the rump grey, very broad whitish tips to the tail-feathers, and in 

 the lower breast, belly, and under tail-coverts being; grey. 



One of the specimens is a male, the other a female ; if no con- 

 fusion exists, the female is a trifle larger than the male. The colours 

 are much alike in both, but in one (male) the secondaries have their 

 outer webs brownish black, with very narrow white edgings. The 

 first primary in one of the specimens (male) abruptly attenuated, 

 in the other more gradually so. The oth and 8th primaries are 

 broad and obliquely notched at the tips, as in Ducula, with the 

 outer web longer than the inner. 



Descr. Head and upper neck white ; lower neck and chest 

 whitish cinnamon; mantle slate-black; lower back greyish black ; 

 rump and upper tail-coverts clear grey, the latter inclining to 

 whitish. Lower parts ashy grey, separated from the chest by a 

 broad black band on the lower breast, sharply defined against the 

 chest. AVings slate-black, lower surface of the quills grey, the 

 coverts more greyish brown. Tail slate-black, with an apical 

 greyish-white band about one and half inches in breadth ; under 

 surface of the tail clearer grey ; under tail-coverts whitish. Bill 

 (in skin) light-coloured, the tips yellowish, feet reddish. 



Hah. The two specimens of this bird were shot while with a 

 flock which was seated feeding in a Bonjon tree (a> sort of Fieus). 

 They were never seen except in the region near the sources of the 

 South Alligator River in Arnhem Land. Their flight was very 

 noisy. Their food consists mainly, according to nati\'e report, of 

 the fruit of the said Bonjon tree, the figs of which are not bigger 

 than the berries of the mountain ash.

One specimen, adult female. Roebuck Bay, North-west Australia, 

 20th November, 1895, 



Length of wing 378-380 millim. ; tail 244 ; culmeu 40 ; genys 

 26. 



The only specimen secured is a female. It differs from 

 the females of the larger species (C. banJcd and macrorhynchus) 

 in being wholly black (bluish black above, more greenish below), 

 without spots or bars. The tail resembles that of the female of 

 the larger species, the feathers having the coloured parts mingled 

 with yellow and scarlet ; the lower wing-coverts are spotted. The 

 bill is blackish, with paler margins. 



The question as to w^hether the nearly-allied forms of black 

 Cockatoos — 0. hanJcsi (Lath.), 1790, C. macrorhynchus Gould, 1847, 

 and C. stellatiis, Wagl. 1832 — are to be regarded as distinct and 

 separate species, does not appear as yet to have been cleared up. 



The University Museum at Christiania possesses sevei'al speci- 

 mens of the larger forms, three of them having been obtained in 

 Queensland' by Dr. Lumholtz in June 1882 (two males and a 

 female).
