Hab. Nepal. 
The skull elongate; nose rather short, compressed ; brain-case 
narrow in front, swollen over the ears, and contracted and produced 
behind. Orbits not defined behind, confluent with the temporal 
cavity ; zygomatic arch slender. Palate contracted behind. Teeth 
38; upper false grinders compressed; flesh-tooth narrow, much 
longer than wide in front ; the outer edge three-lobed, inner tubercle 
on the front edge; tubercular grinders transversely trigonal, much 
wider than long, the outer edge sloped, and the hinder lobes in the 
middle of the hinder edge. There is no hinder tubercular ; but the 
one present is quite like the front tubercular in the typical Viverride. 
The skulls of the two species are very similar; but the skull is 
rather larger, the palate narrower in front and behind, and the bulle 
of the ears are narrower and less ventricose in P. gracilis than in P. 
pardicolor. 
The following are the measurements in inches and twelfths in P. 
gracilis :—length of skull 1" 7!"; width at brain-case 11! ; width of 
zygomatic arch 1" 33!"; length of nose 9!'. P. pardicolor :—length 
of skull 2" 6'"; width of brain-case 103!" ; width of zygomatic arch 
1" 23"; length of nose 83!".

Skull and teeth very like Prionodon; but the brain-case is ovate 
and more ventricose. The orbits not defined behind, and confluent 
with the temporal cavity; zygomatic arch stronger. The nose is 
compressed. The palate is very narrow behind. Teeth 38; the
