No. 310. ARCTOMYS BOBAC.
The Bobac, or Poland Marmot
(Thibet Marmot of Jerdon, No. 168).

Native Names.—Brin, Kashmiri; Kadia-piu, Thibetan; Chibi, Bhotia; Lho, or Potsammiong, Lepcha.

Habitat.—The Himalayan range from Kashmir to Sikim, in Thibet, Ladakh, Yarkand, also throughout Central Asia and Eastern Europe from the south of Poland and Gallicia over the whole of Southern Russia and Siberia, to the Amoor and Kamtchatka.

Description.—Above sub-rufescent cat-grey, washed with blackish brown on the back and sides and front of face, rufescent yellow beneath; the hind limbs more rufous; fur close, adpressed, rather harsh; tail with a black tip.

The hairs are tinged with three bands of dusky rufescent yellow and blackish-brown, the latter being most intense on the face, forehead, head and back (see ‘P. Z. S.’ 1871, p. 560). In the plate given in the report by Mr. Blanford on the mammalia collected during the second Yarkand Mission the back is somewhat barred with dark brown, as is also the tail. The sexes are alike, and of nearly equal size.

Size.—Head and body, about 24 inches; tail, 5 to 6 inches. This animal is seldom found at a lower elevation than 12,000 feet, and from that to 16,000 feet according to Jerdon, but Dr. Stoliczka noticed it in Ladakh at a height of 17,800 feet.

“It burrows in the ground, living in small societies, and feeding on roots and vegetables. It lifts its food to its mouth with its fore-feet. It is easily tamed. One was brought alive to Calcutta some years ago, and did not appear, says Mr. Blyth, to be distressed by the heat of that place. It was quite tame and fearless, and used to make a loud chattering cachinnation. It was fond of collecting grass, &c., and carrying it to its den. Travellers and sportsmen often meet with this marmot, and speak of its sitting up in groups, and suddenly disappearing into its burrows. The cured skins form an important item of commerce, and are brought to Nepal, and in great numbers to China” (Jerdon). Mr. Blanford, in alluding to the conditions under which marmots are liable to produce permanent varieties, says: “each colony or group being isolated, and frequently at a distance of many miles from the next colony, the two in all probability rarely, if ever, breed with each other.” Therefore several which are recorded as distinct species may in time be proved to be merely varieties of one. Mr. Blanford keeps to the specific name Himalayanus of Hodgson in his report.
