small cones ; the inner lobe occupies more than half the inner part 
_ of the tooth, with two unequal cones, the front one being nearly as 
large as the middle one on the outer side. The front tubercular very 
large, oblong, with nearly equal sides and large tubercles ; the hinder 
upper tubercular much smaller, circular.

it was marked in the catalogue, “Skull of a Genet undetermined.”

Nose flat beneath, with a central longitudinal groove. The skull 
broad, short. Brain-case broad between the orbits, only moderately 
constricted in front ; forehead triangular behind, extending beyond 
the back edge of the orbits. The orbit very incomplete, with a very 
short acute prominence above behind, and none on the zygomatic 
arch below; hinder part of palate broad, with a very slight notch 
on each side of its front edge; the front of the palate broad, about 
as wide as three-fourths of its length. Teeth small or moderate ; 
flesh-tooth triangular, the front edge about as broad as long on the 
outer edge ; the front tubercular oblong, inner edge shorter, rounded. 
The skull of this genus is easily known by the distinct forehead, 
the edge of the temporal muscles even in the oldest specimen leaving 
a plane triangular space over the back of the eyes. 
This genus was first established on an animal that had not com- 
pletely shed its teeth ; but the examination of the adult skull has 
justified the separation. 
The following are the most prominent peculiarities of the skulls 
of the three species :— 
1. P. larvata is the smallest, has the broadest nose, as shown by 
the shape of the roof of the mouth or palate, and the smallest teeth. 
2. P. grayi is next in size, has alonger and narrower nose, larger 
teeth, and a larger and more convex forehead. 
3. P.leucomystaz is the largest, with a short, very broad nose, and 
wide palate, and very large massive teeth. 
The hinder opening of the palate in P. Jarvata and P. leucomystax 
is angularly cut out behind; in P. grayi, arched out. The brain-case 
is widest and least contracted in front in P. larvata and P. leuco- 
mystax, and most so in P. grayi. This contraction becomes more 
decided as the specimens increase in age. 
* Skull short ; brain-case scarcely constricted in front; the nose 
very broad. Paguma.
