 Although both the long and the short tailed Aguaras 

 appear to be at least in part mixed in that semi-

 aspect, disposition, and the form of their pupils, 

 they appear to stand more nearly identified than 

 the second with the diurnal dogs of the Old World. 



* We find, from late information, that within the last 

 tliirty-five years the indigenous dogs of the Indians have been 

 gradually replaced by the domestic European, and that now it 

 is difficult to find any even in the more remote parts of the 

 interior. Wlten we were in the country, thia wiw not tba 

 case.
