wanting, and birds were very scarce, several species of doves being 

 almost the only ones seen. 



Although advised by the natives that the early morning was the best 

 time for hunting, we sighted a pair of bears at midday apparently active 

 and feeding in the full glare of the tropical sun. They were on a low 

 bench just above the boulder strewn playa or dry stream bed along the 

 opposite side of which we were picking our way at a distance of about 

 half a mile. They might have been overlooked if one of them had 

 not drawn our attention by standing erect. After a rapid chase, during 

 which a couple good dogs were of much assistance, the female bear was 

 killed while the other, presumably a male, was only slightly wounded 

 and made its escape. 



From reports received from local sources, it is evident that bears 

 are fairly common in numerous localities in the arid region similar to 

 the one in which we found them. That the bears of this region can be 

 the same species or subspecies as those of the forested regions of eastern 

 Pent does not seem probable, but without specimens of both sexes from 

 both regions the matter remains doubtful. 



It is even possible, as suggested by Tschudi, 1 that the original type 

 of Ursus ornatus came from this region by way of Trujillo in spite of 

 F. Cuvier's statement that it came from Chile. Certain it is that it 

 must always have been an easy matter to bring living bears into Trujillo, 

 whereas specimens from Chile have been recorded but rarely if at all.

Only lack of time prevented our obtaining a series of this species, for 

 it was fairly common and not difficult to trap. Tracks were seen daily 

 leading up and down the paths about the cane fields, in the sandy stream 

 beds, and occasionally out on the open desert at considerable distance 

 from water. Small ground doves which abound evidently are the 

 favorite prey of the foxes.

The canids of southern Chile, Patagonia, and Tierra del Fuego have 

 long been known to be of two general types, one small and foxlike, the 

 other larger and more wolflike, although still somewhat smaller than a
