the columella, the lower being the larger. Operculum 

 horny, thickish, of an oval shape, pointed at the inferior 

 extremity. 



The recent Fasciolarias are not numerous, the East 

 and West Indies, however, furnish several species which 

 are rather handsome shells. The F. Tulipa, which is one 

 of the most beautiful, is not uncommon among the West 

 Indian Islands. In delicacy and beauty of colouring 

 there are l^ew shells that exceed the F. distans when in 

 fine condition. The F. aurantiaca, which we have figured 

 is one of the most remarkable as well as one of the rarest. 

 All the species we know are marine, and furnished with 

 an epidermis.
