gatus, Guppy. Shuttleworth remarks : " differt a 0. asperulo 

 Sow., cui sculptura persimilis, testa magis elevata, anfr. convex- 

 ioribus et colore." 



2. Helicina IIeatei, Pfr. 



Guppy did not collect this species, which is allied to H. occi- 

 dentalis, Guild., of St. Vincent. 



3. Helicina minutissima, Newcomb, M. S. 



I received one specimen in 1855, from Newcomb, and sent it 

 to Shuttleworth, who did not return it and expressed no opinion 



about it. 



4. Conulus yacans, Guppy. 



I refer to my remarks on this species in the list of Trinidad 

 shells. 



5. Helix diminuta, C. B. Adams. 

 Jamaica. — C. B. Adams. Grenada. — Guppy. 



6. Helix perplexa, Fe'russac. 



This was not found by Guppy. It occurs also in the Grena- 

 dines. Pfeiffer (Mon. v, 319) erroneously refers this species to 

 Trinidad. 



7. Ennea bicolor, Hutton. 

 Grenada. — Guppy. • 



8. Bulimus glaber, Gmelin. 



Grenada. — Newcomb, Guppy. 



Guppy remarks (Ann. and Mag. June, 1868), "this differs from 

 the Trinidad shell described by me as P. auris-sciuri in its 

 greater solidity and more ventricose figure, and in being less im- 

 pressed in the middle of the last whorl. Its lip is thicker, and 

 its columellar tooth more prominent. In all these respects, ex- 

 cept the compression of the last whorl, it agrees better with the 

 Brazilian P. glaber than the Trinidad form." 



9. Bulimulus indistinctus, Guppy. Ann. and Mag., 1. c. 



Guppy describes this as probably nearest to B. tenuissimus, 

 Fer., and B. scpuleralis, Poey. It is larger, he says, than 

 either of those species, and approaches B. liliaceus in some re- 

 spects. 



10. Stenogyra octona, Chem.
