mella with a broad callus; canal slightly recurved. Epidermis 
chestnut-color; beneath, white. 
Length nearly 2 inches. 
Much more ventricose than F. I[slandicus, with proportionately 
larger aperture, and more numerous and smaller revolving lines.

Am. Journ. Science, xxxviii. 197. 
Shell large, coarse, turreted; whorls eight, very convex, rather 
ventricose, with distant elevated revolving ribs; on the upper 
whorls, two of these, more prominent than the rest, give them'a 
bicarinated appearance. Suture deep. Incremental striz dis- 
tinct, but otherwise the shell has a smooth and worn appearance. 
Aperture rather less than half the length of the shell, broad-oval, 
and somewhat dilated; lip sharp, and somewhat angulated by the 
prominent revolving ribs; in adults the columella margin covered 
with a callus. Canal short, much recurved. Color faint brown- 
ish horn-color; ribs light chestnut-color. 
Length 24, width 1} inches.

Fusus carinatus, Kiener, Species, t. 19, f. 1. 
Shell large, robust, solid, somewhat ventricose, oval; whorls 
six or seven, obliquely flattened above the shoulder, and with 
stout, coarse revolving ribs; there are about ten of these ribs on 
the body-whorl, gradually diminishing below. On the upper 
whorls, the ribs are reduced to two or three large and coarse ones, 
which give a turreted appearance to the spire; between these ribs 
are smaller revolving lines, and the whole surface is coarsely 
wrinkled by the lines of growth. Aperture ovate; lip festooned 
by the termination of the revolving ribs; pillar lip arched, and 
with a broad callus; beak cancellate externally ; canal short and 
curved. Brownish-white or ash-colored; pearly white within, 
grooves on the lip chestnut-colored. 
Length 2.5 inches. 
This is the /. carinatus of Kiener, but not of Lamarck. It is 
figured by Reeve (Iconog.) as Buc. lyratum, Mart. (Murex 
glomus cereus, Chemn.) from Australia ; but Martyn’s species is » 
certainly distinct from ours.
