248 Zoological Society :-— 
Phalangista chrysorrhos, Temm. Mon. t. 1. f. 4, 5, 6 (skull, not 
skin). 
Grinders moderate, three front forming a series of from 81 to 9 
lines in length. Skull very convex on the front of the orbit, flat or 
slightly concave behind the convexity, the temporal ridges close toge- 
ther, united (in the adult skull) and forming a sharp ridge. 
White, spotted with fulvous grey-brown or black ; forehead 
reddish. 
Hab. New Guinea. Waygeroo and Aru Islands. 
There are both sexes in the Museum Collection. 
1. Adult male. Spots on the head and shoulders, confluent on the 
back and sides, small, scattered ; tail white. Waygeroo. Purchased 
of M. Verreaux, 1856, as Cuseus maculatus. 
2. Adult male. White, with numerous, scattered, small spots ; tail 
white, slightly varied with pale reddish. Aru Island; Mr, Wal- 
lace, 1857. This belongs to the smaller-toothed kind. 
3. Adult male and female. Very similar; yellowish white spots, nu- 
merous, smooth, intense black; head reddish-brown; tail white, 
marbled with pale reddish. Waygeroo; Mr. Wallace, 1860. 
Mr. Wallace observes that these animals are diurnal: the female 
he marks as having a pale hazel iris. The skull of the male shows 
that it also belongs to the smaller-toothed kind. 
The three skulls in the Museum agree with the above description, 
but vary among themselves ; one of the skulls from Aru (1195 6) is 
much narrower in all its parts, and is less swollen and narrower be- 
tween the orbits, than the others from the same locality, and is pro- 
bably the skull of a female, as 11954 is from the male specimen 
sent from Aru by Mr. Wallace. 
The skull of the male specimen sent by Mr. Wallace from Way- 
geroo is similar to the male from Aru (1195 a), but is rather more 
swollen, especially between the front of the orbits. 
Sect. III. The nose of the skull rather produced, rounded. The 
anterior conical false grinders one on each side above, moderate-sized, 
near the middle of the broad diastema. The forehead deeply concave, 
with a raised edge on each side between the orbits. Ears naked 
within, extended beyond the fur of the head. Fur of body and tail 
uniformly coloured, with a dorsal streak. Srrieocuscus. 
5. Cuscus (S.) ceLeBensis, Gray, P. Z. 8. 1858, p. 105, t. 62. 
Hab. St. Cristoval, Solomon’s Group of Islands. 
We have both sexes in the British Museum Collection, and the 
skulls of two others nearly adult, collected by Mr. Rayner and Mr. 
J. Macgillivray during the voyage of the ‘ Herald.’ There is very 
little difference between the two skulls, though they are from a male 
and female animal. 
In the description of the species in the paper above referred to, 
the animal is erroneously said, by a slip of the pen, to have no 
dorsal streak.
