A. E. Verrill — Mollusm of the Nev) England Coast. 427 



Station 2265, off Chesapeake Bay, in 70 fathoms, several living 

 specimens. 



This species resembles in form Tectxira galeola Jeffreys, but differs 

 in its sculpture. 



Turbonilla perlepida Verriii, sp. nov. 



Shell long, slender, very glossy, translucent, and snow-white in 

 color. Whorls twelve, moderately convex, with the suture well- 

 impressed, narrow, deep, rather oblique. The upper end of the 

 spire is very slender, regularly coiled, with the apical whorl rather 

 large, prominent, reversed, and strongly incurved. The sculpture 

 consists of about twenty transvere ribs on the lower whorls, which 

 are rounded, not very prominent, and extend across the whorls; on 

 the Tipper whorls these ribs become less numerous and less distinct, 

 but are more or less evident on all the whorls below the nucleus, 

 which is smooth. The aperture is short and broad-ovate, with the 

 outer lip well-rounded laterally and in front ; inner edge somewhat 

 angulated at the base of the columella, which is a little excurved. 

 On the body-whorl the transverse ribs do not extend below the per- 

 iphery, so that the base is smooth. Umbilicus absent or represented 

 by a minute depression. 



Length, 7™'"; diameter, l-S""™; length of aperture, M"^". 



Station 2265, off Chesapeake Bay, in 70 fathoms, one living spec- 

 imen (No. 44,790), 



This elegant species is more slender and delicate, and also more 

 lustrous, than any of the allied forms. 



Turbonilla grandis Verrill, sp. nov. 



Shell very large for the genus, with a long, gradually tapering 

 spire composed of many whorls. Suture a little impressed, shallow, 

 narrow, not very oblique. The whorls are comparatively short, 

 rather flattened, and crossed by slightly raised, rather indefinite, and 

 somewhat irregular ribs, which generally extend entirely across the 

 upper whorls, but fade out above the middle of the body-whorl. 

 The ribs are more regular and more elevated on the upper half of 

 the spire than on the lower half. The surface between the ribs is 

 destitute of spiral sculpture, but is marked by fine and nearly regu- 

 lar lines of growth. The base is smooth and there is no umbilicus. 

 The aperture is short and broad, with an acute angle posteriorly and 

 a decided angle at the base of the columella, which is nearly straight
