being intermediate between that species and H. galeata. ‘This can be illustrated by 
the following figures based on my own measurements. In H. africce-australis the 
anterior breadth of both nasals are from 52 to 60°/o of the posterior breadth of the 
same bones. In the Somalirace the same relation is 60 to 63 °/o but in H. galeata 
above 70 °/o. 
The nasal process of the Somali Porcupine is very broad and resembes that 
of H. galeata. It measures in my specimen fully 17 mm. The maxillary portion of 
the zygomatic arch is inflated by the air-sinuses and measures about 15 mm, across. 
The distance from lacrymale to the zygomatic suture is about 12 mm. 
The upper incisors appear to be narrower than in H. galeata so that their 
combined breadth above the cutting-edge only measures 10 mm., while the same 
measurement in the H. galeata specimens of this expedition is resp. 12 and 13 mm." 
With regard to exterior characteristics the differences between the Somali race 
and typical H. galeata are not very great. The latter appears, however, to judge 
from a comparison with four specimens to have more white in the crest, longer white 
tips to the quills of the rump, and the quills round the tail with the white domi- 
nating unlike H. g. somalensis in which the white tips to the quills of the back are 
decidedly shorter, and broad black rings to be seen also on the quills around the tail. 
The specimen of H. g. somalensis obtained at Njoro was by chance found above 
the ground. It ran out from below a thornbush where it had intended to sleep 
over the day.

This species is probably common in the neighbourhood of Nairobi, but as also 
the following species is found there it is difficult to say which of the two species is 
most numerous. I obtained specimens at a farm managed by Mr. HAMPSON some 
distance northwest of Nairobi. 
A young Hare caught at Juja farm **/: is also referred to this species. 
They were usually found in open places under isolated or small groups of bushes 
or patches of plants. Old termite hills which had fallen down and were overgrown 
with coarse plants, a common feature in the landscape, were favourite places for the 
hares. They sit rather close and run with great speed. 
Lepus crawshayi Dre WINTON.

Specimens of this Hare were obtained not far from Nairobi on a grassy plain 
near the Limuru road, and on a steppe with rich growth of grass near Rooruka river, 
‘In not yet adult specimens of H. galeata I have seen this measurement only amounting to about 
11 mm. but never so small as 10.
