7. On the Terrestrial Mollusks of the Viti Islands.-Part I. By ANDREW GARRETT, of Huahinc, Society Islands. (Communicated by Mr. JOHN 1-1. PONSONBY, F.Z.S.)

[Received December 8, 1886.1

The Viti Archipelago, which comprises nearly 200 islands and islets, is embraced in an area between 178" 20' W. and 17G" 55' E. long., and between 15" 47'and 19' 13' S. let. The islands are dis- posed in three groups-the eastern, intermediate, a i d western. The former, which is only partially explored, comprises niany small islands, mostly of coralline tormation, which have been more or less upheaved through volcanic agencies. All the land-shells, so far as known, com- prise the same genera of small shells as obtained in the Tonga and Samoa Islands. The middle portion, which includes all the large islands, though imperfectly explored, have so far yielcled many large and interesting species. Besides the same genera which occur in the eastern group, we find the genera Placostglus, Nanina, D@lomrnatina, Pupina, and Lagocheilue. All these genera, which are represented by peculiar species, connect the land-shell fauna with Bustralasia and the East Indies. The latest and most interesting discovery is the occurrence of the Asiatic genus Layocheilus, which was found by Mr. Liardet in Gomea Island. The western or Assawa group,

which is unexplored, will undoubtedly produce many species not found in other parts of the archipelago.

Tho genus Succinen, so widely diffused throughout the Pacific islands, has not been discovered in these islands.

The earliest known Vitian endemic land-shells are Bulimus mallen- tus, B. fulguratirs, and Hel ix nouleti, all described in the ‘ Revue Zoolopique ’ i n 1842, the two former by Dr. Jay, and the latter by Le Guillou. In 1Sl5, Philippi published Helix p f e i f e r i , and Mr. Hinds described Pythia pollex. I n 1846 and 1847, Dr. Gould added several new species, all discovered by the U. S. Exploring Expedition. I n 1855 Dr. Pfeiffer described H e l i x Zudersi ; and six years later Dr. Dohrn added the beautiful Bulimus seemanni to the list of endemic species. I n 1865, Prof. Mousson published, in the ‘Journal de Conchpliologie,’ a complete list of the Viti land and freshwater shells, based on the collections made by Dr. Griiffe and added several new species to the 16 peculiar to the group. I n 1870 Mousson’s second paper appeared in the same Journal, and lie de- scribed 26 new species, all collected by Dr. Griiffe. I n the meantime several new species were published by H. Adams, Crosse, Angas, and Semper.

I n the ‘American Journal of Conchology ’ for 1871, and in the ‘ Proceedings of the Academy of Natural Sciences of Philadelphia ’ for 1873, the writer published descriptions and figures of 20 new species, all personally collected. The latest discovery, so far as I can ascertain, is six new minute species collected by Mr. Liardet, which were published and fignred with their animals i n the ‘ Proceed- ings ’ of the Zoological Society for 1876.

Out of 146 species now recorded 85 are peculiar to the group. The I46 species are embraced in 32 genera, 1 1 of which are operculated.

Genus HELICARION, FQrussac. 1 . HELICARION VITRININA.

Nanina? vitrinina, Liardet, Proc. Zool. SOC. 1876, 1). 100, pl. 5.

G‘ Shell yellow, thin, translucent, perforated, discoidal ; whorls 44, last subangulated, the others slightly convex ; beneath shining and well rounded ; aperture slightly oblique, h a t e ; suture marginate ; peristome thin ; columella slightly expanded over the perforation. Animal black, with mantle covering two thirds of the shell, which it cannot enter a t first.”

‘‘ Found in moist situations under logs, in this respect resembling Vitrinn.” (Linrde t . )

This species, which is unknown to me, was found at Taviuni Island.

‘‘ Animal red ; a protuberance on the back rests aKainst the shell anteriorly. I t piogresses by raising its liead, extrnding the body, and placing the posterior part of the foot down in the form of an arch, la i~ds its body gradually fiorn the head ; and this arch thus appears to recede until the caudal eutretnity is reached. Like N. ? vitrinitm, it cannot a t first recede iuto its shell; and like ’ri’trina strangei of A l i i ~ t r a I i a , it lea\es rnuciis in its track of‘ a brick-red colour. I Iub .

Helix (Trochomoryha) merzianoides, Garrett, Proc. Phil. h a d . Nat. Sci. 1873, p. 257, pl. 3. fig. 7 2 .

