THE BIRDS OF AUSTRALIA. 
With many specimens before me I constantly find that the young of the 
one species has been separated as belonging to the other, and also that this 
bird has been known as P. hanhsi, while its juvenile form has been called 
P. desolatus. The history of P. desolatus is here introduced. 
At the same time as he named the Broad-billed Petrel, Latham (p. 409) 
described the Brown-banded Petrel thus : — 
Length eleven inches. Bill an inch long, black with the tip yellowish ; the plumage 
on the upper parts of the body greenish ash-colour, deepest on the crown ; the sides of the 
head, taking in the eyes, and all the under parts of the body, white ; the ridge of the wing 
almost black ; quills and tail dusky ; the last rounded at the end, and tipped with dark 
brown ; the legs brown ; webs yellow ; claws black ; when the wing is expanded there 
appears a dark band from tip to tip, quite across the body. 
Inhabits the Isle of Desolation. In the collection of Sir Joseph Banks. 
Gmelin called this bird Procellaria desolata {Syst. Nat., p. 562, 1789) : — 
Pr. ex virescente cinerea, subtus alba, remigibus caudaque rotundata, obscuris, hac 
apice fusca. 
Brown banded Petrel. Lath. syn. Ill, 2, p. 409, n. 14. 
Habitat in insula desolationis II pollices longa. 
Rostrum nigrum, apice flavicans ; tempora oculorumque area alba ; summitas alarum 
fere nigra ; pedes fusci ; membrana digitos connectens flava ; ungues nigri ; alis expansis 
fascia obscura per omne corpus ab apice ad apicem. 
Bonnaterre {Tabl. Ency. Meth. Orniih., Vol. L, p. 79, 1791) named the 
same bird P. fasciata. 
Kuhl {Beitr Zool. vergl. Anat., p. 143, 1820) accepted Proc. desolata for 
a bird certainly different from Latham’s, and introduced Proc. turtur Banks, 
as attached : — 
Proc. turtur Banks.
