26 AMERICAN MARINE CONCHOLOGY. 



mella with a broad callus ; canal slightly recurved. Epidermis 

 chestnut-color ; beneath, white. 



Length nearty 2 inches. 



Much more ventricose than F. Islandicus, with proportionately 

 larger aperture, and more numerous and smaller revolving lines. 



Newfoundland, etc. 



4. F. TORNATUS, Gould. Fig. 3T. 



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 2J, width 1 inches. 



Newfoundland. 



5. F. DECEMCOSTATUS, Say. Fig. 38. 



Journ. Acad. Philad., v. 214. 

 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 abroad 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.
