APRIL, 1914. MAMMALS or NORTHERN PERU OSGOOD 175 



Felis onca Linnaeus. JAGUAR. 



A skull of an adult male secured at Moyobamba shows some char- 

 acters when compared with specimens from Guiana and northern Brazil. 

 With an equally heavy dentition, the skull has smaller general dimen- 

 sions but thicker heavier parts. A short broad braincase, heavy post- 

 orbital processes, almost uniformly broad nasals, and small anterior 

 nares are among its peculiarities. When sufficient material is accumu- 

 lated for revision of the jaguars, it is probable that a race from the 

 eastern base of the Andes will prove recognizable. For such a race, 

 the name Felis onca peruviana Blainville may be available. 



Jaguars range up to an elevation of at least 7,000 feet in the eastern 

 Andes, but in the region traversed by us they are not particularly 

 common. Tracks were seen at Tambo Yaku and at several points in 

 the forest between Moyobamba and Balsapuerto. 



Felis puma Molina. PUMA. 



In the mountains of western Peru, the puma is said to be fairly 

 common and as elsewhere strongly addicted to the habit of preying on 

 live stock. Our attempt to secure one at Hacienda Llagueda with a 

 small and scarcely trained pack of dogs was unsuccessful. This was 

 largely on account of the very steep precipitous canyons which were 

 for the most part quite impassable for horsemen. During our stay at 

 Hacienda Limon a sheep was killed by a puma and the carcass was 

 poisoned in the hope of disposing of the offender but without result. 

 In the eastern montagna region from Moyobamba to Yurimaguas we 

 received occasional reports of the puma. 



Felis wiedi Schinz. MAXIMILIAN'S TIGER CAT. 



One specimen : Moyobamba. 



Although slightly immature, this example shows by the reversed fur 

 on the neck and by its dimensions that it represents Felis wiedi or a 

 very closely allied form. The fur is long (20-22 mm. on middle of 

 back), thick, and very soft. From the occiput to the shoulders there 

 are but three narrow black lines, the middle one divided posteriorly. 

 The tail has but nine black rings, slightly wider than the fulvous spaces 

 between them. Flesh measurements are: Total length 820; head and 

 body 465; tail 355; hind foot 125. 



We had only scattering reports of small cats in the region from 

 Moyobamba westward and saw very few skins in the possession of the 

 natives. From Moyobamba eastward they are more common.
