Varieties of Land and FlumatiU Shells of Jamaica. 11 



6 ; height .75, breadth .26. Some specimens are less robust. 



Habitat, Manchioneal, and the east end of Portland. 



N. B. This shell appears to have escaped the notice of 

 the late Professor C. B. ADAMS, though it was in my collec- 

 tion when he last visited me, in 1851. 



Another beautiful variety seems at the same time to 

 have escaped notice, namely, 



CYLINDRELLA MAUQERI, Var. RAPHININA. Shell raddish- 

 shaped, long and narrow, and of the tessalated variety ; 

 shining ; ground color cream white, with alternate rectan- 

 gular and other spots of very pale reddish ash color ; apex 

 white ; 4th and 5th whorls from the top being rich red 

 brown, and plain. 6th same color, with white tessalation 

 over it. In most specimens apex is not truncated. Apex 

 with slightly convex outline. Whorls 14, scarcely convex, 

 with a slightly impressed suture. Lip thin, slightly 

 reflected. A dark brown band round the outside of the 

 labrum, interrupted by a white keel. Striae of growth 

 scarcely visible under a powerful lens. Divergence about

 shell occurs at Peace River, Manchester, wherein " the 

 narrow, slowly widening, snow-white line next below the 

 suture" Ad. Cont. Conch, p. 163 is much finer. 



CYLINDRELLA MAFGERI, Var. UNICINCTA. AD. Owing, I 

 apprehend, to the absence of good specimens in my cabinet 

 at the moment when Professor ADAMS described this shell, 

 some important features are omitted in his description, 

 (Contrib. Conch, p. 163) which better specimens now 

 allow me to notify. 



Instead of " dingy pale yellow," I should call the ground 

 color a pure opaque dead white over a horn color : all the 

 specimens are more or less tessalated in white and horn 

 colors, so that this variety might properly be placed in 

 Professor ADAMS'S division (e). " The broad dark brown
