96 EINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



DoLLMAN has named the race occurring on the Aberdare Range and on Kenia 

 L. zena.^ The difference from the typical L. aquilus from Kilimanjaro appears to be 

 very small. More than subspecific rank can impossibly be admitted to L. zena, and 

 intermediate links may be found. The author quoted has also described an allied 

 form (L. rubecula) from Elgon. 



Saccostomus mearnsi Heller. 



Hellee: Smiths. Misc. Coll. Vol. 1910, 54 p. (n:o l924) p. 3. 



A specimen of this interesting Rat was trapped Va at Luazomela river, a tribu- 

 tary from the south to Guaso Nyiri. It agrees with Heller's description and figu- 

 res of the skull. The only difference appears to be that the nasal region of my 

 specimen is slightly narrower, but as it is a female, and the type is recorded to be 

 a male, such a little difference might easily be explained as a sexual variation. 



Acomys ablutus Dollman. 



Dollman: Ann. & Mag. Nat. Hist. Ser. 8, Vol. VIII, p. 127. 



Four specimens of this comparatively short-tailed Spiny Mouse were caught not 

 quite a week later than Dollman's type viz. ^h — '/2 1911 at our camp near Lekiundu 

 river not much south of Guaso Nyiri. This place is situated not far from the type 

 locality »Nyama Yango». 



Three of my specimens have a little larger skulls than Dollman's type viz. 

 measuring in total length 23,2 mm. (c?), 23,4 mm. (?) and 23,5 mm (?). 



The last of these has: 



Condyloincisive length 21,7 mm. 



Zygomatic width 11 ,3 » 



Least interorbital breadth 4,3 » 



Width of braincase 10,7 » 



Length of nasals 9,5 » 



Length of upper molar series 3,7 (3,8) mm. 



These measurements except the last are somewhat larger than those recorded 

 by Dollman, and it is thus probable that his type specimen was not quite fuUgrown. 



It appears uncertain whether this Spiny Mouse should be regarded to be any- 

 thing more than a geographic, less rufous subspecies of A. wilsoni Thomas. 



The country where my specimens were caught is a stony acacia-steppe but at 

 least one of the specimens was trapped among reeds near the little river. 



^ »Nyama Yango» = »my meat», was the name among the natives of the late A. H. Neumann, and his 

 old camp is, undoubtedly, the place meant in Dollmab's paper.
