Collector's note :-" Ukamba, 5000 ft., Athi Plains, July 15th, 1898. Weight about 3| lbs. This Hare frequents the bare open plains of the Upper Athi Biver, where there is not a tree for miles and miles.*'-li. C. Measurement of the ear in the dry specimen 120 millim. The upper incisors are moderate in width, with the front surfaces level; the grooves are placed near the inner edge, they are shallow, diverging inwardly, and entirely filled with cement. The back of the nasal bones is gradually bowed from the outward edge, forming a wide V. This Hare is closely allied to L. tigrensis Blanf., from Abyssinia, and probably that species does not diifer much except in being rather larger.

The rather narrow upper incisors are quite flat, the inner and outer sides of the grooves being on the same level; whereas in L. whytei these teeth are very broad, the part on the inner side of the groove projects considerably, and on the outer side of the |
