Ligvus and Slropliia,^ovindi both in Cuba and Haiti, are not 

 present in Jamaica. 



Macroceram.us, 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 

 Anoma, Cylindrella 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 Cylindrella are represented in Ja- 

 maica. Varicella [C. leucozonias, Walch), subgenus of Gkm- 

 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 Cylindrella, the subgenera 

 Urocoptis, (C nobilior, C. B. Ad.) and Mychostoma [C. sv.lmla, 

 Far.) are numerously represented. Casta (C. elongata, Chem.) 

 is peculiar to this subprovince. 



The genus Proserpnna {P. nitida, Sowb., P. pisum, C. B. 

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



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

 sented, — Lioslracas by B. eruhescens, Pfr., and Leptomerus by 

 B. immaculatus, C. B. Ad. 



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

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

 belitive, properly placed in it. 



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



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.), Cepolis [H. cepia, Miill.) and 

 Caracolus [H. caracolla, L.) 



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

 Porto Kico, seem to be nqvj inconsistently placed by Albers 

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

 Odontosagda [S. pjolyodon, W. and M.), subgenus of Sagda, is 

 peculiar to Haiti. 



Llguvs is represented by L.virginevs, L., Avhich occurs also 

 in French Guiana, and Slropkia [S. glans, Kust.) has several 

 species in this subprovmce. 



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

 Pseudobalea, S.hasta, Pfr., both found also in Cuba, and Opeas
