Porto Rico. B. portoricensis, no. 5. 



1. B. WEINLANDI (Pfeiffer). PI. 8, figs. 52, 53. 



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- 

 low 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). 



Haiti: near Jeremie (Weinland, Henderson). 



Cyl. weinlandi PFR., Malak. Bl., vii, 1860, p. 214, pi. 2, 1 

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



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

 iana, but distinct by the sutural crenulation 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. 



2. B. KRAUSSIANA (Weinland). PL 8, figs. 46, 47. 



" 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 

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