Hab. New Guinea. 



Chrysorrhos would perhaps be the better name for this species, 

 because all I have seen have the rump and base of the tail yellow, 

 whilst some are not spotted. 



Of this species we have in the British Museum — 



1. Adult female, from the Moluccas, from the Leyden Museum, 

 sent as C. chrysorrhos. Uniform ashy-grey ; face, throat, chest, and 

 beneath the rump and base of the tail yellowish. 



2. Young female, from the south coast of New Guinea. Pre- 

 sented by J. B. Jukes, Esq. Dark blackish-ashy ; head, neck and 

 shoulders paler ; rump and base of the tail reddish-yellow ; cheeks, 

 throat and beneath white ; feet bright red. 



The two sides of this specimen are not coloured alike. The fore- 

 head of the skull is very convex. 



3. Half-grown " male from Darnley Island, brought from the 

 south coast of New Guinea." Presented by J. Macgillivray, Esq. 

 Reddish; back and thighs darker blackish-ashy; cheeks, throat, under

 Uranie, t. 7. 



4. Half-grown " male from New Guinea." Presented by J. Mac- 

 gillivray, Esq. Like the former, but white, with irregular large 

 symmetrical pale reddish spots on body, limbs and tail.

 Guinea." Presented by John Macgillivray, Esq. Like the former, 

 but white, with one very large reddish spot on the hinder part of 

 the back ; two large spots on the hind legs, and an obscured in- 

 dication of a large patch on the shoulders ; the feet red. 



6. Half grown, from the "island of Waygeroo." From M. Ver- 

 reaux. Ashy-grey cheeks ; back with some white spots ; throat,
