above named species were placed by Pfeiffer (Yers. p. 118, 

 119, 1855), and H. znnites, Pfr., of Mexico, by Gray (Pulm., p. 

 140, 1855.) In 1865 I described (Ann. Lye, YIII., 157) S'.en- 

 opus Guildingi, from Porto Cabello, Venezuela, and, from in- 

 formation given by Dr. Berendt, there is some reason to be- 

 lieve that at least one species inhabits Mexico. The occur- 

 rence of Stenopus in the Guadeloupe subprovince alone, affords 

 additional evidence of the close alliance of the faunas of that 

 subprovince and of South America. 



Liguus and Macroceramus, mentioned as West Indian forms, 

 are not represented in this subprovince, and Strophia only by 

 Strophia uva, L., in Curagao.* 



Stenogyra has no peculiar species ; Opeas Caraccasensis, Rv., 

 occurs in several of the Islands, and also inhabits South 

 America. Pineria Schrammi, to which I have already re- 

 ferred, is found in Guadeloupe, and P. Viequensis, Pfr., in Bar- 

 badoes, as well as in Yieque of the Porto Rico subprovince. 



There is a diminished number of representatives of Mexi- 

 can and Central American, as well as West Indian forms in 

 the subprovince under consideration. Olandina has only 

 Varicella Guadeloupensis, Pfr., (Guadeloupe), and V. semitarum^ 

 Eang. (Martinique.) 



Spiraxis is wanting and Cylindrella has 3 species, the sub- 

 genus Mychostoma being represented by G. costata, Guild., in 

 Barbados, Gongylostoma by C. collaris, Fer., in Guadeloupe 

 and Martinique, and Tracheliaf by G. Trinitaria, Pfr., in Trin- 

 idad. 



Proserpina, as before mentioned, is confined to the Cuba 

 and Jamaica subprovinces. 



The Guadeloupe subprovince is peculiarly rich in South 

 American forms. Bulimus^ which belongs to the Southern 

 Continent, has of the subgenus Pelecychilus, B. auris Sileni, 

 Born., in St. Vincent, B. auris-sciuri^ Guppy, in Trinidad, and 

 an allied, possibly the same species, (both enumerated in my 

 Catalogue, Ann. Lye, VII., as B. glaber, Gmel.) in Grenada ; 

 of Borus, B. ohlongus, MiilL, in St. Vincent, Tobago, Trinidad, 

 and Barbados, introduced in the latter, from St. Vincent, by 

 the late Rev. J. Parkinson ; of Eurytus, B. aulacostylus, Pfr., 

 in St. Lucia. B. auris Sileni and ohlongus also inhabit French 

 Guiana. 



Several subgenera o^ BuUmulus are represented, viz.: Bry- 

 maeus, Liostracus, Mtsemhrinus, Thaumastus and Leptomerus. 



* In my former paper Tp. 143) I noticed H. pentodon, Menke, of Cura- 

 cao, oveiiook 1 g the remarks of v. Martens CMalak. Blatt., 1859, p. 209), 

 who, with much apparent reason, refers to it as a young example of 8, 

 vr(i iS'f'phia Antonii, Kust., of Berbice, is the only known South Amer- 

 ican species.
