Remarkable for its small size and slender form. Some specimens 

 are much shorter than others, and nearly without the slaty lines ; 

 so that the species appears to be quite variable. (Gld.~) 



Lischke has figured this species. His specimens have four spiral 

 cords on the penultimate, 20-21 on the last whorl. The fifth and 

 sixth cords from the suture are much wider than the others, espe- 

 cially than the adjacent cords. The upper fold on the columella is 

 small, the lower strong and split by a deep groove.; between the 

 teeth the columella is deeply excavated. 



S. FRATERCULUS Dunker. PI. 20A, figs. 53, 54. 



Shell small, solid, ovate-oblong, subcylindrical, transversely, evenly 

 sulcate ; banded and dotted with ashy or brown, with two encircling 

 white bands. Spire conic, terminating in a somewhat obtuse apex ; 

 columella bearing two white folds, the larger, anterior one bipartite, 

 separated by a deep sinus from the smaller, posterior fold. Aper- 

 ture dilated, thickened, in front, the lip acute.

A larger, slenderer shell than B. strigosus Gld., having two white 

 bands, and 30-32 spiral grooves. 



S. ACUTA Philippi. 



Shell sublanceolate, transversely closely punctate-sulcate. Spire 

 acute, two-fifths the total length. Aperture narrow, columella bi- 

 plicate, the upper fold minute, the lower large, bifid.

There are about 5 coarsely punctate grooves on the penultimate, 

 about 20 on the last whorl. Col umellar folds exactly as in T. solid- 

 ula. The specimen is white, quite colorless.
