FUSUS TORNATUS. 



Fusus tonialus. Gould, Am. Journ. Science, Vol. 33, p. 197. 

 F. iU Id. Invertebrata of Mass. p. 286, fig. 201. 



Description. 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 distinct, 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 most prominent revolving bands ; in adults, the inner margin covered with a callus. 

 Canal short, much recurved. 



Color. Soiled white, of faint brownish horn-color ; ribs light chesnut-color. 



Length, 2' 5. Width, 1-25. 



This large Fusus has hitherto only been obtained from the stomachs of codfishes. Dr. 

 Gould has little doubt but lhat it is the M. despectus of Linneus ; but as another shell 

 is now universally received under that name, he thinks it more judicious to give this a new 

 name. If the F. anliquus of Pennant is intended by the same shell, no two species can be 

 more different (See Pennants British Zoology, Vol. 4, p. 282, pi. 81). I am unacquainted 

 with the F. tornatus of Gould, except through his description and figure, which I have 

 adopted. 



FUSUS BAMFIUS. 



PLATE XXXVI. FIG. 339. - 



Murtx bamjius. Montagu, Test. Brit. Supplement, p. 117. 

 Fusus id. Gould, Invertebrata of Mass. p. 289, fig. 198. 



Description. Shell small: whorls six, rounded; spire elevated; suture deeply defined; 

 from fifteen to twenty sharp vertical folds ; aperture rounded, less than half the length of the 

 shell, ending in a curved canal half the length of the aperture ; lip sharp, direct or reflected 

 according to age. 



Color, light brownish ; folds whitish or brownish with age ; aperture brown. 



Length, 0-5. Width, 022. 



Found in the stomachs of fishes, and on both shores of the Atlantic. I only know this 

 species through the description and figure given by Dr. Gould. 



(EXTRA-LIMITAL.) 



F. bicolor. (Say, Jour. Ac. Sc. Vol. 5, p. 215.) Shell small, short, fusiform ; beak and spire subequal. 

 Whorls 5, convex, with abrupt undulations near the suture, almost rising into arched scales. Sur- 

 face sculptured with small revolving grooves, of which there are 20 - 30 on the body-whorl : suture 

 deeply impressed ; aperture diminishing to the beak. Color, lower half of body-whorl tinged with 

 rufous. Length, 0*45; width, 0*25. Florida.
