Inhabits the coasts of Canada. Linnaus. Virguiia. Ellis. 



Full grown shells are five or six inches long, and about half as 

 broad, thick, heavy, and nearly of an uniform reddish brown 

 colour ; it has eight slightly striated whirls separated by a 

 channelled suture, and they are transversely divided by a 

 somewhat coronated keel, the part above which is flattish ; 

 the beak is formed by the gradual contraction of the aper- 

 ture, and is about two inches long. Linnaeus considered M, 

 Granum to be the Larva of this species, which Ellis's figure 

 resembles more than M. perversus, although the whirls ap- 

 pear to be reversed, and this may probably have arisen from 

 an error of the engraver. 



CARICA. 81. Shell with the body-whirl ventricose, 

 and armed on the shoulder with large com- 

 pressed nodules ; aperture dilated, and the
