Dr. J. E. Gray on the Genus Cuscus. 249 
We have in the British Museum a young specimen of a Cuscus 
from Macassar, which is very like C. celebensis, but it has no visible 
dorsal streak: it is not in a very good condition. It may be a va- 
riety of this species, or the young of one of the other, or perhaps 
an undeveloped state of a new one. 
Skull of Cuseus celebensis (side view). 
Sect. 1V. The nose of the skull rather produced, rounded. The an- 
terior conical false grinders two on each side above, the anterior rather 
larger, the hinder very small, cylindrical ; both near the other grinder, 
and widely separated from the canines. The forehead with a deep 
concavity between the orbits. Ears naked within, extended beyond 
the fur of the head. Fur on body and tail uniformly coloured, with 
a dorsal streak. Cuscus.
