236 PIFFIN. 



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 JPratercula 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.
