Descriptions of East Asiatic Mammals 203 
Red-tailed Hare, L. ruficaudatus, of northern India and Assam ; 
the Burmese Hare, L. peguensis; and the Assam Hare, L. 
sadiya. 
The Harsh-furred Hare, Caprolagus hispidus, of the east 
Himalayan foothills and Assam (whence came the specimen on 
which the genus was based), is the only known species of the 
genus Caprolagus. 1 The ears are unusually short, only 2 inches 
long, the feet are 3% inches long, and the tail, including the 
hairs, measures only l 1 /^ inches. The skuH, compared with Lepus 
timidus and L. europceus, is more massively built, even though 
the animal is actually much smaller; and the teeth, both the 
incisors and the molar i form teeth, are extraordinarily thick and 
broad. The width of each incisor is more than % inch, compared 
with % inch in Lepus hainanus and L. sinensis. The groove on 
the face of each upper incisor has in section a simple V-shape 
without the complexities to be seen in Lepus hainanus or the 
Indian Hare group ; the groove is filled with cement. 
The color of the Harsh- furred Hare is rather dark, a mixture 
of dull brown, blackish, and numerous scattered whitish bristly 
hairs; the underparts are buffy gray, the feet and hands dull 
brown, and the ears lack the light-colored fringes commonly 
seen in Lepus. The tail is brown, without white beneath. The 
length of head and body is only 15 to 20 inches. The number of 
nipples has been reported to vary from 6 to 10. The animals 
are reputed to make burrows but the claws seem too long and 
slender for digging. 
The True Hares, genus Lepus, can be distinguished from 
Caprolagus by their proportionately narrower incisor teeth and 
larger ears. For practical treatment the oriental forms are divisi- 
ble into four groups : the timidus group, the europceus group, the 
hainanus group, and the ruficaudatus group. The last two groups 
have the grooves in the upper incisor teeth moderately complex 
and very complex respectively, as stated previously. The other 
1 Contrary to the view expressed by Allen, the Hares of south China are 
not referable to Caprolagus; their teeth and skulls are like those of Lepus.
