Inhabits the Mediterranean. Linnaus'^ Rivers of Senegal 

 within reach of the tide. Bruguiere. 



Shell about two inches long and ten lines broad, coated with a 

 dark purpHsh brown epidermis ; a small granulated stripe 

 attends the middle of the whirls, and at the sutures, which 

 are obsolete, there is a row of strong tubercles pointing to 

 the apex; the base is flattish, marked with concentric 

 grooves, and on the body-whirl near its margin there is a 

 double row of small aculeated nodules ; the outer lip is 

 much expanded, and nearly horizontal. The description is 

 so short, and the two figures referred to in the Systema 

 ]Naturae are so unlike each other, that it is impossible to 

 come to any certain decision, but the present shell is most 

 probably the Linnsan M.fuscatus. If, however, the ex- 

 panded lip is the mark, by which the turreted Strombi are 

 to be distinguished from the present division of Murices, 

 this shell should be placed with the former ; but in all re- 

 spects they approach each other so closely, that it is almost 

 impossible to draw any separating line. 



TORULOsus. 151. Shell turreted, very finely stri- 

 ated transversely, with a convex belt at the 

 sutures of the lower, and longitudinal nodu- 

 lous plaits on the upper whirls.
