 Hab. ? 



This shell approximates very closely to the Murex Sene- 

 galensis, but I still think with M. Kiener that it may be 

 distinguished as a species ; the horn-like spines are longer, 

 and they are webbed at the base with a delicate lamina, 

 which in the Murex Senegalensis is folded down, as it were, 

 upon the varix. 



Species 101. (Mus. Cuming.)

 versim liratd, liris mmerosis cotiferiis, interstitm mi-

The Senegal Mukex. Shell triangularly fusiform, trans- 

 versely ridged, ridges numerous, close-set, interstices 

 minutely scabrous, with two large tubercles between 

 the varices ; three-varicose, varices round, armed with

Lamarck appears to have omitted mention of this spe- 

 cies, and referred to Adanson's figure of it for the illustration 

 of his Murex angidiferis.
