Hab. ? 



This shell was supposed to have been the Murex rarispina of La- 

 marck, but it having been satisfactorily shown by both Kiener and 

 Deshayes that Mr. Sowerby's Murex formosus is that species, I pro- 

 pose to distinguish it by the above ne\v title.

Hab ? 



An interesting species, well-characterized by the fine dark ches- 

 nut-brown cords with which it is encircled throughout at equal 

 distances.

 guattior fuscescentibus subindistincte cingulatd, spinis purpureo- 

 nigricantibus . 



Hab. ? 



This shell approximates to the Murex tribulus, but its characters 

 present an agreeable modification throughout, which may be con- 

 sidered of specific importance. The spines are constantly tipped with 

 black.

Allied to the Murex chrgsostoma in ret^pect to its rufous orange 

 mouth, but of a different colour and sculpture throughout.
