of ^Yest India Land Shells. 35 



9. Jamaica. — Very numerous specimens collected by Prof. C. B. Adams, Mr. 

 Chitty, M. Roy, myself, and others, have <:ome under my notice. Pfeiffer Mon. 

 iv. treats Geomelamia Greyava C. B. Ad., as a Cylindrella — it was so originally 

 desciibed by Adams, but he subsequently coriected the error. Many new species 

 of Cyclotus and Stoastoma were descr bed by Mr. Chitty in the Zool. Pioe. in 

 1857, but as they do not appear to have been adopted, I omit them. 



10. Portorico arid Viegne — I received very many of the species of these 

 islands, collected by the late Mr. Blauner, from Mr. Shuttle worth — also from 

 Messrs. Swift, Riise, Knox, and otheis. 



11. St. Croix — For these shells, as well as for those from St. John and Tortola 

 I am principally indebted to Mr. A. H. Piise, H. Krebs, R. Swift, and H. Haag- 

 ensen. Two semi-fossil species of Cyclostoma have been described by Pfeiffer — 

 C. basicarinatum and C. chordiferum. 



12. St. Lucia. — lam satisfied that the infoimation afforded by the late Mr. 

 McMurray as to the habitat of B. anlacostylua Pfr., was incorrect. It belongs to 

 St. Lucia, as originally stated by the Rev. E. Hartvig. 



13. St, Thomas. — Xearly all the species were collected by mj'self in 1852. See 

 my Notes in Cont. to Conch, p. 215, and Annals, vi. p. *J4:. 



14. Trinidad. — From the late Mr. McMurray, and especially Mr. Theo. Gill, I 

 received these shells. 



The names of several islands do not appear in the Catalogue, because I am 

 ignorant as to the species inhabiting them — Dominicn, for instance, from which I 

 have never seen or even heard of any species. Further examination of Haiti, 

 and other islands, as well as of the Continents of America, will doubtless afford 

 many new species, but I do not anticipate that they will sensibly affect the con- 

 clusions at which I have arrived with regard to the faunas of the islands. 



Although disagreeing with Pfeiffer as to the nomenclature and synonymy of 

 some of the West India species, my limits do not permit of reference to such 

 questions. In the Catalogue I have adopted his classification, and in a few 

 instances have exercised my own judgment as to species, where I differ from him. 

 Much labor has been bestowed on the Catalogue, and I would mention that my 

 chief object in publishing it is to show the grounds on which my views as to the 

 geographical distribution of the species generally are founded. 



At page 11 the numbers of Inoperculate and Operculate species which occur 

 in the islands E. and S. of Vieque are stated to be 183 and 50, the species com- 

 mon to more than one island being enumerated as belonging to each. The 

 actual numbers, rectoning each species once only, are 103 Inoperculate, and 43 

 Operculate.
