Mammalia of Southern Brazil. 139 
In the following measurements some allowance must be made 
for stretching of the skin. 
Measurements of skin. 
This species seems to be nearer to the D. 
D prymiiolopha. Unfortunately I can find no skeleton or skull per- 
taining to the type, so that I can not describe their characters. It 
is much larger than the former species, exceeding it by more than 
six inches. Its uniform coloration is also entirely peculiar in the 
genus, for the hairs are not annulated. The feet are relatively much 
shorter than in the D. croconota; for according to Waterhouse, with 
a total length of 17 in. 9 lines, the feet of the latter measure (minus 
the nails) 3 in. 5 lines which is identical with the length of the foot 
m D. aurea, with a total of twenty-four inches. The head is the 
D. croconota measures 3 in. 11 lines. The relationships of the D. ra- 
rea appear to be with the D. azarce.