A rare species inhabiting Vanua Levu, where I found a few examples adhering to the trunks of trees.

Its large size ('22 millini.), honey-yellow base, chestnut-brown upper turfiwe, which is mottled with radiating lines and spots of a luteoils-white colour, will a t once distinguish it. The upper surface is coloured nearly the same as T. merziana, a Solomon-Island species ; but the present species may be separated by the absence of the basal band, darker colour, the narrower last whorl, and its narrower aperture. 2'. merziana also differs in having the upper margin of the peristome inflected.

Its most essential rliaracters are its rattier small size (12 millini.), depressed trochifurm shape, crowded irregular plicate strize, brownish colour, and pale riiarkirigs. The spire is convexly-conical ; whorle 6, with narrow white margiiis. Base rather flat, corneous, with a reddish-brown band next to the acute white keel. Umbilicus small.

found at Lomaloma, Vanua Balavo. Griiffe subsequently discovered some specimens of l'rochoinorpha in the interior of Viti Levu, which Monsson (in Journ. de Coiich. 1870, p. 122) referred to his 1'. truns- arata, adding additiorlal characters and giving a good figure of the same. On the same page he describes the var. depresso-striata, nhicli latter iq probably distinct and = T.,fessonia, Angas.

Unfortunately I lost a11 my Kantavu specimens of the latter species when shipwrecked, and have only a siugle dead example of T. transarata from Lomaloma, which exactly coincides with Mousson's original description, and agrees with his figure of a Viti Levu shell.

Mr. Brazier (in P. Z. S. 1871, p. 322) adds T. transaratu to the synonymy of fessonia. Schmeltz (in Cat. Mus. Godeff. v. 1). 94, sp. 5939) quotes MOUSSOII'S var. T. depresso-striata as = fessonia, and, judging from the Museum numbers, he does not include the type, which is no. 5235 (see Cat. 110. iv. p. 73), in the synonymy.

I ts small size, depressed conical form, rough irregular plicate stria?, brownish horn-colour with interrupted radiating pale stripes, elevated spire, slightly convex base, and small umbilicus are its most prominent characters.

interior of Viti Levu. I t has the spire more elevated than T. traizsarata, a greenish-

violet colour, the strice strong and irregular, the umbilicus small ; whorls 7, the last one acutely carinated with a compressed, white keel.

10. TROCHOMORPHA CORALLINA.

Trochomorpha (Discus) ludersi, var. corallinu, Mousson, Journ. de Coiich. 1870, p. 123.

I found a few examples of' this species on elevated coralline reefs in forests on Vanua Balavo, and took a large number in similar stations on Mango Island. Dr. Griiffe found it on coral-rocks on Malatta and Tutuna, the latter one of the northern islands of the Tonga group.

I t may he described as follows :- Shell iimbilicated, sublenticular, solid, finely and obliquely striated,

fulvous horn-colour, rarely whitish, with oc without a marginal dorsal and basal dark fuscous band ; spire convexly conoid, obtuse ; suture depressedly margined above ; whorls 5 9 , slightly convex, slowly and regularly increasing, the last one not descending in front, acutely carinated ; base convex ; umbilicus sniall, about one seventh the greater diameter of the shell ; aperture diagonal, subrhomboid-

Major diam. 15, height 6-7 millim. As compared with 1’. ludersi it is srnaller, differs in the ground-

colour, the umbilicus is not so large, and the bands are wider a i d only two in number.

‘( Spiru fusco-nigrescens, strigis transversis, albis, imperfectis, eleqanter ornata, ad basin fuluescens, cum zona peripherica fusca.” (Mousson.)

I t is probably distinct from the Samoan type.

I obtained iiumernus specimens of this species a t Vanua Btilavo, where they were found adhering to the trunks of trees. I t is also recorded from Oneata Island.

Shell with a narrow umbilicus, solid, sublenticular, not shining ; strise very fine, oblique and crouded ; whitish horn-colour, with a single dorsal and basal submarginal chestnut-brown line ; spire de- pressedly cnnoid, obtuse ; suture with a depressed white margin ; whorls 5 ; , depressedly convex, slowly and regularly increasing, last oue not deflected in front, acutely and compressedly carinated, keel white ; base convex ; umbilicus about one eighth the major diameter of the shell ; aperture and peristome the same as in T. corallina.

