Shell a quarter of an inch long, and about a third less in breadth, 

 pale rufous with some obscure darker spots on the lengthened side, 

 somewhat oval, produced and a little angular at the cartilage side, 

 tumid in the middle and sloping to the sides ; the middle rib flatten- 

 ed and separated by a fine line : beaks very prominent, not central, 

 giving the shell a considerably oblique outline. 



Montagu has observed of this very elegant shell, that the poste- 

 rior side is somewhat angulated, a circumstance which we believe 

 never takes place in this genus, suppposing this side to mean that 

 which is opposite to the cartilage. Perfect specimens are clothed 

 with short sharp prickles, which appear to be very caducous, as in 

 general they are smooth with a few raised wrinkles on the hinder 

 side.
