JIab. Naivaslia, British East Africa. 



Ti/pe. In British Museum, no. 0. 6. 21. 3-4. 



Mr. Kemp, during JMr. C. D. Rudd's Expedition in British 

 East Africa, collected a large series of this form at Baringo 

 and Eumruti (Laikipia Plateau). A specimen from Xandi, 

 also collected by Mr. Kemp, ui doubtcily represents the same 

 race, so that it is evident tliat jrrcece/'S is wid<*lj distributed 

 over this part of East Africa. 



(12) ArvicaniMs abi/ssmicus neumnnni, Matsch. 

 Mus neumanni, Matscliie, SB. Ges. naturf. Fr. Berl. 1894, p. 204. 



In size about equal to nairohce, but darker and more ochra- 

 ceous in colour ; evidently closely allied to both nairohce and 

 prccceps. 



Size of body and tail about as in nairohce; hind foot 

 rather smaller, average length 2G mm. General colour like 

 that of prteceps, but richer and darker in colour, the black 

 ground-colour move evident and washed with ochraceous 

 buff, the reddish tint paling on the flanks to yellowish buff. 

 No trace of dorsal stripe. Backs of hands and feet brownish, 

 speckled with buff. Underparts as in prccceps. Tail like 

 that of nairohcE. 



Skull rather smaller than in the other races of abi/ssinicus. 

 Auditory bullae less inflated than in pracpps or nairohtv. 



Dimeu'^ious in millimetres (measured in the flesh) : — 



Average of 



7 adults. Max. Miu. 



Head and body 139 149 132 



Tail ' 106 111 101 



Hind foot 20 27 25-5 



Adult skull : greatest length 32"8 mm. ; basilar length 

 27'0; condylo-incisive length ol"5 ; zygomatic breadth 17 ; 

 interorbital constriction 4'8 ; squamosal breadth of cranium 13; 

 length of nasals 12"4; palatilar length 15; length of palatal 

 foramina ()'^ ; alveolar length of upper molar series 6"3. 



I'ype locality. Burunge, Irangi, south of Kilimanjaro. 



The above description is taken from a series of specimens 

 recently collected by Mr. Kemp at Taveta, Kilimanjaro. 

 This southern race was also represented in a collection from 

 Yoi ; so it is evident that the distribution of neumanni qx- 

 tcnds eastwards from Kilimanjaro towards the coast and 

 southwards towards ^Ipapua. 



The three forms nairohce, pracep!!, and ncunuDnii appt?ar to 

 be very closely relat-.d to one another, as would be expected
