction of P. conica to the dextral form was not allowable under the existing conditions. 266 PARTULA, SAMOAN ISLANDS. One of Gould's figures is copied, fig. 1. Other figures drawn from the same type specimen are given (figs. 2, 3, no. 2687 A. N. S. P.). The whitish spiral lines on this shell are apparently pathologic. This species is distinguished from P. canalis by the white spire of fewer whorls (5% to 5%), the more developed stria- tion of the last whorl and the comparatively larger aperture. In some examples, such as that shown in fig. 5, the spiral striation of the last whorl is hardly visible above the middle. Gould's second locality for this species, "Raraka," is a low island (atoll) of the Paumotu group, where it is prac- tically certain that no Partula lives. li Partula cornea Gld. (upolensis Mss.)

This species is related to P. expansa, but differs 'by its narrower, less deeply penetrating umbilicus, longer spire, and especially by the spiral striation of the last whorl, which was described by Gould (see fig. 11, drawn from below the suture just back of the outer lip). The opaque buff markings appear mostly as oblique streaks along the lines of growth, but they often tend to become trans- formed into spirally descending stripes, especially on the last half whorl, approaching the condition of the further evolved P. expansa. Often the cream tint predominates over the corneous or brown markings, which remain as streaks or spots. PARTULA, SAMOAN ISLANDS. 269 Partula tryoni Hartman (pi. 31, fig. 5) is a zebrina in which the cream-white markings are reduced to mere flecks. While this color-pattern may possibly be characteristic of a local race, it is surely nothing but a form of P. zebrina. I have figured the type specimen (no. 4261 Carnegie Mus.). It was erroneously supposed to be from the Solomon Islands. Partula actor Albers differs in no respect from zebrina. The type figure is copied, pi. 31, fig. 10. 57a. Var. recluziana Petit.

This species resembles P. varia to some extent, but the spire is less produced. Two lots from the Bartman collection are before me: No. 4284 Carnegie Mus. is from "Fortuna, Friendly Is.," coll. by Brazier (apparently Futuna, the type locality). The shell is thin, pale greenish yellow on the last whorl or two, fading to whitish above near the suture, the spire whitish.

The shell is long ovate-conic, rather thin, rimate; white, pale yellowish, pale brown or rather dark liver brown with narrow paler streaks. Surface lusterless. The embryonic shell consists of nearly 3 whorls, the initial half whorl smooth, following half whorl very subtly punctate-striate spirally, spirals on the next whorl fewer, rather separated, and mainly on the upper part ; third whorl with very weak spirals, which at the beginning of the post-embryonic shell become distinct but low cords. These increase in prominence to the last whorl, where there are 8-12 strong spiral cords above the periphery, with small, unequal cords in most of the intervals, and on the base are many smaller unequal cords and threads. These spiral cords extend to the lip-edge, which is crenulated in all but old specimens. The last whorl is somewhat com- pressed laterally -and convex at the base.

The single Fijian Partula has 'been found only on the small islands of the "eastern group," the genus being unknown on the large islands, where Placostylus 'abounds. The rarity of Partula in this archipelago is at present inexplicable. The single species is one of the most distinct of the genus.

The unique type is a "dead" shell, denuded of cuticle, grayish white, but the color is preserved on the parietal wall, indicat- ing a very pale buff ground marked with narrow brownish- yellow streaks; the coloration perhaps intermediate between that of typical P. turneri and P. caledonica. The apical whorls resemble those of P. brazieri, though the second may be slightly more convex. Subsequent whorls are quite convex, and traces of fine, rather spaced spiral striation, just as in P. caledonica, may be seen on the penultimate and next earlier whorls, the last whorl being 'without spirals except around the umbilicus. Oblique growth-wrinkles are rather distinct. The last whorl is compressed laterally and very convex at the base.

While it is closely related to P. caledonica, macgillivrayi, eximia etc., this species is distinct by the absence of color streaks and the persistence of spiral striae over the whole last whorl.

