6. B. SALLEANA (Pfeiffer), PL 3, figs. 5, 13, 14, 15. 



Shell cylindric, the upper third or more tapering to a rather 

 narrow truncation ; thin, reddish-brown or pale corneous- 

 reddish. Surface somewhat glossy, closely and finely rib- 

 striate, the striae arcuate and as wide as the intervals. 12 to 

 15 moderately- convex whorls are occupied, but generally sev- 

 eral abandoned ones remain attached, so that the total num- 

 ber ranges from 14 to 18. The last whorl is pinched at the 

 base into an acute, strongly -projecting, whitish keel; it is 

 shortly free in front. Aperture irregularly oval, channelled 

 at the position of the keel, the peristome expanded and re- 

 flexed, angular at the termination of the keel. Internal axis 

 encircled by two equal spiral lamellae, with very finely crenu- 

 late edges. 



Length 26, diam. 4.3 mm., whorls 16. 



Length 25, diam. 4 mm., whorls 20.

Larger than the other species of the section. The dark 

 brown specimens in the series before me are more slender 

 than the pale ones, but there is some gradation in both size 

 and color.

Shell cylindric, the upper third tapering to a narrow trun- 

 cation, or with the spire complete ; thin, light brown or
