194 PETREL. 



Inhabits the Southern Ocean, as well as the Pacific; and M. 

 Ternminck esteems it as a distinct species. 



25— LEACH'S PETREL. 



Procellaria Leachii, Tern. Man. Ed. 2d. 812. 



LENGTH seven inches and a quarter. Bill and legs black ; 

 head and body dull black; sides of the belly and upper tail coverts 

 white, with brown shafts; wing coverts dusky brown; quills and 

 tail black; the tail forked as in the Martin Swallow. 



A bird of this description was met with, not long since, in the 

 Orknies. One of them was killed by Mr. Bullock, in the Isle of 

 St. Kilda; another on the Coast of Picardy, in the cabinet of M. 

 Baillon, at Abbeville. 



This species is said to be not uncommon in the Isle of St. Kilda; 

 that it is rarely seen in the day, but appears after dusk ; at which 

 time it is supposed to feed. It lays a single white egg, in the hole 

 of a rock, or other cavity, in the same manner as the common sort. 



26— DIVING PETREL. 



Procellaria Urinatrix, Ind. Orn. ii. 827. Gm. Lin. i. 5G0.

 bird ; length eight inches and a quarter. Bill nearly one inch long, 

 stout and black, the middle of the under mandible white on the 

 sides ; nostrils partly inclosed in a tube ; irides dusky blue ; plumage 

 on the upper parts of the body black brown ; beneath white, except 

 the chin, which is black ; the skin of that part, and of the throat, 

 loose, serving as a pouch, as in the Frigate Pelican ; the wings rather 

 shorter than the tail ; legs bluish green ; webs black ; spur at the 

 back part wanting.
