and feet flesh-coloured.

Jerdon says the young are pure black and white; the teeth are bright

ARCTOMYDINAE--THE MARMOTS.

Stout-bodied, short-tailed animals, with a rudimentary thumb with
a flat nail. They are gregarious and terrestrial, living in burrows,
where they store provisions against inclement seasons. Some of the
genera have cheek pouches, but the true marmots, such as our Indian
species, have not. They differ somewhat in dentition from the
squirrels in having the first upper molar somewhat larger, and the
other molars also differ in having transverse tubercles on the crown.
The first upper tooth is smaller than the rest; the ears are short
and round, as is also the tail; the hind-feet have five toes, the
fore-feet a tubercle in the place of the thumb.

_GENUS ARCTOMYS_.

Stout body, short tail, large head and eyes, no cheek pouches, mammae
ten to twelve.
