The Tayra of Tucuman is consequently different from 

 its northern neighbour in Bolivia not only with regard to co- 

 lour, but a] so in dimensions as well, and it appears thus cörrect 

 to distinguish it with a subspecific name. 



Tayra bärbara poliocephala Traill. 



When studying the Tayras in British Museum I found 

 a set of specimens from Guiana which very readily distinguish- 

 ed themselves from all the remainder. 



An old specimen, the skin of which plainly shows that it 

 is a male, may be taken as typical for this race. It is from Bona- 

 sica, Brit. Guiana, collected and presented by F. V. Mc Connell. 

 Its number is 12. 6. 5. 40. 



This animal has the body dark blackish brown, quite 

 black along the middle of the back, so that an indistinct dor- 

 sal band is formed; tail and feet almost black. Head and 

 neck, with a sharp line of demarcation from the back, hoary 

 grey. This colour is produced by the visible parts of the long 

 hairs being white (or whitish) with blackish tips, and partly 

 the dark underfur being visible between the long white hairs. 

 All the hairs of the upper and lateral surfaces of the neck are 

 reversed, but independently on each side, and partly point- 

 ed upwards so that a seam is formed mesially. The hair of the 

 nape with normal direction forms an angular point towards 

 this seam. The nose up to the interocular region is uniformly 

 blackish brown contrasting with the remainder of the head. 

 Back of ears light brownish grey. Chin and interramial space 

 dark brown. The grizzled colour of the head extends down- 

 wards to the lower side, but the large white throat patch is 

 margined anteriorly with a blackish band. This white patch 

 covers not only the whole throat, but also the chest and ex- 

 tends as a band between the före legs. It is almost pure white 

 with very slight yellowish tinge, less than in other Tayras.
