26 AMERICAN MARINE CONCHOLOGY. 



mella with a broad callus ; canal slightly recurved. Epidermis 

 chestnut-color ; beneath, white. 



Length nearly 2 inches. 



Much more ventricose than F. Islandicus, with proportionately 

 larger aperture, and more numerous and smaller revolving lines. 



Newfoundland, etc.

■ 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 striae 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 2^, width 1^ inches. 



Neicfoundland.

 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 F. 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.
