One of the young specimens in the British Museum has only four 
toes on the hind feet ; but the outer toes on one foot appear to have 
been destroyed ; and on the other foot there is a scale where the 
fifth ought to be placed. This may be the normal state of a different 
species. 
Phe skull which Giebel figures as that of D. villosus, Burmeister, 
evidently belongs to this species.