Major diam. 14, height 6 millim. As compared with T. ludersi it is smaller, paler, has only half so

many linear bands, s t r iz finer and the umbilicus much smaller. T. corullina is of a fulvous colour (very rarely whitisli), the bauds are wider and paler and the suture has not got the white margin ; it is also a little larger and smoother, and lives in a different station.

luteous-corneous, the periphery margined above and beneath with R reddish-chestnut line, the upper one following the whorls of the spire ; suture with a depressed, narrow marginal line ; whorls Gh, slightly convex, rather rapidly increasing, last one not descending in front, acute and compressedly carinated, keel whitish ; base more polished than above, convex ; aperture vi ry oblique, depressed, sub- rhomboid-lunate ; peristome thin, straight above, margins cou- verging, basal portion slightly thickened and gently arched.

Major &am. 20, height 7 rnillim. I ieceived several hundred examples of this very distinct species

from a missionary who co!lected them in Kantavu Island. H e gave no information in regard to its station.

Specimens seut t o the Godeffroy Museum in Hamburg were referred to T. swainsonii, a Society- Island species ; and cxaniples sent to an English correspondent were confounded with T. metcavei , Pfeiffer, a l’hilippiue species. I t is probably the H e l i x (Pidena) planovbis, in “ Dr. James C. Cox’s Exchange List,” which he accredits to Kantavu. The T. planorbis of Lesson was collected by that naturalist in New Guinea, and differs from our shell in being smoller, mottled nith olitaceow, and in having ouly 5 whorls. A careful comparison with the description of T. rnetcavei has convinced me that it caunot be the same as the Kantavu shell. T. swninsonii is smaller, thicker, rougher, much more variable, and the positions of the lineations are different.

I t s large size, depressed form, fragile texture, luteous horn-colour with the chestnut-brown marginal liues, and large umbilicus will readily separate it from any other Vitian species.

This species is restricted to the island of Vanna Levu, where it occurs beneath decaying vegetation. Examplcs inhabiting the interior of the island are larger and much finer than those found in the forests near the sea-shore.

My largest specimens taken in the former location are 66 millim. long, and my smallest (adults) from near the sea-shore are only 46 in length. The shape varies from oblong-ovate to elongate-ovate. I t is solid, white or ruddy beneath a fulvous epidermis, and ornamented with longitudinal dark green waved or zigzagged stripes, which are more or less interrupted. The apical whorls are usually reddish. The aperture and lips are u s u ~ l l y orange-red, and the throat fre- quently whitish. The last two whorls are minutely corrugated. A rare variety occurs with the lips and aperture wholly white.

This very distinct arboreal species has a wider range than any other species inhabiting the group. I t is distributed throughout all parts of Vanua Levu, where I collected numerous examples. I found it also on Rambi, Koro, Taviuni, Gomea, Lanthala, and Prof. Mousson, on the authority of Dr. Graffe, records it from Viti Levu.

I t is a rather thin, oblong-ovate, uniform white, decorticated shell, with a large aperture and widely reflected peristome. The rough surface is not so conspicuously malleated as P. malleatus. There exists a rare abbreviated variety on the west end of Vanua Levu, which exhibits a few olivaceous markings similar to those on the latter species.

Otostomus (Plncostylus) seemanni, Semper, Phil. Landmoll. iii.

This fine large ground-species is confiued to IZandaru Islaud, where it appears to be abundant.

Though subject to coiisiderable variation in size and shape, it may, however, be diztinguished by its rather slender form, whitish horn-colour beiieath a yellowish or olive-brown epidermis, which is sometimes ornamented with waved or zigzagged stripes. The surface, though coarsely striated with lines of growth, is seldom marked by transverse corrugatioiis. The auriculate-shaped aperture is narrow, white, though sometimes tinted with fulvoiis, antl the white lip is considerably expanded and slightly reflected antl frequently con- tracted above. Length from 52-77 millim. Like all the ground- species, it is very frequently decorticated.

This is a190 a terrestrial species, and inhabits Kandavu Island, where it was discovered by Mr. Brazier.

I t is described as a rather solid, cylindrically-fusiform species, with longitudinal rugose s t r k and obsolete snbmalleations. Colour ruddy white, with reddish apical whorls. The epidermis is olivr- yellow, with longitudinal waved wliitish stripes. The last whorl is subcylindrical, compressed on the middle, and the auriform aperture and the widely expanded peristomc nre wliitish. Length 4 3 millim. I have never seen an example of this species.

