BELEMNITES penicillatus. 
TAB. DXC .—Jigs. 5. & 6. 
Spec. Char. Short, compressed, very gradually ta- 
pering towards the superior extremity , near 
which it is suddenly contracted to an obtuse 
nearly central striated or sulcated obtuse point ; 
cavity deep. 
Syn. B. penicillatus. De Blainville , Mem. sur les 
Belemn . p. 89. pi. III. f. 7. Knorr, part 2. 
pi. I* /. 1, 2. 3. & 4. 
The 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. 
We strongly suspect B. brevis and B. penicillatus, and 
also B. digitalis, to be but varieties of one species.
