The species is very distinct in its colouring from the young of any 
of the other Indian species; and the colouring of the young animal 
forms one of the best characters of the species of the genus. It is

not rings, and the head is olive, dotted with black.

Hab, Cambojia (M. Mouhot). 
M. Mouhot sent also specimens of Yestudo elongata, Geoemyda 
spinosa, Emys crassicollis, and of three other species of Emyde ; 
but the three latter are so young as not to be fit to describe, or to 
determine if they are the young of already known species.
