TEREBRA INORNATA, D. Sp. 
Plate xx, figs. 11-13. 
Shell below medium size and very slender, consisting of twelve or 
more volutions; spire attenuated; volutions sloping abruptly for about one- 
third of their exposed surface below the suture, below which point their 
sides are vertical, parallel, and destitute of ornamentation other than fine 
lines of growth, except on a few of the apical volutions; where, when per- 
fect, there are fait vertical ridges; aperture narrow, elongate, forming 
about three-fifths of the height of the body volution at its margin; outer 
lip thin and sharp; columella twisted, slightly excavated on its face, and 
marked by a thickened spiral rib near the base; channel slight. 
A number of this species have been obtained, but are mostly corroded 
and dissolved by the action of water, so that all the upper volutions 
have been destroyed; in which condition they are more rapidly tapering 
and present a less number of volutions. In fact most specimens present 
none of the original surface, except on the lower one or two volutions. It 
differs in its surface characters from any known species, in the sloping of 
the upper third of the exposed part of the volution, and the vertical space 
below, and in want of ornamentation. 
Locality and formation: Obtained from a well-boring at Cape May, N.J., 
at a depth of from 320 to 360 feet. From the collection at Rutgers College, 
New Brunswick, N. J.
