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

 consider it best for the present to distinguish vulturnus as

" 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

The further series of this most beautiful Akodont bears out 

 the distinction of sodalis from true Bolivian bacchante by the 

 greater paleness of its general colour.
