dark, blackish brown above and below, almost black on hind- 

 quarters; head and neck dark umber brown, shading gradually 

 without any line of demarcation into the colour of the back. 

 The ears are somewhat lighter brown than the head. The tail 

 is quite black, less bushy than in the typical T. bärbara. 



The hair is everywhere adpressed. On the withers it is 

 hardly more than 5 — 6 mm in length, on the posterior back 

 15 — 16 mm, and on the tail about 24 — 27 mm. 



On the label the following measurements are stated:

The occipital crest is well developed posteriorly, but its 

 greatest height hardly reaches 7 mm. The zygomatic arches 

 are of moderate thickness, their vertical diameter being about 

 4,5 mm. 



The shortness of the fur of this race makes it easily re- 

 cognisable. 



There are also some more specimens of Tayra from diffe- 

 rent parts of Brazil in British Museum and among them the 

 typical Tayra bärbara ought to be found. But there is also a
