T^/'e. Male (skinned from spirit). Collected by ^Ir. A. A. 

 Kutsenko. One sj)eeimcn. 



This species is readily distintruished by its much fi;reater 

 size from its only near ally, the European and Persian EUomys 

 {l>ryomys) nitidula. It is chiefly interesting by the immense 

 reduction which its discovery in Central Asia effects in the 

 great geographical gap between the Japanese dormouse 

 [GliruhiH jnjionlcus) and all the other members of the sub- 

 family (iliriniu. 



The type specimen had had its tail broken during life, and 

 liad then produced a bony continuation to the vertebral 

 column, supporting the thickened tail-end, as described 

 elsewhere *. 



Lepus VassaU, sp. n. 



A small species allied to L. haitmnus, but much paler in 

 colour. 



8ize about as in L. hai'nanus, conspicuously smaller than 

 in L. peguennis and sianiensis. Fur rather short, the longer 

 liairs of the back about 25 mm. in length. General colour 

 above heavily lined drab, the light rings on the hairs near 

 " creani-bufl/^ the resulting colour very different to the 

 cinnamon of L. hainanus. The wool-hair whitish slaty at 

 base, darkening to black terminally, without an intermediate 

 buffy or fulvous ring. Sides inconspicuously washed with 

 pale cinnamon; chin and belly white; chest-band coarsely 

 giizzled buffy drab. Top of muzzle cinnamon, sides white, 

 a whitioh-grey line running through the eye to the base of 

 the ear ; crown like back. Ears of medium length ; proectote 

 grizzled drabby, the long fringe-hairs nearly white ; metectote 

 mostly naked, inconspicuously black terminally; raetentote 

 thinly haired, dull whitish, with a darker band along the 

 middle of the outer edge, its extreme edge white. Nuchal 

 })ateh dull rufous. Fore limbs cinnamon, hind limbs similar 

 but paler ; palmar and plantar hairs dirty whitish. Tail 

 black above, white on sides and below.
