Dr. J. E. Gray on the Genus Cuscus. 247 
scribed as C. maculata may be albivo varieties or half-domesticated 
varieties of them, for the natives of some islands are said to breed 
them. 
As I have not the power of examining the skulls of all the speci- 
mens, I have arranged those in the Museum provisionally under 
these two names, taking them as they designate the general colour 
of the fur. 
3. Cuscus (S.) CHRYSORRHOS. 
Cuscus maculata, var. 1, 2, Gray, P. Z. 8. 1858, p. 102. 
Phalangista maculata, Temm. Mam. t. 2. f. 1-5 (adult), 6 (young 
skull). 
The grinders * large, three front of from 10 to 103 lines in length. 
Fur dark grey-brown ; sides and middle of the back blacker or 
black ; face reddish ; rump and tail yellowish ; belly white. 
Var. albina? 
White; feet and large spots on back red-brown. 
Hab. Ceram ; south coast of New Guinea ; “ Moluccas” (Temm.). 
1. An adult female of a large size from the Leyden Museum as C. 
chrysorrhos, Temm. 1859. 
2, 3. Au adult and a three-fourths grown female, with the sides 
very deep black. From Ceram; Mr. Wallace, 1859. 
4. A young female specimen from the south coast of New Guinea ; 
J. B. Jukes, 1846. 
The skull of this animal shows that it belongs to the large-toothed 
species. 
Var.? albina. White, reddish varied. 
C. maculata, nos. 3-5, Gray, P. Z. 8. 1858, p. 102. 
5. White, with a long irregular patch on the back, and the four 
feet red. A female from Dufour Island, south-east coast of New 
Guinea; John Macgillivray, 1851 ; and its skull, which agrees with 
Temminck’s figure of the skull of C. maculatus. 
6. ? An adult male, with numerous confluent reddish spots. New 
Guinea; John Macgillivray, 1855. 
7. A half-grown male, with numerous small, reddish and dark- 
brown spots, often confluent. Darnley Island, south coast of New 
Guinea ; John Macgillivray, 1855. 
I have not been able to examine the skull and teeth of these spe- 
cimens ; so they may belong to the next. 
4, Cuscus (S.) MACULATUS. 
Cuscus maculatus, Lesson, Voy. Coq. t. 5. 
Cuscus maculatus, var., nos. 3-7, Gray, P. Z.S. 1858, p- 102. 
* I give the measurement of the three first of the true grinders only, because 
in the young skull the hindermost grinders are not developed. I may state 
that the ditference in the size of the grinders does not depend on the sex of the 
species, as there are both males and females with teeth of each size.
