The type of this form died in the Menagerie of the Jardin des 

 Plantes, and was described by Pucheran (1. c). In having the three 

 stripes on the head it is nearer trivirgatus and rufipes, than vocif- 

 ERANS. It is a plain little animal, a dull grayish brown constittUing 

 the general color of its coat. The under parts were probably a deeper 

 yellow, as the hair is faded, not only beneath but over the body 

 generally, and originally it was probably considerably darker. The 

 golden dorsal line, broadest on the lower part of the back, distinguishes 

 this form from rufipes and trivirgatus, which have this part reddish 

 and chestnut respectively. The continuation of the lateral stripes to 

 the throat where they meet, also distinguishes this species from all 

 others. The stripes from mouth across the throat, while of the same 

 color as the lateral ones on the head, are fainter.
