the teeth of all interlocked ; many were much worn, and_ 
the under jaw was in every instance somewhat longer than 
the upper, and of a white colour. The ribs were thirteen 
pairs, the last pair hanging free. The stomachs were 
examined, and their principal contents were remains of 
fish of various kinds, and in various stages of digestion. 
There were several large skulls of Conger-eels, and a few 
of the vertebre of the Garfish (Belone), which are of a pale 
green colour. There were also a few ear bones of the 
Codfish tribe, a few Crabs, one small Cuttlefish beak, and 
the opercula of several Whelks, but no shells of this 
Mollusc, showing plainly that these Cetaceans have the 
power of crushing and rejecting the shells and swallowing 
the soft parts. 
The following dimensions were taken, as accurately as 
circumstances would permit, from the skin, which was 
flattened out for the purpose, and the measurements taken 
in a straight line representing the vertebre.
