206 Mammals of Eastern Asia 
The Woolly Himalayan Hares and Gray-tailed Hares, 
Lepus oiostalus and allied races, also relatives of the L. euro- 
pceus group, are remarkable for the length of their ears, which, 
as in europceus, may reach 5 inches. These are beautiful big 
Hares with the color tone of the fur a mixture of brown and 
much silvery gray. The tail, which is 4% inches long, has the 
upper surface virtually white. The foot is long as in europceus. 
This species occurs in Tibet, north of Nepal and Sikkim, at 
elevations as high as 16,000 feet and just reaches the extreme 
southwest of China. Two Chinese races found at somewhat 
lower levels are L. o. grahami from Szechwan, 10,000 feet, and 
L. o. comus from Yunnan, southern Szechwan, and extreme 
northern Burma at 6000 feet. The tail of grahami is dark gray 
above, gray or white beneath; of comus brown above, elsewhere 
gray. 
The Hainan Hare group includes Lepus hainanus from 
Hainan Island, Lepus vassali from sea level in Annam and 
Cochin-China, and Lepus siamensis from Siam and Laos. All 
have the grooves of the teeth moderately complex but less than 
in the Indian and Burmese species that follow. All are rather 
small, with small ears and feet and moderately shortened tails. 
The color of hainanus is tawny brown mixed with blackish, the 
ear fringes white, the top of the tail blackish, its underparts 
white, the feet pale brown with white marks, a whitish mark in 
front of each eye. The underparts of L. hainanus are snow- 
white from the chest to the vent and under the chin, tawny on 
the neck and throat. Length of head and body about 18 inches, 
tail 2y 2 inches, foot 3 to Z 1 /^ inches, ear 3 to 3% inches. Lepus 
vassali and L. siamensis are very similar; perhaps they are races 
of hainanus. 
Of the Indian Hares — those with complexly grooved incisor 
teeth — three forms exist in southeast Asia : the Red-tailed Hare, 
the Burmese Hare, and the Assam Hare.
