new Hare from the Trayisvaal. 405 



ring. Tliese hairs give the middle part of the back a parti- 

 cularly dark grey appearance. Wool-hairs buff, without the 

 slaty-grey bases characteristic of P. Ruddi. 



Under surface buff, passing into grey on the flanks, so that 

 there is no sharp line between back and belly. This grada- 

 tion is due to the amount of black in the long coarse hairs 

 becoming less towards the ventral surface, until, in the mid- 

 ventral region, these hairs are entirely buff-coloured. 



Head bluish grey, with a slight rufous tinge on the fore- 

 head. Nape-patch small and inconspicuous, rather more 

 rufous tlian back. Throat and chest as back. Ears grey, as 

 in P. Ruddi, but without the black edge. Limbs buffy 

 rufous, not any lighter towards digits. Soles black. 



Tail very large and bushy, about 140 mm. long, including 

 the hairs ; dark reddish brown, pencilled with black, at base; 

 distal third of tail black. 



Skull as in P. Ruddi, but slightly larger and rather 

 narrower in the nasal region. The palatal foramina are not 

 quite so much narrowed posteriorly, their inwardly directed 

 edges, so conspicuous in P. Ruddi, being reduced to mere 

 narrowed ridges of bone, so that the walls of the nasal 

 chamber are exposed, as in P. crassicaudatus. The notch in 

 the incisors is more distinct than in Thomas's figure of the 

 skull of P. Ruddi (P. Z. S. 1905, i. pi. xvi. fig. 4). The 

 upper molars have the uncrenulated anterior enamel-wall of 

 the posterior lamina extending considerably less than halfway 

 across the tooth, thus presenting conditions intermediate 

 between P. Ruddi and P. crassicaudatus. The anterior lower 

 premolars also show an intermediate condition, their anterior 

 walls having a single notch on the left side and a double one 

 on the right.
