head of the youngest specimen is not so concave as that of the two 
older ones. 
We have an adult and half-grown female from Celebes, obtained 
for the Leyden Museum in 1843; and a nearly adult specimen 
without any distinct indication of its sex—probably a female—with 
‘the pouch sewed up, from the Zoological Society, 1855. 
If this should be the case, we have only female specimens of this 
genus; but I believe they have a male at Leyden. 
2. Cuscus (E.) Brevicaupatus, Gray, P. Z. S. 1858, p. 102. 
Pale brown ; the tail and rump of the same colour as the back. 
Hab. Cape York (Mr. Macgillivray). 
The skull, which is that of a very young animal, is more like that 
of C. ursinus than that of any other species in our Collection. 
The canines are close to the cutting-teeth, and with a very small 
space between it and the first grinder. The skull is rather convex, 
and swollen in front over the orbits. 
We have only the young specimen and its skull, on which Mr. 
Gould established the species. It seems very distinct from C. ursinus. 
Sect. Il. The nose of the skull rather produced, rounded. The ante- 
rior conical false grinders one on each side above, moderate-sized, near 
the middle of the broad diastema. The grinders in a slightly arched 
series. ‘The forehead very convex, rounded over the middle of 
the orbit, and flat behind. The ears hairy outside, hidden in the fur. 
The fur more or less variegated. ‘Tail pale or yellowish. Dorsal 
streak none. SpiLoOcuscus. 
The skulls which we have of the animals of this section show 
that there are probably two distinct species. One species has grinders 
of a rather larger size than those of C. ursinus, but differmg from 
them in being in_only a slightly curved line, the three first grinders 
forming a series of from 10 to 103 lines, or twelfths of an inch. 
In this respect the skull agrees with those figured by Temminck 
(Mon. Mam. t. 3. f.1-6) as of Phalangista maculata. But one skin 
agrees with the description of the skin of P. chrysorrhos of that 
author, and its teeth with the figure of the teeth of P. maculata. 
Yet it is to be recollected that this author had only a very small 
number of specimens to examine, and he does not, mention in his 
description of either species the difference in the size of the grinders, 
though he shows the difference in his figures. 
The second species has smaller grinders, placed in the same man- 
ner as the former,—the three front grinders forming a series of from 
81 to 9 lines in length, as they are figured by Temminck (Monog. 
t. 1. f. 4-6) as Phalangista chrysorrhos. 
We have two skulls with their skins belonging to this kind; and 
both have the spotted skins which Temminck calls Phalangista ma- 
culata. Under these circumstances it is difficult to adopt Tem- 
minck’s name. Are we to take those of the skin or those of the 
skulls? Perhaps what he describes as C. chrysorrhos may be the 
proper and wild state of each species, and the spotted varieties de-
