plate. In my specimens the colour of the parts mentioned varies from the palest 

 maize-yellow to rather pronounced orange- yellow. Sometimes this yellow tinge extends 

 all over the throat, but oftener the latter is white in the middle. 



Considering the variation I think it is difficult to maintain any difference be- 

 tween X. dabagala and rufifrons. 



The cranial measurements agree with those recorded by Dollman in the largest 

 specimens, but some fully adult are a little smaller.

These Ground Squirrels lived in colonies and are rather shy. Their general 

 colour agreed very well with the reddish gravel, and in the glare of the sun it was 

 not easy to follow their movements with the eye, when they had been disturbed and 

 ran for their holes. The vegetation around the colonies was always very scanty 

 because the Squirrels had eaten almost everything palatable to them. The locaUty 

 of a colony could therefore be detected already before any burrows had been seen. 

 Sometimes a colony of Helogale was found at the same place.

A specimen caught at Kutu (between Fort Hall and Embu boma) 'Vi 1911 

 agrees with regard to dimensions and colour with Osgood's description except that 

 the blackish area around the eye is only little developed and not well defined. .The 

 skull is unfortunately broken so that all skull characters cannot be verified, but 

 those about which information can be obtained are in accordance with the descrip- 

 tion of the type which is from »Ulu Kenya Hills, British East Africa.