It differs from P. fraterna chiefly by the better developed spiral striation, lower embryonic whorls and shorter spire ; yet it is not improbable that intermediate forms occur.

The embryonic whorls are more convex than in the group of P. turneri, and the apex is more obtuse. It is closely related to P. auraniana 286 PARTULA, NEW HEBRIDES. but differs by the longer spire of decidedly over five whorls, while auraniana has barely five or fewer. The spiral striation is not nearly so well developed in fraterna, and the second whorl is higher. A second example in the type lot is 19 mm. long, but not quite fully mature.

It measures 13 mm. long, 8 wide, aperture 7.3 mm. long, and has 4^ whorls. It is bluish white, the spire pale brown. The columellar nodule, mentioned by- Pease, may be seen in fig. 9, under a lens. While smaller than Pease's type, I think the specimen is probably identified cor- rectly. I suspect 'that P. concinna was based on a stray example of P. tceniata nucleola. The description certainly favors that theory, and the Hartman example figured seems hardly separ- able from that Moorean shell. 79. P. REPANDA Pfeiffer. PL 34, fig. 11.

The shell is long ovate, moderately strong, white under a thin cuticle which is gray on the spire and base, yellowish- brown in the middle part of the last whorl, where there are very faint traces of spiral lighter and darker bands. The spire is rather long, whorls convex; suture well impressed. Just above the suture may be seen an inconspicuous ridge or angle — the periphery of the penultimate whorl. The embryonic sculpture is worn; subsequent whorls have very even and regular spiral striation, which may be slightly weaker on the upper part of the last whorl. Last whorl is convex at first, on the last half becoming flattened laterally; very convex, sack-like, at the base. The umbilical fissure is short but deep.

Habitat unknown (no. 4237 coll. Carnegie Mus.). "Partula laevigata Pfr.," H. IL SMITH, Ann. Oarnegie Mus. i, p. 452, no. 4237. In shape and •sculpture this species resembles Partula re- gularis, but it differs by the very distinctly marginated suture, the less approaching terminations of the lip, the better de- veloped callus within the lip, and the coloration, which seems to be quite characteristic. It will probably be found to be .a species of the Solomon Island or the New Hebrides. This species was in the Hartman collection under the name "P. laevigata Pfr.," but on the label Dr. Hartman expressed the opinion that it was not that species.

P.), measures, length 11, diam. 6.7, aperture 6.5 mm. long. It is similar but has the corneous cuticle entire and the parietal callus weak in 'the middle. There is a narrow slightly prominent though hardly raised girdle at the peri- phery, where the cuticle is more persistent, 'and this is visible above the suture for a short distance behind the aperture. This structure is so weak that it might readily be overlooked, but it is visible in both of the examples seen. The aperture is decidedly oblique in this shell. This species has a shorter spire than the preceding forms and is a little smaller, otherwise they seem to be closely related. VIII.

A slender, acute pale species, of which I give the original description and figures (pi. 36, figs. 17, 18). These, if ac- curately drawn, indicate a shell with longer spire than any I have seen. Port Carteret examples before me received from Cuming (pi. 36, figs. 15, 16) are nearly white with the spire pale flesh-colored. The surface is glossy, with sculpture of growth- wrinkles and extremely fine and close engraved spirals. Above the periphery of the last whorl these spiral lines be- come faint, more or less obsolete. The apex is rather pointed. The last half of the last whorl is compressed laterally, the base saccate. The aperture is vertical, ovate ; the lip narrowly reflexed and thickened within, thin near the posterior angle, the outer margin slightly sinuous. The umbilical chink is rather small.

