The specific reference of figs. 4 and 6 is open to a considerable amount of doubt — Fig. 7 was 
obtained from the lower Siwaliks of Gandoi, Bugti Hills ; all the others came from the same deposits of 
Dera Bugti. All the figures are of the natural size ; the upper teeth being viewed from the inner, and the 
lower from the outer side of the grinding surface ; a, larger accessory column (posterior in lower, and 
anterior in upper teeth) ; b, smaller do. (anterior in lower, and posterior in upper teeth) ; ta, hind talon ; 
iu, tubercle at extremities of transverse valleys (outer in lower, and inner in upper teeth).
