hinder than its anterior margin which projects most outwards. The 
carotid artery passes through a distinct canal between the bulla and 
basisphenoid, the hinder end of which appears as a conspicuous fora- 
men situated a little in front of the middle of the inner border of 
the auditory bulla. 
The orbit is never enclosed by bone; nor is the mastoid at all 
prominent. The lower margin of the hinder part of the mandible 
is very concave. The angle of the mandible is long, slender, and 
backwardly projecting; its coronoid process is not very high or 
backwardly projecting compared with that of Felis. There isa 5-5

and an ;;5- ‘There is alsoa ——and an —, 7; is of large size. 
P+ has a well-developed internal tubercle. The tongue is devoid of 
horny papillee or of any patch of conspicuously enlarged papillz on 
the anterior part of its dorsum. There is a small conical cecum. 
There is a pair of anal glands. There is also a pair of medianly- 
adjoining scent-glands placed between the penis and testes, or in 
the analogous position in the female. Their secretion escapes by a 
number of minute orifices into a large sac, the external aperture of 
which appears as an antero-posteriorly extended slit simulating a 
large vaginal aperture. 
The genus Viverra differs from all the Felide in that 
(1) The ungual phalanges are less arched, and the bony lamina 
for sheltering the base of the claw is relatively less deep. 
(2) The claws are less arched and less perfectly retractile. 
(3) The auditory bulla, being ossified, shows external signs of its 
complete internal division into two chambers. 
(4) There is a conspicuous carotid foramen on the inner side of 
the bulla, which is most prominent posteriorly. 
(5) The palatine foramina are situated on the anterior half of the 
palate. 
(6) There is a 5-5 and also an 55. 
(7) ™* is largely developed. 
(8) sj has a distinct talon. 
(9) The ears are not very long, erect, pointed, or tufted. 
(10) There are no horny, sharp-pointed, conical papille on the 
dorsum of the tongue. 
(11) The hippocampal gyrus is completely separated off from the 
lateral gyrus by the continuation of the calloso-marginal 
sulcus forwards to the crucial sulcus. 
(12) The coronoid process of the mandible is less lofty relatively and 
less backwardly produced. ‘ 
(13) The proportional length of the limbs to the body is shorter 
than even in Felis eyra. 
(14) The muzzle is longer in proportion to the cranium. 
The genus Viverra also differs from the Felide in that 
(15) There is a distinct hallux with a claw. 
(16) There is an alisphenoid canal.
