Shell short, subconic; body large, about double the length

considerably inflated; surface invested with many spiral, muri- 
cated, regular ridges, which are equal in breadth to the inter¬ 
mediate spaces; the spines are short, semicylindrical, and hollow, 
forming a beautiful fimbriated appearance on the margin of

the columella, with a longitudinal indentation, or subumbilicus, 
behind it, at the base of the shell.
