Lignus and Strophia,ioMTLdi both in Cuba and Haiti, are not 

 present ia Jamaica. 



MoucToceramMs, most numerously represented in Cuba and 

 Haiti, has 1 species only in this subprovince, M. Gossei^ Pfr., 

 found also in Cuba and New Providence. Albers places in 

 Anonia, Gylindrella tricolor, Pfr., and other Jamaica species, 

 and in Lia (both subgenera of Macroceramus), C. Maugeri^ 

 "Wood, and its allies, an arrangement which I am not, as at 

 present informed, prepared to accept. 



Stenogyra has representatives of Opeas and Suhulina, but 

 not of Pseudohalea or Melaniella. 



Of genera characteristic of Mexico and Central America, 

 Glandina, Spiraxis and Gylindrella are represented in Ja- 

 maica. Varicella {G. leucozonias, Walch), subgenus of Glan- 

 dina, has its principal development in Jamaica. The species of 

 Spiraxis, unlike those of the Continent, are small, and belong 

 to the subgenus Euspiraxis. Of Gylindrella^ the subgenera 

 Urocopiis, {G. nohilior, C. B. Ad.) and 'Mycliostoma {G. suhula, 

 Far.) are numerously represented. Gasta {G. elongata, Chem.) 

 is peculiar to this subprovince. 



The genus Proserpina {P.niiida, Sowb., P, pisum, C. B. 

 Ad.) has a greater number of species in Jamaica than in Cuba. 



In this subprovince, as in Cuba, Bulimulus is feebly repre- 

 sented,-!?- Z/os/racw5 by B. erubescenSj Pfr., and Leptomerus by 

 B. immaculatus, C. B. Ad. 



Leptinaria, subgenus of Gionella, has two or three species in 

 South America ; and G. monodon, C. B. Ad., of Jamaica, is, I 

 believe, properly placed in it. 



Orthalicus, as in Cuba, is represented solely by 0. undatus^ 

 Brug. 



There are no species in this subprovince which can be spoken 

 of as European or introduced from Europe. 



3. Haiti. The peculiar forms of Helix in this subprovince 

 belong to the subgenera Plagioptycha {H. loxodon, Pfr.), Eury- 

 cratera (H Dominicensis, Pfr.), Gepolis (H cepa, MiilL) and 

 Garacolus {H caracolla, L ) 



H. Audehardi, Pfr., with its ally H. Luguillensis, Shuttl., of 

 Porto Rico, seem to be vQvy inconsistently placed by Albers 

 in the subgenus Polydontes, of which H. imperator is the type. 

 Odontosagda {S. polyodon, W. and M.), subgenus of Sagda, is 

 peculiar to Haiti. 



Liguns is represented by L.virgineus^ L., which occurs also 

 in French Guiana, and Stropkia {^S. glans, Kust.) has several 

 species in this subprovmce. 



Of Stenogyra, the subgenus Oheliscus has S. tereb aster, Lam., 

 Pseudohalea, S. hasta, Pfr., jDoth found also in Cuba, and Opeas
