"B. turriformis 'and B. linearis are closely related to one 

 another, but the last is comparatively much longer and nar- 

 rower, almost cylindric, distinctly striate, has 10 whorls, and 

 the mouth is but little lengthened. The strias (which are vis- 

 ible only under a lens), as well as the right margin of the 

 peristome, are arcuate" (Krauss). 



Sturany remarks that this species has a thread-like suture, 

 other characteristic marks being the glossy surface, the num- 

 ber of whorls (10), and the size, about 12.5x3 mm.
