This species is distinguished from B. variolosa by having a 

 well-developed upper palatal plica ; the lower palatal plica is 

 longer and more deeply entering, and the columellar lamella 

 emerges more. Fig. 7 represents an immature shell. 



The specimens from Cariaquita, Venezuela (pi. 29, figs. 11, 

 12, 13) do not differ materially from those of Jamaica. 



Professor Poey's reference can hardly pertain to this 

 species. From Dr. Sterki's notes there can be little doubt 

 that he had tenuidens from Jamaica and Cuba, which he iden- 

 tified as variolosa. It appears to be rather widely distributed. 



3. BOTHRIOPUPA BREVICONUS n. sp. PI. 28, figs. 9, 10. 



The shell is globosely ovate-conic, thin, light ochraceous-buff, 

 the surface densely, unevenly pitted; composed of 41/3 

 strongly convex whorls. The aperture is irregularly semi- 

 circular, oblique, basal and columellar lip expanded, the 

 outer scarcely so. Parietal lamella rather small, curved as 

 seen in a basal view (fig. 10). Columellar lamella small, very 

 slightly ascending inwardly. Lower palatal plica compressed, 

 entering, but short. Upper palatal plica small, tuberculiform. 

 Length 1.5, diam. above aperture 1.15 mm.

Related to B. conoidea, from which it differs by the longer 

 lower-palatal plica and the presence of an upper palatal. It 

 is also a smaller, more delicate and more minutely sculptured 

 shell, with blunter summit and a more globose appearance. 



4. BOTHRIOPUPA VARIOLOSA (Gould). PI. 29, figs. 2, 3. 



Shell very small, ovate-conic, rufous, subperforate, closely 

 indented ; whorls 4-5, swollen ; suture deep ; aperture ob- 

 liquely semioval, armed with a columellar tooth, another on 

 the lip, another lamellar one posteriorly ; lip slightly reflected. 

 Length one-twelfth of an inch (Old.). 



The ovate shell is composed of about 4y 2 convex whorls.
