Pernambuco. He adds the suspicion, that they miglit repre- 

 sent Nasua rufa Desmarest. This is undoubtedly true, but 

 this is identical with Nania nasua Lin. He believed also, 

 that the only difference consisted in the reddish colour, and 

 as he bad a strong impression of the variability of the Coatis 

 at the same time as he had observed that »Gelb und Roth 

 gehen schon individuell in einander iiber, wie ich bei Mycetes 

 und Sphiggurus erwähnt habe», he did not pay any more 

 importance to it. There is, however, no doubt that there 

 are two different kinds of Coatis in Brazil viz. the northern 

 rufous, comparatively short-haired Nasua nasua Lin., and 

 the southern more buffy, greyish grizzled and more furry one, 

 which I venture to name Nasua henselii. These may be 

 distinguished in the following way: 



Nasua nasua Lin. 



General colour more or less rufous^, often entirely rufous 

 only with the snout greyish, the face blackish, grizzled, 

 posterior side of ears black, the feeb blackish and the tail 

 ringed with blackish. In other cases there are very long 

 black tips to the hairs of the upper parts which may domi- 

 nate on the back. If at the same time the rufous colour 

 has faded to buff the appearance of the animal is much 

 different, but the tips of the hairs are always black. The 

 amount of black varies much, but often there are blackish 

 streaks extending from the ears backwards bordering the 

 more or less rufous or buff sides of the neck. The lower 

 side is more or less rufous or buff with the chin white. The 

 tail is ringed at least on the lower side, if the black on the 

 upper is continuous, and the rings may sometimes become 

 whitish on the lower side. The three light spöts in the orbital 

 region are as a rule present, but not large, sometimes partly 

 obsolete. The upper lip is only narrowly, or not at all 

 bordered with white behind. The fur is harsh and compa- 

 ratively short about 1 V2— 2 cm. on the sides, 2 V2 or even- 

 tually 3 cm. on the back. For cranial measurements see table.
