 hairy, the base of the nasal septum alone naked. Quality of fur 

 much as in L. consjoidllatus. Underfur long and soft, everywhere 

 on the body dark slaty grey at base, broadly tipped with pale brown, 

 and that on some parts with a second darker subterminal band. 

 General colour exceedingly like that of a Common Hare, even more 

 so than in L. conspicillatus. Head coloured on the same essential 

 pattern as in L. conspicillatus, but far more obscurely, and the 

 rufous colour round the eye more prolonged forwards on the sides 

 of the muzzle. Ears comparatively long, their length going from 

 2| to 3 times in that of the hind feet, their backs and insides 

 whitish. Back with the subterminal pale band on the longer hairs 

 white with a tinge of yellow, the yellow disappearing on the rump. 

 Sides with a very faint and inconspicuous trace of the two lateral 

 bands present in L. conspicillatus. Chin, chest, and belly dirty 

 yellowish grey. Arms with a well-marked black patch on the 

 outside of the proximal half of the forearm, caused by the entire 

 absence of longer piles, and the consequent prominence of the 

 iinderf ur, which is here nearly black. Legs Hke body ; hands and 

 feet finely grizzled greyish white. Tail thinly haired, grizzled 

 brownish grey above, nearly white on the sides and below. 



Skull light and slender, with a long narrow muzzle ; facial index 

 230-235. Nasals long and narrow, their greatest breadth going 

 about 2| times in their length, slightly • expanded behind; their 

 posterior border evenly curved backwards, slightly recurved forwards 

 in the centre. Interorbital space fiat, its edges parallel, sharp, but 

 little overhanging. Palatal foramina short, barely the length of m.' 

 Posterior palate with considerable vacuities. Bulte much swollen, 

 globular, smooth and transparent., 



Teeth. Incisors (PL IX. fig. 13) small and delicate ; i.^ much 

 slanted forwards, slightly exceeding i." in horizontal length, its 

 notch about the centre of its outer edge. Canines very small, 

 scarcely projecting above the gum. P.* oblong, parallel-sided, about 

 the length of m.*, its internal ledge running its whole length.
