CANIS JUBATTJS. 23 



of the under surface of the lower jaw. There is also a black patch on the 

 front of the lower part of each fore leg, and also from the heel down- 

 wards, on the middle of the posterior part. There is a good deal of 

 black about the jaws generally, but the upper surfaces of the toes are 

 clothed with whitish hairs. There are also many black hairs about the 

 head. The front of the upper part of the throat and the hinder part 

 of the under surface of the lower jaw are white. There are long white 

 hairs within the ears, and a tuft of white hairs terminates the tail. The 

 rest of the body is of a reddish-yellow colour, which may be darker across 

 the shoulders, along the middle of the back, and on the outside of the 

 ears. 



The coloration of this animal is evidently subject to variation. The 

 specimen figured by Burmeister is much more dull in colour than that 

 represented by us, or than is shown in the plate in the ' Proceedings of 

 the Zoological Society.' The latter has white around the mouth, no 

 white patch on the front of the throat, and no transverse darkening 

 across the shoulders. Burmeister's specimen has the white throat, but 

 immediately beneath is a curiously shaped longitudinal black patch 

 (wanting in our specimen arid that figured by the Zoological Society) 

 passing downwards and backwards, ending in a point on the front of 

 the chest. The muzzle also is black. 



Habitat. Brazil, Paraguay, and probably Uruguay and the northern 

 parts of the Argentine Republic.

Skeletal and Dental Characters and Dimensions. 



The skull is much elongated, and the angle of the mandible very small. 

 The fourth upper premolar is exceptionally short, and the two true upper 

 molars, taken together, exceptionally long in proportion. 



Our woodcut is a representation of the skull which was extracted 

 from the skin we have had figured.
