The shell here figured agrees with Brander’s from 
Barton above quoted. It has generally a coarser appear- 
ance than its congeners and is often larger, sometimes, 
perhaps, four or more inches long. The spire varies at 
the apex, being sometimes very blunt. It is very doubtful 
whether Branders fig. 65, ought to have been retained 
under the same name by him. 
From Barton Cliff, I have also the fragment of a young 
one in the blue clay, from a well dug in Richmond Park 
some years ago.

Similar to the last in general form, but the last whorl 
is ventricose ; the edge of the whorls above the concave 
upper part is generally rectangular, with a row of sharp 
spines upon its angle. The transverse striae are often 
obscure over the upper half or more of the whorl. The 
mouth has a very obtuse angle at the upper part. Var. 
i3 has a greater number of ribs and is less ventricose, fig. 3.
