in the dim light in thick bush they look more like an indistinct greenish shadow 
than a living animal and disappear very quickly out of sight.

Five specimens of Scrub Squirrels were collected in the neighbourhood of Meru 
boma and the native village Kanyakeni, where they mostly were found in the shambas, 
which were surrounded by hedges and contained small trees planted to support the 
yams-vines. These specimens looked when alive very much like those collected around 
Nairobi. A closer examination reveals, however, that the Meru Scrub Squirrel which 
HELLER recently has named P. kahari has a considerably smaller skull, with shorter, 
less constrieted preorbital region, narrower occipital region, shorter diastema and so on. 
For comparison a few measurements of a skull from Nairobi and another of 
similar age from Meru boma are given:

On the southern side of Guaso Nyiri I observed Ground Squirrels in a patch 
of thornbush, but I could not obtain any specimens there. On the northern side of 
the same river they were more common, and I collected eight specimens at Njoro 
and other places, even below Chanler Falls. 
My specimens agree with the description of X. rufifrons which DOLLMAN has 
based on specimens obtained in the same localities in which short time afterwards I 
collected some of mine. But, of course, there is some variation in colour even among 
specimens caught at exactly the same place. Some specimens are entirely pinkish 
brown (conf. below) all over back and sides. with hardly any blackish sprinkling at 
all visible, not even on the back of the head, and with no difference whatever