A large, bulimoid species having much the appearance of a small Borus. Pfeiffer's type, figured in Philippi 's Abbil- dungen (copied in my fig. 9), is the rather obese form further illustrated -by figs. 7 and 8. The embryonic shell is very densely striate spirally but is usually worn in adult shells. The rest of the whorls have distinct spiral striae, which in the typical form are deeply engraved throughout, but on some examples they become rather weak on the last whorl. The ample aperture is dull purplish inside in some examples, white in others. The white lip is reflexed, and a little thickened within. The 'chestnut color of the shell is sometimes varied by a faintly darker line at the periphery. Examples measure : Length 27, diam. 18.3, aperture 16, x 11.8 mm.; whorls 5%. Length 27, diam. 17, aperture 15.5 x 11 mm. ; whorls S1/^. Length 28, diam. 17, aperture 15 x 12 mm. ; whorls 5%. The form called brumalis by Reeve (pi. 38, fig. 10, copied 310 PARTULA, CAROLINE ISLANDS. from Reeve) is somewhat more elongated, yet it intergrades fully with guamensis, judging from examples 'before me (see measurements above). The forms figured by von Martens from the ruins of Nanmatal belong to this more lengthened type. They further illustrate the variation in shape of aper- ture caused by the different degrees of inclination of the columella, and hence have been copied in my figs. 11, 12, 13, 14 of pi. 38. Dr. von Martens gives the size as length 26, diam. 16, aperture 15 x 11 mm. Both Hartman and von Moellendorff have renamed this species, objecting to the name guamensis "inasmuch as this mollusk certainly does not live on the island of Guam, where my friend Quadras collected for more than two months with- out finding it" (Mlldff.) ; but if the name be rejected on that ground, the species should be called brumalis Rve.

It was identified by Dr. Hartman with P. rufa Lesson, but that is a smaller, especially narrower shell. The type specimen was collected by John Brazier "on the banks of the Leila river, Chabroul Harbor, Ouhalan or Strong's Island," according to a letter from Brazier to Dr. Hartman, written at Sydney, June 18, 1885.

The shell of this species is oval, long, with conic spire, a half whorl swollen. The aperture opens on the right side. It is contracted by a thick rim recurved backward, and di- lated at its junction with the columellar axis, a little in ad- vance of the umbilical crevice. It is nearly of the same size and shape as the 0-Taite Partula [P. otaheitana] , but it is constantly -a little shorter and more inflated. The color is pale yellow with two ribbon-like stripes of fawn, one short, surrounding the opening of the umbilicus, the other running around the middle of the large (last) whorl, and covered by the suture on the spire.

This species was 'considered the same as P. suturalis Pfr., of Moorea, Society Islands, by Mr. Garrett in his paper of 1884, but later he doubted the identification, in a letter written to Dr. Hartman. Mr. Brazier, who visited Ualan, did not find Lesson's species (H. H. Smith, Ann. Carnegie Museum i, p. 446). The general appearance of the shell is that of a Society Island species; but the Coquille did not visit the island of Moorea where the forms (P. suturalis, P. taniata) best agreeing with Lesson's description occur, but only Tahiti and Borabora, ob- taining P. otaheitana at the former, P. lutea at the latter place. They were at Ualan in the Carolines on June 15th, 1824, anchoring in Coquille Harbor on the N.-W. side of the island. In view of the general reliability of the locality records in the Zoology of the Coquille, and the imperfection of our knowledge of the shells of Ualan, I think it not improbable that P. lineata may eventually be found there.

The last three whorls have an opaque white 'border be- low the suture. The last whorl varies in the degree of swell- ing, and in small individuals is usually angular in front, at the periphery; base very full and convex. Umbilicus small and deep, more rounded than usual in Partula. The engraved spiral lines are distinct and not very close above the periphery, more crowded on the base. The aperture is oblique, white in- side in the pale, variously colored in the dark varieties. The peristome is white, or in some forms flesh-tinted. The outer lip is expanded, rather heavily thickened within, the callus somewhat abruptly terminating at the beginning of the curve to the upper insertion; columellar lip dilated. Pigs. 2, 3, 5 and 6 represent individuals of the typical P. gibba. Be- sides the typical coloration (a) described above, there are shells with (&) reddish spire and brown last whorl (fig. 2), and others (c) of the typical pale tint and a white spire (fig. 9). These forms occur together in some lots before me. Other forms are: (d) Corneous-white, somewhat transparent, very thin (pi. 39, fig. 11). (e) Drab with the spire dull dark purple, lip fleshy (fig. 7). (/) Lilac, the spire darker, aperture brown within (fig. 8). (g) Light reddish-brown (fig. 5). (h) First 2y2 whorls bicolored, brown and whitish, the rest corneous-yellow, becoming dull purple near the lip. Interior lilac, with a brown streak within the lip, which is flesh-colored (fig. 10). There is considerable variation in the solidity of the shell, and the thickness of the lip-callus. The latter is sometimes perceptibly nodulous, as in fig. 6. To what extent the variations in color and texture are local or racial is unknown. All have a white sutural border. Ex- amples measure as follows : (a) Length 17, diam. 11.3, aperture 9.8 mm. long.

