DotiMAN has named the race occurring on the Aberdare Range and on Kenia 
L. zena.* The difference from the typical LZ. 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.

A specimen of this interesting Rat was trapped */: at Luazomela river, a tribu- 
tary from the south to Guaso Nyiri. It agrees with HrLuEr’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.

Four specimens of this comparatively short-tailed Spiny Mouse were caught not 
quite a week later than DoLuMAn’s type viz. °/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 DoLuMan’s type viz. 
measuring in total length 23,2 mm. (¢), 23,4 mm. (2) and 23,5 mm (@). 
The last of these has:

Length of nasals.. bacco of Jdpins all Sadi dupie 
Length of upper molar series . . . . . 3,7 (3,8) mm. 
These measurements except the last are somewhat larger than those recorded 
by DoLiMAN, and it is thus probable that his type specimen was not quite fullgrown. 
It appears uncertain whether this Spiny Mouse should be regarded to be any- 
thing more than a geographic, less rufous subspecies of A. wilsont 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 Doriman’s paper.
