Different kinds of fish which are too large to be arranged in the 
proper places in the Cases. 
Large shad with a long dorsal ray, from Mexico ; a maigre from 
Guernsey; a sword-fish, from Margate; a flying sword-fish, from the 
Indian Ocean, with two other pikes; and belonging to the same kind 
of fish, one which has been forced through the oak timber of a ship.

it. A conger, an angel fish, a short-nosed bony pike from North Ame¬ 
rica; sharks; the nose of various large saw-fishes; a piraruca, from 
British Guiana; a sturgeon, and a large sting ray.
