Dr. Pickering observes with reference to this animal : 

 " From information derived from residents, I am inclined to suppose 

 that the native country of the ' cuy' or guinea pig, extends to the 

 mountains or forests of Eastern Peru, and is not exclusively Guiana 

 or Brazil, as has been supposed. It is a common domestic animal 

 throughout Peru."

In relation to this species, we introduce the following from tlie 

 journal of Dr. Pickering : 



" This animal is very common on all the barren stony hills of 

 Western Peru, even in the immediate vicinity of Lima, — so much so 

 that it is ditficult to determine how it finds sustenance, unless it re- 

 sorts to roots, for instance, the deep-buried bulbs of the AmaryUls 

 tribe.
