of West India Land Shells. 361 



9. Jamaiea. — Very niimerous specimens collected by Prof. C. B. Adams, Mr. 

 Chitty, M. Roy, myself, and otliers, have come under my notice. Pfeift'er Mov. 

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

 described by Adams, but lie subsequently corrected the error. Many new species 

 of Cyrlotus and Stoastoma were described by Mr. Chitty in the Zool. Proc. in 

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



10. Portorico and Vi»qne — I received very many of the species of these 

 islands, collected by the late Mr. Blauuer, from Mr. Shuttleworth — also from 

 Messrs. Swift, Riise, Knox, and otheis. 



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

 I am principally indebted to Mr. A. H. Riise, II. Krebs, R. Swift, and II. Ilaiig- 

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

 C basicarivatnTn and C. chordiferinn. 



12. St. Lncia. — ^I am satisfied that tlie information afforded by the late Mr. 

 McMuvray as to the habitat of B anlacostj/lus Pfr., was incorrect. It belongs to 

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



13. St. lliotnas. — Nearly a?l the species were collected by myself in 1852. See 

 my Notes in Co7it. to Coneh , p. 215, ami Annah, vi. p. 74. 



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 t?)e Catalogue, because I am 

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

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

 and other islands, as ■^vcll as of the Continents of America, will doubtless afford 

 many neAV speiies, but I do not anticipate that they will sensibly' affect the con- 

 clusions at which I ha/e arrived with regard to the faunas of the islands. 



Although disagreeing with Pfeiffer as to the nomenclature and synonjmy of 

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

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

 instances have exercised my own judgment as to species, where I differ fi-om him. 

 Mucii 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 345 the nunobers of Inopercnlate and Operculate species which occur 

 in the islands E. and S. of Vieqne 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 Inopevculate, and 4S 

 Operculate.
