228 Mr. E. A. Smith on Mollusca 



As no references are given by Guppy, Brown, Angas, or 

 Kobelt, I have appended a complete list of all the known 

 species, supplying that desideratum, and at the same time 

 indicating the known geographical distribution of each species. 



1. *Vaginula occidentalis (Guilding). 



Onchidium occtdentale, Guilding, Trans. Linn. Soc. 1823, vol. xiv. 

 p. 323, pi. ix. figs. 9-12. 



Hab. St. Vincents, Guadeloupe ; Dominica {Angas and 

 Raniage). 



2. '^Vaginula, sp. 



Six specimens, averaging about three quarters of an inch 

 in length, were obtained by Mr. Raraage, which seem distinct 

 from the preceding species. They are in rather poor, soft 

 condition, and scarcely fit for describing. They are darker 

 above and below than V. occidentalism shorter, apparently less 

 tapering at the extremities, and have the foot as well as the 

 lower surface on each side dotted. The general tint is coffee- 

 brown, varied on the dorsal surface, which does not exhibit 

 a pale median line, with irregular blackish dots and spots. 

 The lower surface, especially the creeping-disk, is paler and 

 is also dark-dotted. The dotting on the foot is down the 

 centre, leaving pale lateral margins. The female orifice is 

 equidistant from the extremities and quite close to the foot. 



3. Oleacina perlucens (Guppy). 



Olandina perlucens, Guppy, Ann. & Mag. Nat. Hist. 1868, vol. i. 



p. 430. 

 Oleacina perlucens^ Pfeiffer, Mon. Hel. vol. viii. p. 324. 



Hah. Dominica {Guppy). 



4. ^Stenogyra octona (Chemnitz). 



Hah. Many of the West-India islands, Panama, Caraccas ; 

 Dominica {Guppy ^ Brown^ Angas, Ramage). 



For the synonymy and references of tliis species see 

 Pfeiffer's Monogr. Heliceorum. 



5. Leptinaria lamellata (Pot. et Mich.). 



Achatina lamellata, Pot. et Michaud, Gal. Moll. vol. i. p. 128, pi. xi. 

 figs. 7, 8; Pfeifler, Mon. Hel. vol, ii. p. 272, vol. iii. p. 623 {Torna- 

 tellina).
