This hare is much smaller than L. hypsibius, and very differently coloured ; the fur is much 

 shorter and less woolly, and the tail has a hroad black band above. The skull differs in several 

 points. The palatine opening is much broader behind, the molars comparatively wider apart, 

 muzzle shorter, the postorbital processes rise much less above the plane of the frontals, the 

 lower edge of the zygomatic arch is nearly straight and not angulately convex, &c. 



Prom the shortness of the fur I should have anticipated that this hare would be an 

 inhabitant of a less severe climate than L. pallipes and the species hereafter described. 



Recently specimens of a hare procured by Major Biddulph in Yassin near Gilgit, and 

 closely approaching L. tibetanus in external characters, have proved, on examination of the 

 skull, to belong to a different species, and have been described by myself as L. biddulphi. 1

 a slight dusky tip ; face and anterior portion of the ears the same colour as the back ; lower 

 parts, as usual, white"; fur very soft and long, fine and woolly towards the base, and with 

 numerous bairs rather longer than the rest, scattered throughout the body ; these hairs have
