‘there is considerable variation in colour among them.

6. Kaka, 2nd March. 
Type. B.M. no. 1, 8. 8. 40. 
Closely allied to L. ethiopicus, Ehr., but greyer and less 
sandy throughout. 
Size as in the allied species. General colour above soft 
fawn-grey, finely lined with black. Dorsal hairs at base pale 
silvery slate-grey, darkening above to black on the middle 
third, then subterminally ringed with buffy white, the tips 
black. In LZ. wthiopicus the base is whiter and less slaty 
and takes a sandy tone below the black ring, and the sub- 
terminal light ring is a strange sandy buffy. Flanks markedly 
greyer and less sandy than in L. ethiopicus. Under surface 
white, the usual collar pale isabelline. Face like back, 
though less heavily grizzled; ante- and postorbital light 
markings as usual. <A white frontal spot present. Anterior 
part of back of ears greyish isabelline, the long hairs at its 
edge sandy buffy for three fourths the length; tips black 
behind for the terminal half-inch, the marginal hairs also 
black, though partly hidden by the sandy hairs of the inner 
side of the edge. In L. ethiopicus there is scarcely any 
black behind the tip of the ear. In length the ears appear 
to be decidedly shorter than in L. ethiopicus. Nape-patch 
comparatively small, dull sandy, markedly smaller and less 
vividly sandy than in the allied species. Tail black above, 
edged with buffy, white on sides and below. Front of fore 
limbs and hind limbs to ankles pale greyish ; upper surface 
of hind feet whitish. 
Skull very much as in L. ethiopicus, the occipital shelf 
rather narrower. Enamel of upper incisors making a deep 
but simple V-shaped projection into the tooth. 
Dimensions of the type (measured in the flesh) :— 
Head and body 410 millim.; tail 60; hind foot 96; 
ear 100. 
Skull: greatest length 80; basilar length 62; greatest 
breadth 39; nasals 34 (diagonally) x 17-5;  interorbital 
breadth 17:2; diastema 22. 
This hare is no doubt the southern representative of 
L. ethiopicus, Khr., of which some excellent examples from
