BuccinuM WHEATLEYI. 
PLATE VII. FIG.162. Maaniriep. 
(STATE COLLECTION.) 
Description. Shell minute, small, ovate-subcylindrical. Whorls six, nearly flat, or at most 
very slightly covex, with a small and distinct suture : surface smooth, with no revolving lines. 
Aperture narrow, sublinear, with a small notch above and a short canal beneath. Body-whorl, 
on its lower portion near the canal, has from eight to ten minute impressed revolving strie, 
becoming more distant above. Lip simple, thin, with a ridge of minute teeth within its inner 
edge, which are entirely wanting in the young. Callus on the columella elevated, not much 
reflected. 
Color. Light horn, with numerous undulated vertical reddish dilated lines. 
Length, 0+23; of aperture, 0-1. 
These shells were dredged by Mr. Charles M. Wheatley, from the harbor of New-York, in 
five fathom water, opposite Staten island. It is closely allied to B. lunatum, but appears 
to differ by the absence of the subsutural revolving line, and the revolving colored lines: the 
revolving lines at the base are more numerous and distinct.

The colored revolving lines, in the specimens on our coast, are not of common occurrence. 
They are occasionally larger than the dimensions stated above. I have seen them, in the 
collection of Dr. Stillman, 0*8 long. ‘The young have the body-whorl much dilated, and the
