PUFFIN. 
Cheeks and throat pale grey, when viewed from 
the side appearing as a round pale patch on the side 
of the head ; the colour is darker at the sides of the 
chin and immediately behind the eye, where the 
line separating the auricular feathers from the others 
is apparent ; eyes protected by a large scale above 
and below, that above triangular, that below oblong ; 
crown forming a band to the occiput, collar round 
the throat, upper parts, wings and tail, black, on 
the crown and collar tinted with grey, under parts 
pure white. The bill occupies the whole face of 
the bird, is very much compressed, and is traversed 
on the maxilla by three, on the mandible by two 
furrows; the colours are bluish grey and orange- 
red; the sides of the mouth are furnished with 
a corrugated orange-yellow skin. Feet and legs 
orange-red. 
The Fratercula glacialis , Leach, is a good spe- 
cies; Mr. Gould has been so kind as forward a 
specimen for our examination ; it differs in its larger 
size and proportions, different colour of the bill, 
brown colour of the crown, form of appendages over 
the eyes, and in the black colour coming up to the 
chin, leaving no white space between it and the 
bill.
