Size and general colour above nearly as in L. capensis, but the 

 back is more uniformly grizzled and less mottled. Fur decidedly 

 harsher than in that species. Forehead with a white spot. Ears 

 comparatively short; their external band brown all along, with a 

 whitish margin ; their extreme tips only black. Xape bright 

 rufous. Sides slightly more rufous than back, but not nearly so 

 much as in L. capensis. Chin white. Chest rufous fawn, as 

 are also the upper surfaces of the hind feet. External surface of 

 fore limb, and line down hind leg, richer rufous. Tail rather 

 short, black, more or less mixed with rufous fawn above, white 

 below. 



Skull with a short muzzle, very broad proximally, narrow inter- 

 orbital region, and narrow posterior narial fossa. Incisors broad, 

 their groove close to their inner edge. 



Dimensions of the type, an adult skin, female : — 



Head and body 468 mm.; tail without hairs (c.) 47; ear, from 

 notch, 88 ; hind foot, without claws, 95. 



Skull : basal length 68 ; basilar length 65-5 ; greatest breadth 

 42-5 ; nasals, greatest length 37, greatest breadth 18 ; inter- 

 orbital breadth 16-2 ; intertemporal breadth 12-7 ; diastema 21-5 ; 

 anterior palatine foramina, length 20*5, combined breadth at 

 surface 9-2 ; width (antero-posterior) of palatal bridge 8-6 ; least 

 breadth of posterior narial fossa 5. 



This Hare, which 1 have much pleasure in naming after aIi\ 

 Alexander AVhyte, the able seconder of Mr. Johnston's efforts to 

 investigate the fauna of Nyasa, is readily distinguishable from 

 L. cupensis by its harsher fur, rufous nape, shorter ears, feet, and 

 tail, and somewhat different coloration. It is by no means 

 improbable that the specimens from Angola which have been 

 referred to " L. ochropus, Wagn.," really belong to L. whytei, but 

 this point can only be determined later. The typical L. ochropus 

 was described from the Cape itself, and, in agreement with Water- 

 house, I can see no possible reason why it should not be looked 

 upon as strictly synonymous with L. ccq)cnsis.
