the segment of a circle, the border regularly thickened, receding a 

 little posteriorly, near the suture. Callus on the body whorl narrow, 

 nearly even, but a little swollen in the middle and slightly raised. 

 Columella stout, recurved at the end, with two strong, very promi- 

 nent, equal, spiral folds — tlie anterior one projecting beyond the canal, 

 with the end rounded. Length, 4-2""" ; breadth, S'l""" ; length of 

 aperture, 2-5 """ ; breadth of aperture, -11""", 

 From 110 and 150 fatlioras (localities s and o). 



Torellia vestita Jeffreys. 



This shell in form and size somewhat resembles large specimens of 

 Margarita helicina, but it has a ciliated epidermis resembling that of 

 Veliitina laevigata. The spire is small and low; whorls four, the 

 last large, well rounded, forming the bulk of the shell. Suture deep. 

 Umlnlicus small and deep, somewhat concealed by the reflected outer 

 edge of the columella, which recedes in front and joins the outer lip 

 at an obtuse angle, forming a broad, shallow, anterior emargination ; 

 inner border of the columella a little excavated near the body whorl, 

 slightly swollen in the middle. Outer lip sharp, regularly rounded. 

 Epidermis thick, greenish, with conspicuous lines of growth, finely 

 reticulated by raised revolving lines, along which arise numerous 

 slender, but short, hair-like processes. Shell beneath the epidermis 

 white, nearly smooth. Length, 7*5™"^; breadth, 10™™; length of 

 aperture, 6'"™ ; breadth, 4-5""". 



Only one specimen, dead and inhabited by a Phascolosoma, was 

 found in 1872. Since this, however, during the explorations of 1873, 

 it was dredged by Dr. Packard and Mr. Cooke, in 52 to 90 fathoms, 

 on Cashe's Ledge, ofl:" the coast of Maine.
