characteristic, it is entire.

Tue reticulated surface is produced by a number of 
longitudinal sharp ridges, crossed by transverse chords 
placed at about the same distance from each other, and 
equally elevated with the ridges; at the points of their 
intersection they are raised into short angular spines ; 
the whorls are very round, the last one suddenly 
drawn out into the beak, which, though not long, ap- 
pears to be more taper in the individuals before us than 
in those Brocchi described. The lip is thickened and 
furrowed internally. Length three times the width. 
These specimens, which are smaller than the Italian 
ones, are from the Crag at Malden; they are in Mr. 
Parkinson’s cabinet. It is remarkable that the columella 
is wanted, or eaten out, a circumstance I have observed 
in some recent shells.
