564 MESSRS. SCLATBR AND SALVIN [June 20, 



General colour of back anterior to sacral region, neck, and head 

 pale fulvous buff, mottled with black and yellowish white, darker 

 on the face and on the internal half of the posterior surface of the 

 ear, the latter area being concolorous with the forehead ; a rufous 

 tint on the back of the neck ; hind quarter pale ashy grey ; tail 

 white, with an ashy-grey line above ; limbs and under surface of 

 neck, shoulder, groin, front of fore legs, under surface of feet, and 

 upper surface of hind feet rather rufous buff ; chin, throat, chest, 

 belly, external half of posterior surface of ear, and inside of legs 

 pure white. The ear is longer than the head, 3j-f inches in length 

 from base to tip, and about If inch in breadth ; its internal surface 

 is densely covered with yellowish hairs, and the lower half of its 

 inner margin with long white, rufous-washed hairs, and is tipped 

 with black at the apex. Whiskers black and white, or black with 

 long white tips. Incisors white. Nails dusky at the base, with 

 horny-coloured tips. Fur very fine and woolly, of moderate length 

 and silky texture ; it is about 1-f^ inch in length ; but there are nu- 

 merous long hairs scattered through it measuring 2 inches long. 

 The basal ^ inch of the fur is slaty ; and many of the hairs have a 

 black tip to the broad buff band that succeeds the darker band. 

 Many of the long hairs on the buff parts of the upper surface have 

 long black tips, while others have broad yellowish-white subapical 

 bands, which, along with the black tips, produce the mottled appear- 

 ance of the fur. Length from nose to vent 1 4 inches ; tail 2i inches. 



Sab. Tibet. Four specimens. 



A. specimen of a Hare in this Museum, referred to L. pallipes, is 

 essentially ochreous, as described by Waterhouse, and pencilled with 

 black ; and the base of the fur is white, instead of slaty as in L. 

 tibetanus. The ears are coloured as in this species ; but I cannot 

 give their length, as the skin has not the skull in it and the head 

 is much distorted. It appears to be a somewhat larger Hare 

 than L. tibetanus, and is distinguishable by its rather rich ochreous 

 coloration and black pencillated fur, which is white at its base 

 instead of being slaty. "Whether it is correctly referred to L. pal- 

 lipes I do not say, as the specimen is in a very wretched state of 

 preservation .
