Shell fusiform, widest at or near the middle, tapering to a 

 small apex above, much less tapering downward. Corneous, 

 thin, finely striate throughout, the neck distantly, irregularly 

 ribbed. Whorls strongly convex, the last not carinate, its 

 latter half free, and descending in a nearly straight, cylindric 

 and contracted neck. Aperture quite oblique, subcircular, a 

 little piriform, the peristome narrowly reflexed. Axis slen- 

 der, straight above, becoming somewhat corkscrew-like in sev- 

 eral later whorls. 



Length 12.7, diam. 2 mm., whorls 18.

Near B. gundlackiana, but distinct by its somewhat larger 

 size, shorter and less curved neck, more oblique aperture, and 

 the more convex whorls, the last one not compressed or cari- 

 nate below. In the original lot taken by Gundlach, some of 

 which are before me, the first 4 whorls are pale, the next two 

 reddish from the contained viscera, as figured by Pfeiffer. 

 In others from Monte Toro, reddish color is wanting, all the 

 early whorls being pale. 



Gundlach mentions that ' ' a smaller variety, otherwise just 

 like the type, was collected at the plantations Los Hermanos 

 and Sta. Maria, at Monte Toro. A more slender form, mak- 

 ing an approach to B. brooksiana by having the last whorl 

 more prolonged below (but not keeled), was taken at the 

 plantation "Yemen." The species is named for Don. 

 Leoncio Turcas, who furthered Gundlach 's explorations in 

 the district of Guantanamo.
