y No. 99. 11.5.2, Camp, 1898," Chinese Turkestan, altitude 16,500 ft., August 8th, 1898.

Native name, " Such Kun." Type, no. 97.1.21.3.

Description. External characters similar to those of M. straeheyi Thos., but with the teeth and posterior termination of the palate very like those of M. roylei Ogilvie. Agrees with M. albicauda True in that11;. i has 8 salient angles, but has the tail far shorter.

Skull (damaged posteriorly)—zygomatic breadth 14.5 ; length of nasals 8.5 ; palatal length 14.5 (from posterior termination of palate to anterior margin of incisors).

Type, No. 99.11.5.3. Y , Nura, Chinese Turkestan, 7,500 ft., 6th October, 1818 (original number 73).

Description. In external appearance resembles D. loftusi 131anford, but the colour of the upper surface is richer and not so brown the exact tint being somewhere between Ecru drab " and Pawn colour "

Skull resembles that of D. lagopus Licht., but the teeth are more massive and their pattern less complicated.

Dimensions of the type-- head and body 125 ; tail 160 ; hind foot 59 ; ear 18. (All taken from the dried skin.)

This is a very distinct Jerboa, with no very near known ally, and a detailed description of which would be unnecessary. I have pleasure in connecting it with the name of its discoverer.
