OF THE PENINSULAR REGION. 43 



Family TKAGULIDiE. 



(The Chevrotains or Mouse-deer). 



Genus Tragulus. 



The Mouse-deer are small animals, entirely hornless but 

 with long sharp canines present in the upper jaw of the males. 

 The lateral horny toes are well-developed and there is a bare 

 glandular patch on the under-side of the mandible. They are 

 forest dwellers of crepuscular habits. 



The animals of this genus form two very distinct groups — 

 the Napu and the Plandok ; the members of the latter being 

 much the smaller in size : their total length (tip of nose to 

 end of tail) being rarely more than the head-and-body length 

 of the others.
