from that island. The locality St. Lucia rests upon Prof. 

 Tate's identification of shells which subsequently proved to 

 be a distinct species, B. tatei. It was not found there by 

 Ramage, whose shells were examined by E. A. Smith (Ann. 

 Mag. (6), iii, 1889, p. 405), who includes costata on Tate's 

 authority. Bland (Ann. Lye. Nat. Hist, of N. Y., ix, p. 240) 

 reports costata from Anguilla; but this island is so remote 

 from Barbados that confirmation of the record is needed. 

 There is a series of 10 white, slightly translucent specimens 

 (form albida) in the collection of the Academy.

 corneous tint ; sculptured with small, crowded and noticeably 

 oblique strias. Spire truncate, noticeably swollen and en- 

 larged in the middle. Suture well marked. Whorls remain- 

 ing to the number of 9 or 9%, slightly convex, the last shortly 

 projecting forward, detached, having a compressed basal keel

Differs from B. costata by the finer costulation, free last 

 whorl and twisted axis. The latter character also separates 

 it from B. antiperversa. 



31. B. ANTIPERVERSA (Ferussac) . PL 5, figs. 35, 36. 



Shell shortly rimate, turrite, the lower three whorls of 

 about equal diameter, the upper half or more of the shell 

 rapidly tapering to a narrow truncation or an attenuate, en- 

 tire apex; pale brown or corneous-brown, thin, nearly luster- 

 less. Sculpture of rather fine, low riblets, but slightly curved,
