representative of L. Intra in Assam is L. /. monticola. Lutra L 
barang represents this species in Siam and Annam; and L. /. 
chinensis in Laos, Tonkin, southern China, Hainan, and For- 
mosa. Much farther north L. lutra is recorded in Manchuria 
and Siberia and as far north as the Kolyma River, and in Sak- 
halin. A weakly separable species, L. tarayensis, occurring in 
upper Burma and possibly lower Yunnan, has the back of the

nose pad straight across instead of with the usual three nearly 
equal, pointed projections of glandular skin penetrating the 
furred area. Lutra lutra in the Burma-Indo-Chinese Peninsula 
overlaps the range of L. sumatrana but is somewhat smaller. 
The length of the head and body varies from 22 to 28 inches, 
and of the tail from 14 to 18 inches, the foot from 4 to 4% 
inches. The color is brown above, whitish brown beneath, due to 
the white tips of the brown hairs of the underparts. The white 
throat and cheeks contrast sharply with the brown nape and 
crown. 
The Hairy-nosed Otter, Lutra sumatrana, as its name im- 
plies, has the greater part of the nose pad covered with fine hairs. 
Only the lower edge and the margins of the nostrils are naked. 
The color is chocolate-brown, scarcely paler below ; the cheeks.
