 Crucibulum auriculatum. Cru,c. testa sjiborbiculari, 

 depressd, radiatim costatd, costis obtusis, irregularibus, 

 interdmn divergentibus vel interruptis, vertice snbacuto,

 Hab. Cumana ; and Island of St. Thomas, West Indies. 



The ribs in this species are not unlike those of C. viola-

 colouring is darker, and is seen within the margin, while 

 there is no indication of rose-violet in the interior.
