In its general colour it greatly resembles some of the more rufous 
examples of Arvicola amphibia, the fur being deep dusky at the root, 
tipped with rufous-brown, and with a slight mixture of black hairs. 
The under parts resemble the upper, except in being a little paler.

Of aspecimen apparently referable to this species, but a little 
smaller than the one which furnished the dimensions given by Dr. 
Wagner, Mr. Fraser speaks thus :—‘“‘ From Pallatanga ; 2 by dissec- 
tion; native name Guatusa.”’

&c., 1841; Waterh. Mam. ii. p. 387. 
In the various works on Mammals of South America to which I 
have access, I do not find this species mentioned, and neither is it 
included in the general work on Mammalia by Dr. Wagner, so that I 
conclude that it must be rare. Mr. Waterhouse refers to the original 
description, and to two specimens in the Leyden Museum, a description 
of which he gives ; and as in this, as well as in other cases when pro- 
vided with sufficient materials, he leaves little to be desired, I refrain 
from further description, except to add, that the species may be at once 
recognized by its colour, which bears some resemblance to that of the 
common Badger. The following note accompanying the specimen 
is of interest :—‘‘From Pallatanga, 2 by dissection. Native name 
Guatusa. Irides greyish brown. Shot near the house in the day- 
time: two young in the abdomen, one a male and the other a fe- 
male, quite naked, about 3 inches in length.”
