Bulimus nichollsii Nob.—Quite common on road from Roseau 
to Rosalie; 2000 feet. 
Stenogyra octona Chemnitz.—Abundant everywhere. 
Tornatellina antillarum Shuttleworth.—Sparingly at about 500 
feet. 
Succinia approximans Shuttleworth——Not common; 300 feet. 
Succinia rubescens Deshayes.—Not common ; 300 feet. 
Amphibulina patula Bruguiere—Not common; on bananas at 
Laudat ; 2000 feet. Shell rather larger and more corrugated than 
the St. Kitts specimens. 
Amphibulina tigrina Lesseur.—Rare, 1000 feet on bananas. I 
have not seen A. pardilina Guppy, but fancy it may prove this. . 
Cyclophorus schrammi Shuttleworth (?).— Quite common at 
1500 feet. I can see no difference between this and specimens of 
species. 
flelicina platycheila Muhlfeldt. Not common; 800 feet. 
Flelicina rhodostoma Gray. Not common; 1500 feet. 
Flelicina fasciata Lamarck.—Not rare; 800 feet. 
fTelicina antillarum Sowerby. Common everywhere, but most 
abundant in the lower slopes. 
Bland (Ann. Lyceum, Vol. x, 1872) quotes a letter from Dr. W. J. 
Branch, of St. Kitts, to the effect that Amphibulina patula is un- 
able to contract the entire animal within the shell, but expresses 
his doubt as to the truth of this observation. I have frequently 
seen the animal completely contracted within the shell in living 
specimens, although it is not its usual habit even when alarmed ; 
if thrown into alcohol or glycerine, it immediately withdraws the 
whole body into the shell. 
In giving the altitude at which the different species occur, I 
mean, that so far neither Dr. Nicholls nor myself have found 
them at any less elevation. Further search in which Dr. Nicholls 
is now engaged will undoubtedly extend their range, but I am 
quite confident that none of the species will be found to vary ma- 
terially from these figures in their distribution as to elevation.—
