ORDER RODENTIA. 249 



confinement, few animals exhibit more obtuseness of in- 

 telligence ; it sleeps a great deal ; is, however, extremely 

 cleanly in its habits ; collects all the straw, hay, and herbage 

 it can procure for a bed, and is particularly careful to keep 

 it clean. Like most other animals deficient in intelligence, 

 it is strongly endowed with instinct. 



The Yellow Paca seems to differ from the Brown in no- 

 thing but the ground colour of the fur, which is reddish- 

 yellow. It has not, like the other species, been observed 

 in Paraguay.
