small Mammals from Uganda. 319 
sembling A. barbarus, L., but blacker in tone and the stripes 
narrower. Central dorsal stripe black-brown ; the region on 
either side, extending over two dark and two light stripes, 
strongly washed with brown ; outside of this space the dark 
stripes are black, with a few light-coloured hairs intermixed, 
the light stripes buff-white, every second one being rather 
more conspicuous ; the stripes get rather more broken nearing 
the belly. All the underparts buff-white. The ears are well 
clothed with brown hairs, but do not show nearly so much 
rufous as those of A. barbarus; the tail, which is also well 
covered with hair, is black along the middle line, inclining to 
rufous on the sides and buff-white beneath. Feet buff-white, 
claws brown. 
Type 638. 7.7.23 in the British Museum; collected by 
Capt. Speke in Unyamuezi. 
Measurements taken from skin:—Head and body 120 
millim. ; tail (end broken) ; hind foot 23°5; ear 13. 
Skull: greatest length 29; breadth across zygomata 14, 
across brain-case 12°5; nasals 11 x 3:5; interparietal 3x8; 
basal length 25; henselion to back of palate 12:7; palatal 
foramina 5°1x2; upper molar series 5:3; outside ™-! 6:5, 
inside :2"3. 
Incisors broad, orange above, rather paler below. Man- 
dible (bone only), length 15°5, height at coronoid 9. 
Compared with a mouse from Wadelai, which I take to be 
A. zebra, Heugl., the present species is larger, the stripes 
narrower and not so clearly defined; the size is intermediate 
between the Wadelai animal and A. barbarus, and therefore 
about equal to A. pulchella. The skull, compared with that 
of the last-named species, differs as follows :—narrower more 
pointed nasals, narrower interorbitally, profile more arched, 
smaller palatal foramina, molars rather more drawn out, 
incisors broader, the mandible has a deeper notch behind 
between the angle and the longer and more horizontal 
condyle. 
The type and only specimen known is the animal men- 
tioned by Gray (P. Z. S. 1864, p. 57) and by Sclater (id. 
p- 100) as being obtained by Capt. Speke, after whom IL 
name the species. 
The type of Golunda pulchella, which is still in the British 
Museum, is the common West-African species with spots, 
and not stripes; the plate (¢.¢. xiul.), stated to be taken 
from a West-Atrican animal, is not in the least like that 
species, but is much more like the animal here described.
