I am not clear whether this is, or is not, a distinct species 
from the preceding [F. cerithina]? They seem to me to run 
one into the other! Certain it is, however, that Mr. A. Adams 
identified as F. scabra, indubitable specimens of F. cerithina, 
which had been dredged by Mr. McAndrew at Suez! The sculp- 
ture of the Japan forms appears somewhat coarser, and with 
one transverse stria less.

This is almost certainly one of A. Adams’ species, perhaps 
his F. pupoides ?
