Mammals from Jujuy. 613 



Mr. Simons. Altogether tlie differences do not amount to 

 very much ; but, in view of the wide difference in locality, I 

 consider it best for the present to distinguish vulturnus as 

 species rather than subspecies.

" Not very abundant, and generally isolated from other 

 rodents. More or less aquatic, living on the banks of 

 streams and marshes, and one was caught among reeds on a 

 little islet in a lake. Have their holes under isolated rocks 

 on level ground, and are not found among the stony hills."—

The further series of tliis most beautiful Akodont bears out 

 the distinction of sodalis from true Bolivian bacchante by the 

 greater paleness of its general colour.
