 costulatiou, coarser and more distant on the apical whorls, less 

 apparent on the last ; colour very light sienna ; spire high, 

 turreted, sides flat, apex small ; whorls 8, sides rounded, the ante- 

 penultimate the largest, the last ascending, constriction just 

 behind the aperture ; aperture vertical, oval ; peristome closely 

 double at base at right angles to the axis ; coliimellar margin sub- 

 vertical, the tootli not at all prominent, blunt and rounded.

"This shell is very like B. e.rilis, the constriction, ho\Aever, is 

 much more deiined ; there is no spiral striation on the surface of 

 B. exilis, and there is great difference in the form and size of the 

 columellar tooth. Its abnormal form serves to characterize 

 D. exserta well, and it may be compared in this respect to I), uico- 

 harica." {Godivin- Austen.)