Marianne Is.: Guam (Pease, Quadras). Partula bicolor PSE., Amer. Journ. of Conch, vii, p. 26, pL 9, f. 4 (August 1,1871). The above may be distinguished from P. gibbet,, which occurs at the same locality, in being of smaller size, last w^orl not inflated, and in its color (Pse.). This form inter grades with P. gibba, and should evidently be regarded as a subspecies of that, chiefly distinguished by having the last whorl less swollen than in typical gibba, and by having a callous nodule deep within, on the parietal wall near the columella. This nodule is seen very weakly de- veloped in some examples of gibba. Other supposed differ- ences are even less constant. Pease's original description reproduced above is not good; his figure is copied, pi. 39, fig. 17. The shell is rather solid, with sculpture of spiral lines as in P. gibba. On the last whorl these lines are very fine and close on the base, but a 316 PARTULA, MARIANNE ISLANDS. little more separated above the periphery. The surface is -glossy. The lip may be narrow and nearly uniform in width, .but usually it is rather strongly thickened inside, the callus .abruptly discontinued near the posterior curve. The color • of the lip is quite variable. There is a callous nodule deep within, near the columella, but it is very variable in size. The suture may be marked with a whitish line, but often this is absent. No specimen I have seen has a well developed white band along the suture, such as is usual in P. gibba 'The color-patterns known are as follows: (a) Straw colored or isabelline, with a reddish-brown band above the suture almost to its end, and covering the first 13/2 whorls; outer half of the lip brown, inner rim white. This is the typical coloration (figs. 12). (b) First 2 whorls purplish-brown, the third pale below the .suture with the dark color fading (or the subsutural •pale area may extend nearly to the apex) ; last 2 whorls straw yellow or pale isabelline with faint or distinct brownish streaks; back of lip reddish or yellow; lip narrow, very pale brown; surface rather dull (fig. 18). (c) Same as the last but without brown on the spire; sur- face lusterless (fig. 15, 16). {d) Pale uniform sulphur-yellow throughout, the lip brown- tinted or brown-edged (fig. 14). ^(e) Pale sulphur-yellow, the lip heavily thickened and pure white (fig. 13).

This form was at first supposed to be from New Ireland, but was soon shown to come from Guam. It is a narrowly umbilicate, thin shell, copiously striped with corneous and opaque white, with more or less suffusion of pale lemon yel- low. In the more fully colored examples there are also many olive-yellow lines among the stripes, scarcely visible except under a lens. These lines dilate at the periphery, which therefore, appears to have a faint band. This pattern is shown in fig. 4. Other examples lack the dark lines and peripheral band. The embryonic shell is very densely and distinctly engraved spirally, the lines disappearing towards the apex ; the first whorl is weakly plicate radially. The last whorl is marked with rather widely spaced spiral lines, closer on the base. In the typical form these lines are rather weak. The last whorl is very full at the base. The lip is white, narrowly reflexed, very little thickened within. Specimens measure : Length 19, diam. 11.2, aperture 11 x 7.1 mm. ; whorls 4y2. Length 17.5, diam. 11, aperture 10 x 7 mm. ; whorls 4%. Length 17, diam. 10, aperture 9.5 x 7 mm. ; whorls 4%. Length 16, diam. 9.9, aperture 10 x 7 mm. ; whorls 4%. A form (pi. 41, fig. 2) collected by Quadras is smaller, with a brown band above the suture on the first 2y2 or 3 whorls of some specimens, the spire in others being pale lemon tinted. The last whorl has the typical coloration. The aperture is more or less brown inside in those with a dark summit. The first whorl does not seem to be plicate. 318 PARTULA, MARIANNE ISLANDS.

