Helictis\—Dentition : i 3, ¢ 3, p 4, m 4; total 38. Upper 
carnassial with a large bicuspid inner tubercle ; upper molar 
smaller, wider transversely than in the antero-posterior direction. 
Lower carnassial with talon about one-third the length of the tooth. 
Skull elongated, 
rather narrow 
and depressed. 
Facial portion 
especially nar- 
row. Infra- 
orbital foramen

Fic. 265.—Helictis personata. (From Blanford, Mammalia of British gnout. Ears 
India, p. 175.) small. Body 
elongated. Limbs short. Tail short or moderate, bushy. Several 
species are described (ZH. orientalis, personata [Fig. 265], moschata, 
subawrantiaca), all from Eastern Asia; they are all small animals 
compared with the other members of the subfamily, climbing trees 
with agility and living much on fruit and berries as well as on 
small mammals and birds. The two first named species occur in 
British India, H. orientalis also ranging into Java; the Chinese 
fZ, subawrantiaca is brilliantly coloured in the region of the throat.? 
Fic, 266.—Left lateral and superior aspect of the brain of Helictis sabaurantiaca. (From 
Garrod, Proc. Zool. Soc. 1879, p. 807.) 
The brain of Helictis, represented in the accompanying figure, 
shows the general type of cerebral structure characteristic of the 
Mustelide. The brain of this genus differs, however, from that 
of every other Carnivore in that the hippocampal gyrus rises to 
the surface on either side of the great longitudinal fissure, in
