250 Zoological Society :— 
Var. albina? 
Cuscus orientalis, Temm. & Gray. 
Males pure white, without any dorsal streak. 
Hab. Islands of Waigiou and Ceram. 
Mr. Wallace attached to the male species this observatioa: ‘the 
claws, soles, and end of the tail nearly white; eats leaves and 
cocoa-nuts (young). Hecalls the male C. orientalis. 
We have specimens of both sexes in the Museum ; a very young 
and adult female from Waigiou, obtained from M. Verreaux in 1856 ; 
and male and female, with two young from the pouch, from Waigiou, 
and a male from Ceram, from Mr. Wallace, in 1859 and 1860. 
In the skull of the female the temporal ridges are separated from 
one another by a wide flat band. 
Temminck, and other authors since his work, have described the 
male of this animal as white, and the female as silver-grey with a black 
dorsal streak ; but we have both sexes of the latter colour. Can the 
white males be an albino variety, and confined to the male sex? We 
have two full-grown males of that colour, one obtained from Leyden 
Museum, said to come from Amboyna, and another from M. Ver- 
- reaux, said to come from New Zealand; they both have the small 
hinder false grinders. 
7. Cuscus ornatus, Gray, P. Z. S. 1860, p. 1, pl. Uxxrv. 
(male). 
Both sexes grey-brown, grisled, and marked with small white 
spots and a distinct dorsal streak ; the ground-colour of the male is 
yellowish-red, of the female dark grey-brown. 
Hab. Ternate and Batchian (Wallace). 
We have a male and three females in the British Museum, all from 
Mr. Wallace—a male from Batchian in 1859, two adult and a young 
female from Ternate, obtained in 1858 and 1859.
