Nasua henseli n. sp. 



General colour grizzled buffish grey, which colour is 

 produced in sucli a way that the basally påle brown or 

 brownish white long hairs have broad subapical black rings 

 and then again buffish tips. (The pattern of the hairs thus 

 qaite different!) The snout is black or blackish, the white 

 börder of the upper lip is broader and better developed than 

 in N. nasua. The three orbital markings are large and white. 

 The black of the cheeks extends to above the eye in front 

 of the supraorbital spöt and is bordered from the buffish 

 or grizzled forehead by a white band. Ears black broadly 

 bordered with white along the inner margin. Sides of neck 

 creamy or påle buffish. Chin white, lower parts otherwise 

 buffy or brownish buffy. Feet black. Tail ringed with 

 black and the dorsal colour, the påle rings on the lower side 

 sometimes whitish, the tip largely black. The fur is less 

 harsh and all över much thicker than in N. nasua, generally 

 about 3 Va— 4 cm. 



For examination I have had three adult males from S:a 

 Catharina, S. Brazil, which place may regarded as type lo- 

 cality. 



The cranial measurements of an adult male (the oldest, 

 but the smallest of the three!) are recorded in the table 

 for comparison with those of N. nasua. It may be seen 

 from these, that the skull of the Coati from Southern Brazil 

 is considerably longer than that of N. nasua. It is also 

 corroborated by Hensel's statements^ that among 34 skulls 

 of old males the maximum basilar (Hensel!) length was 126, 

 the minimum 112, and tbe average for normal skulls 118 

 mm. Thus the minimum is considerably more than the 

 maximum in N. nasua. It can also be seen from the table 

 of measurements, that it is chiefly the longitudinal dimen- 

 sions which are larger than in N. nasua, while the latitu- 

 dinal ones show less absolute difference. By this fact the 

 general shape of the skull of N. henselii becomes rather dif- 

 ferent from that of N. nasua, and the rostrum of the former 

 looks longer and narrower, especially, because the nasals of
