S 232, 233, 236, 2 234. 15 miles north-east of Ching-ning Chou,

A very common and widely distributed species. 
Eutamias asiaticus ordinalis, Thomas. 
g 118. Yii-lin Fu, Shensi. 
A pale desert race found round the borders of the Ordos Desert, 
where it inhabits the deep ravines, which take the place of loess gullies 
further south and east. It has not been recorded from the desert itself. 
It might be noted that specimen No. 185 of the preceeding species 
closely resembles in the lightness and yellowness of its pelt E. a. ordinalis. 
Similar agencies may have been at work in both cases to cause this 
lightening of colour, for specimen No. 185 was taken close to country, 
which bore some resemblance to that round, and in, the Ordos. Wide 
stretches of flat, somewhat sandy land, was there, inhabited chiefly by 
Citellus mongolicus, and Lepus swinhoet subluteus, two other Ordos forms. _
