junction of the lip with the body-whorl; the columella is strongly 
sinuous and twisted, its anterior margin forms a distinct ridge or fold 
and another similar fold is situated at about the middle; the inner 
lip is excavated in the middle and is thickened by a layer of white 
enamel, which is continuous from the outer lip around to the anterior 
margin. There is no operculum. Color white. 
Length, 12™"; greatest breadth, 8"; length of body-whorl in 
front, 10"; length of aperture, 7"; its breadth, 4™™. 
A living specimen (No. 44,646), was taken at station 2,234, in 
816 fathoms, N. lat. 39° 09’, W. long. 72° 03’ 15”. Another specimen, 
but dead, was taken at station 2,217, in 924 fathoms. 
The last named specimen differs from the type in having the nod- 
ules smaller and less prominent on the last whorl, while there are six 
distinct but not very prominent revolving ridges; but the ribs and 
nodules are sufficiently prominent on the preceding whorls. 
This species is remarkable for its solidity and the coarseness of its 
ribs and nodules. It can easily be distinguished from all our other 
shells by the character of the aperture, and especially by the colu- 
mella-folds. 
Marginella Virginiana Verrill, sp. nov. 
Shell very small, rather slender, fusiform, with an elevated spire, 
composed of three to four whorls, regularly tapered, with a subacute 
tip, formed by a small, rounded, prominent nuclear whorl. Suture 
distinct. Body-whorl elongated, fusiform, with the basal part much 
tapered. Aperture small, oblique, narrow behind, wider in front, 
canal a little expanded at the tip. Outer lip thickened within and 
without, usually a small denticle stands close to the posterior sinus. 
Pillar with four thin prominent folds, the posterior one nearly trans- 
verse; the anterior very oblique. Surface and somewhat polished. 
The color is plain, but varies from grayish or yellowish-white to 
cream-color and pale chestnut-brown, rarely slightly flecked or faintly 
banded with lighter and darker tints. 
The largest example from station 2307, in 43 fathoms, is 5"™ long ; 
breadth, 2°6™"; length of aperture, 3"™. Many specimens are more 
slender than this. A small one from station 2265, is 2™™ long; 
breadth, 1™™. 
This species occurred in considerable numbers at station 2272, off 
Cape Hatteras, in 15 fathoms (No. 44,834); also at station 2307, in 
43 fathoms; and at station 2265, off Chesapeake Bay, in 70 fathoms,
