 Shell an inch, or sometimes two inches long, and the length, 

 breadth, and height are about in the proportions of three, 

 two, and one ; it is elegantly cancellated with unequal longi- 

 tudinal narrow ribs and transverse striee crossing over them ; 

 the margin is not even, but somewhat arcuated, and strongly 

 crenated on the inside ; the colour is pale dull brown, or 

 greenish or yellov.ish white, sometimes spotted or marked 

 with one or t\^'o brown concentrical rings, 



ATRiCAPiLLA. 93. Shell ovate, cancellated, with 

 the longitudinal ribs nodulous and alternately 

 smaller; summit somewhat lateral, and the 

 inner margin entire.

Inhabits the coasts of Barbadoes. Lister. 



This shell in shape resembles P. Grccca, with which it has been 

 confounded by Gmelin, but the length rarely exceeds an 

 inch, and it differs in having the larger and smaller ribs re- 

 gularly alternate, and the inner margin very nearly entire ; 

 the colour is dull green or olive, with the larger ribs white, 

 and the perforation at the summit is, I believe, always sur- 

 rounded both inside and out with a black ring.
