Tue short compressed form and suddenly contracted 
extremity serve to distinguish this species by, although 
the furrowed or striated apex may be concealed, which 
it often is. 
Found in Shorne Cliff by Mr. Goodhall, but by no 
means plentiful. 
Westrongly suspect B. brevis and B. penicillatus, and 
also B. digitalis, to be but varieties of one species.
