This small species has six whorls, of which the last is as long as 

 all the others together. In texture it is thin and fragile. The sur- 

 face shows under the lens transverse (spiral) striae, formed of series 

 of little, extremely short hairs, which make it dull instead of shin- 

 ing. The color is fawn, interrupted by whitish lines alternating 

 with others of a darker fawn. These lines are broken, not regularly 

 distributed, wanting usually on part of a whorl, reappearing again 

 leaving spaces of a uniform fawn without rays. The aperture is 

 oval, lips pale and little reflexed. 



Moricand's description and the substance of his remarks are 

 given above. No other author has added to them, or in fact seen 

 the shell so far as I can learn. Its systematic position is doubtful, 

 the sculpture being as in Rliinus, but the system of coloring unlike 

 any known species of that group, and the apical sculpture un- 

 known. Possibly a Protoglyptus. 



B. ROCAYANUS (Orbigny). PI. 44, figs. 4, 5. 



Shell lengthened, imper-forate, pyramidal, thin, diaphanous, 

 smooth or at most slightly wrinkled longitudinally ; whitish-gray, 

 ornamented with irregular longitudinal lines of white with others 

 of a reddish-brown color. Spire long, with slightly convex lateral 

 outlines, the apex quite acute. Whorls 9, slightly convex, wide. 

 Aperture oblong, irregular, somewhat auriculate, effuse in front, the 

 margins acute and but little expanded ; columella sharp, spirally 

 twisted. Alt. 24, diam. 8 mill. (Orb.); aperture 9 mill. long. 



Wood.-s along the Rio Grande, south of Santa Cruz de la Sierra, 

 Bolivia.
