SCLATER 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, 3-j-| inches in length from base to tip, and about 1| 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-Ar inch in length ; but there are numerous 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 appearance of the fur. Length from nose to vent 14 inches ; tail 2k inches. Hab. 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. pallipes I do not say, as the specimen is in a very wretched state of preservation. 3. A Revised List of the Neotropical Larida. By P. L.