Rush collected examples much darker in color at Port San Luis d'Apra, Guam (no. 84841 A. N. S.). The last iy2 whorls are striped with cream and dark brown, with a narrow but con- tinuous brown peripheral band. The spire is uniform dark brown, aperture brown within. Sculpture typical. Length 15, diam. 9, aperture 8.8 mm. (pi. 41, fig. 1) . 111. P. QUADRASI Moellendorff. Shell dextral, narrowly and half-covered perforate, rather ventricose ovate-conic, very thin, pellucid, delicately striatu- late transversely, decussated by closely crowded spiral lines; a little shining, pale buff variegated with narrow darker and whitish streaks, sometimes ornamented with two indistinct bands. Spire subregularly conic, the apex somewhat obtuse. Whorls 4, a little convex, separated by an appressed, mar- gined suture, the last whorl quite convex, nearly tumid. Aper- ture rather oblique, oval, a little excised; peristome simple, thin, well expanded, the columella dilated above, recurved, forming a distinct angle, almost channeled, with the parietal wall. Length 15, diam. 10.5, aperture 9x7 mm. (Mlldff.) Marianne Is. (Quadras). Partula quadrasi MLLDFF., Nachrichtsblatt d. Deutschen Malak. Ges. xxvi, Feb., 1894, p. 15. An unfigured species which seems to differ from the small form of P. radiolata in sculpture and by having fewer whorls. It is possibly identical with Ferussac's P. fragilis, a lost species which has not been figured. The description follows : P. fragilis Ferussac. Shell ovate-elongate, perforate, fragile, striatulate, pellucid, reddish; spire obtuse, sutures strongly marked. Whorls 4, the last ventricose, subcarinate, larger than the rest. Aperture ovate, peristome subreflexed. Marianne Is. (Gaudicho). P. fragilis FER., Tableaux Syst. des Anim. Moll. p. 66 (1821).

SNAILS OP OTHER GENERA DESCRIBED AS PARTULAE. Partula acuticosta, consimilis and lamellicosta, Journ. A. N. S. Phila. ix, 113, are errors for Patula a., c. and I. Partula auricula Fer., 1821 = Auriculella. Partula australis Bowdich lS22==Strophocheilus. Partula batavia Grateloup, 1840, = Amphidromus adamsi var. rubiginosus Fulton (Proc. Malac. Soc.

Partula glaber Hartman, Proc. A. N. S. Phila. 1885, p. 205, is Drymceus strigatus Sowb., color-form purus. See MANUAL XI, p. 228. The type specimen of glaber, no. 4291 Carnegie Museum, agrees exactly with the Peruvian shell, but the internal lilac lip-border, though still noticeable, has faded. Partula layardi Bra/., Hartm. is a Diplomorpha,, Vol. xiii, p. 116. Bulimus macleayi Brazier from Yule Island, other islands in Torres Strait, and Queensland, was described as a Papuina in this Manual, Vol. XIII, p. 121. It has been referred by Hedley to Partula (Proc. Linn. Soc. N. S. Wales ix, 1894, p. 387, pi. 26, f. 22, 23) ; the radula figured by him has marginal teeth resembling those of Partula, yet differing by the larger size of the second cusp, whereas in Partula the inner cusp is the larger. The central tooth has no side-cusps. There are 160 rows of 40,6,1,6,40 teeth. If the pallial organs etc., confirm the relationship claimed by Hedley (but which I doubt) this species will form a new genus of Partulidce, char- acterized by the unexpanded, thin and simple lip of the shell, and the absence of the typical apical sculpture of Partula.
