EXPLANATION OF THE PLATES. 
Plate XXVII. 
Represents the skull of the large seal so many years de- 
posited in the British Museum, from the South Seas. 
Plate XXVIII. 
Shows the skull of a seal shot near the Orkney Isles, by a 
gentleman who went two years in succession for that purpose, 
and afterwards gave the skeleton to Mr. Hunter. This 
animal had been known for 30 summers to come to the same 
rock, and lie basking in the sun ; it had a grey beard. 
Plate XXIX. 
Is taken from the skull of a seal in the Museum of the Royal 
College of Surgeons in Lincoln’s Inn Fields, presented by 
Mr. Chevalier : this proves to have been brought by Mr. 
Kearn, in a Whaler, from New Georgia, near the ice to- 
wards -the South Pole. The circumstance of most importance 
in this communication is, that in all the three skulls the teeth 
differ in form : this may arise from the different kinds of 
food on which the animals lived.
