PLEURODONTE BAINBRIDGEI AND OTHER JAMAICA SHELLS. 
BY EDWARD W. ROPER. 
It was the writer’s good fortune, during a recent trip to Jamaica, 
to stumble on the metropolis of the large and interesting land shell, 
Pleurodonte bainbridgei Pfr.,at Mandeville. The locality, a heavily 
wooded hill near the hotel, had been neglected until many hills 
more remote were searched, without revealing more than an 
occasional dead shell. The numerous low piles of limestone frag- 
ments upon the summit were turned over with great success, the 
prizes including several white specimens. The common run included 
black with splendid purple lip, dark brown with purple or brown 
lip, and light brown with lip of the same color. The largest speci- 
men was 56 and the smallest only 42 millimetres long. Only two 
or three specimens were over 50 millimetres Jong, and the lot 
averaged smaller than those in other collections examined by the 
writer. There was no variation in shape, all being low depressed 
conical, with finely granulated surface, and all were banded, even 
the white shells being encircled with a very fine semi-transparent 
line. This does not correspund with the typical white form, var. 
pretiosa, which is proportionately much more elevated. The Man- 
deville white shells differ only in color from their black and brown 
fellows. All variations of color are liable to be found under the 
same rock heap, so that environment is not responsible for the col-
