Of this wenus, which comprises v its members the largest of ic bi

the North Pacific Ocean ; and six others the seas southward of the equator,

The weight of this species varies from seventeen to twenty pounds, and the expanse

Diomedea gibbosa, Gould in Aun, and Mag. of Nat. Hist., vol. xii. p. 361. 
Face, ear-coverts, chin, abdomen, upper and under tail-coverts white ; the remainder of the plumage very dark 
brown, approaching on the occiput, back of the neck and wings to black ; bill yellowish horn-colour, becoming 
darker at the tip and at the base; feet in the dried specimen dark brown, but doubtless of a bluish grey, iclining 
to flesh-colour in the living bird. 
The above is the description of a specimen in the collection of the Zoological Society of London, to which it 
was presented by F, Debell Bennett, Esq., who had procured it in the North Pacific. It differs from every other 
that has come under my notice in the peculiar swollen and raised form of the base of the upper mandible, which 
moreover advances high upon the forehead. 
585. Diomedea olivaceorhyncha, Gould. 
Diomedea olivaceorhyncha, Gould in Ann. and Mag. of Nat. Hist., vol. xii, p. 361. 
I propose this name for a species, examples of which are wanting to our collections, and of which a bill only 
has as yet come under my notice, It is in the possession of Sir Wm. Jardine, Bart., is 3 inches and {ths long from 
the gape to the tip, of a uni form olive-green, and in form more slender and elegant than that of the other members 
of the genus. The locality in which it was procured is not known, but it is supposed to have been obtained in the 
China seas. 
The last two species were not scen by me in the Australian seas, but are given m order to complete a mono- 
eraph of the Diomedee.
