sembling A. harbnrus, L., but blacker in tone and tlie stripes 

 narrower. Central dorsal stripe blaek-brown ; tlie rei^ion 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 tew light-coloured hairs intermixed, 

 the light stripes buti'-white, every second one being ratiier 

 more conspicuous ; the stripes get rather more broken noaring 

 tlie 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. hirharus; 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 bu(F-wliite, 

 claws brown.

 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. j^ulchella. 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. ^5. 1864, p. 57) and by Sclater (id. 

 p. 100) as being obtained by Capt. Speke, after whom 1 

 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 {t. c. xiii.), stated to be taken 

 from a West-African animal, is not in the least like that 

 species, but is much more like the animal here described.
