carina, which appears double at the summit, and slightly nodulous 

 where it is crossed by the longitudinal lines. Above the carina 

 there is a rather Avide, sloping, flattened or slightly concave sub- 

 sutural band, which is crossed by somewhat raised, moderately 

 exciirved lamella?, parallel with the lines of growth and with the 

 sinus in the lip; there is also a rather faint revolving cingulus a little 

 below the middle of the band. Below the principal carina there is 

 a rather wide concave interspace, which surrounds the middle or 

 most prominent part of the whorls, and is bounded below by a carina 

 like the upper one, but not quite so strong ; anterior to this there 

 are, on the body-whorl and siphon, numerous similar double revolv- 

 ing cinguli, decreasing in size and becoming closer anteriorly ; of 

 these there are about twelve above the base of the siphon ; the con- 

 cave interspaces between the upper ones are about equal in width to 

 the cinguli. The whole surface is covered by numerous slightly 

 raised, longitudinal lines, which are parallel with the lines of growth 

 and are most conspicuous in the interspaces between the cinguli. 

 The apex, in our single specimen, is badly eroded. The aperture is 

 narrow-ovate, not very large, with a distinct obtuse angle at the base 

 of the columella, which is rather short and nearly straight. The 

 siphon is short and straight, distinguished from the body-whorl only 

 by a slight undulation. The canal is short, straight and rather open. 



Length, without the nuclear whorls, 27"""; breadth, 13"'"'; length 

 of aperture, 13"^"'; its breadth, 5™"\ 



Station 2105, off Chesapeake Bay, in 1395 fathoms (No. 35,704), 

 one dead specimen. 



The single specimen of this species is considerably eroded, so that 

 the sculpture, especially the longitudinal lines, appears more strongly 

 marked than it would in a fresh specimen. Perhaps the double 

 character of the revolving carinae is more obvious for the same 

 reason. They may originally have been more elevated and sharper. 

 The species bears but little resemblance to any other known from 

 our coast, but the character of the sculpture is not unlike B. hicari- 

 nata, but the largest specimens of the latter are pygmies, in com- 

 parison with the present species. 



Urosalpinx Carolinensis Vemii, sp. nov. 



Shell small, pretty regularly fusiform, with an elevated, rather 

 acute spire, which forms nearly one-half the total length of the shell. 

 Whorls six to seven moderately convex, with an impressed suture. 

 The sculpture consists of about twelve rather prominent, stout longi-
