Shell cylindric, the upper half or third slowly tapering to 

 a truncation about half as wide as the greatest diameter of 

 the shell; thin; corneous or somewhat pink-tinted. Surface 

 glossy, closely, finely and regularly rib-striate, the riblets as 

 wide as their intervals, nearly vertical and but slightly 

 curved, alternate riblets strengthened into narrow beads be- 

 loiv the suture, making it denticulate. Whorls but slightly 

 convex, the last obtusely keeled below, very shortly free in 

 front. Aperture oblique, irregularly rounded, the peristome 

 expanded and somewhat reflexed, the outer margin narrower. 

 Axis slender, straight and simple. 



Length 13.2, diam. 3 mm., whorls 10%. 



Length 11.7, diam. 2.6 mm., whorls 10%. 



Length 12.66, diam. 3 mm., whorls 10 (Pfr., type).

Cyl. iveinlandi PFR., Malak. Bl., vii, 1860, p. 214, pi. 2, f. 

 12-15; Monogr., vi, p. 373. CROSSE, J. de C, 1891, p. 145. 



Near B, angulifera Gundl. of eastern Cuba, and B. smitli- 

 iana, but distinct by the sutural erenulation and larger size. 

 A young shell in coll. of J. B. Henderson, Jr., shows the apical 

 whorls to be delicately striate vertically. The deciduous por- 

 tion is quite attenuate, and consists of about 8 to 10 whorls. 

 The radula is very similar to that of B. angulifera, but with 

 lower ectocones. In the proportions and absolute size of the 

 large cusps and basal-plates the two species are identical.

" Shell covered-rimate, cylindric-turrite, truncate, rather 

 thin ; closely and elegantly undulate-costellate, a little shin- 

 ing, whitish-brown, diaphanous; suture slightly sunken, not 

 in the least denticulate. Whorls remaining 13-14, nearly flat, 

 the last shortly free, slightly carinate. Aperture oblique, 

 nearly circular ; peristome white, narrowly expanded through- 

 out, flexuous, continuous. Length (truncate) 16, diam. 3 

 Dim.; diam. aperture with perist. 2% mm." (Weinl.)
