" This species is very common here, and one may see their rude 

 nests at the foot of bushes everywhere. Besides these nests they 

 make a good many burrows. They are sometimes gregarious, as I 

 have seen fourteen killed at one place. They often have five young. 

 They are very fierce and bite severely." — W. T. 



The present is the most southerly locality that has been yet recorded 

 for this species. The specimens differ from the ordinary northern 

 ones in their slender feet and less densely pilous soles, but do not 

 appear to be specifically or even varietally separable,

" This species is abundant in the neighbourhood. It varies greatly 

 in colour, from whitish grey to the colour of old mahogany ; but 

 the colours of the underparts and feet are constant. The lightest 

 specimens I have seen were caught in December. Its weight is 

 about three times that of O. taylori." — W. T.