I’lacostylus koroensis, Sclimeltz, Cat. Mus. Godeff. v. p. 92. Occurs in great profusion on the ground in the ceRtral valleys of

Koro Island, where it is peculiar. I t is very closely allied to the preceding species, which it resembles

in shape and sculpture. Colour corneous or tawny yellow, with a white or luteous aperture and rather widely expanded white peri- stome. I t is very frequently distorted and very seldom exhibits traces of a fulvous epidermis, which is disposed in irregular iongitudinal strips and patches. Examples sent to Mr. Crosse were, by that learned conchologist, regarded as distinct from his B. knntavuensis.

rather thin, the sculpture the same as on P. rugosus, and the colour ruddy corneous or whitish, often with a reddish spire. Though very frequently wholly decorticated, the epidermis, when present, is very thin, light fulvous, and iisually beautifully mottled with green, which is occasionally disposed in zigzag pattern. The aper- ture and lips are more or less intense saffron-yellow, paler in the throat. The columellar fold is not so conspicuous, and is more vertical than in the preceding species. The peristome, though usually simple, is often slightly expanded, particularly so iu the Itainbi shells, some of which have the lip slightly reflected.

Bulzmus novemyyratus, Pfeiffer, Mon. Hel. viii. p. 138. Stenogyru gyrata, Mousson, hlS. in Mas. Godeffroy. 1885. This species, which is distributed over a larger geographical area

than any other species of land-shell, is diffused thrcughout all parts of Polynesia, the low coral-islands as well ns the more elevated qroups, and ranges throughout Melanesia, Micronesia, Australasia, the MO- luccas, Philippines, Guam, Ceylon, Sinm, Cochin China, China, and probably extends its range as far as the east coast of Africa.

Since the pnblication of my paper on the Society-Islqnd land- shelis I have received from Mr. E. L. Laynrd examples of Bulimuv souverbianus and B. artensis, both of which are identical with Polynesian specimens of S. tuckeri.

Through the kindness of Dr. Hungerford, of Hong Kong, I have tieen enabled to compare Pfeiffer’s Bulimus panayensis with B. tuckeri, and cannot detect a single character to separate the two species.

I am strongly inclined to believe that the West-Indian Stenoy,yra auhuln, Pfr., is II. form of the Polynesian S. tuckeri, and was acci- dentally imported with the Tahitian bread-fruit plants nearly a hundred years ago. MM. Crosse and Fischcr (Journ. de Conch. 1863, p. 361) record the West-Indian “Bulimus subula ” from Cochin China, and give a good figure of the same, which latter is, undoubtedly the ubiquitous X. tuckeri. I reproduce their remarks as follows :-

“Cette esphce provient de Saigon et Fuyen-Moth, oh e lk a e‘t6 recueillie par Monsieur Michau, dans les fosscts, dans la terre et sous les herbes. I1 peut senibler trbs-extraordinaire de retrouver en Cochinchine une esphce des Antilles, qui n’a guhre ctte’ signale‘e jusqu’ici qu’b Cuba, A la Jamaique et ii Saint-Thomas. Pour ne conserver aucun doute A son 6gard, nous avons cru deroir soumettre un individu authentique B l’examin de M. Pfeiffer, qni a cre‘d l’espkce. I1 faut dnnc accepter le fait, qui peut-&tre, an reste, seulement un accident d’acclimatation : la petitesse et la ldgkretd de la coquille en question rendent cette supposition vraisemblable.”

I have lately received horn Dr. Hungerford several examples of Stenogyra, labelled “ Opeas subula, Pfr., Hong Kong,” which do not differ from the Polynesian X. tuckeri. I have several specimens of Xtenogyra received from Dr. Gibbons, who collected them in Algoa, South Africa. They were labelled :‘ Stenogyra turriformis, IC~RUSS,” but are much smaller than the latter species, and the identification is questionable. They are of the same size, and coincide very nearlv with S. tuckeri. Bulimus johannius, Morelet, from the Comoro Ielands. can scarcely be distinguished from some forms of the latter species.

This species, which is chiefly confined to the lowlands near the sea-shore, is found beneath decaying vegetation and under loose Etones.

They vary in size, number of whorls, development of strie,
