Shell about three inches and a quarter long, two inches and a 

 quarter broad, and rather more than one inch high ; Gmelin 

 has described the perforation to be round, but it is oval, 

 though not contracted in the middle like that of P. nimhosa, 

 to which this species is very nearly allied, and from which 

 Favanne says it differs in nothing but what may be attributed 

 to the effects of age or climate.
