Skull robust, more slender in the facial region, sides of muzzle 

 concave; a pair of small prenasals (7 mm. in length) are separated 

 from the nasals by a transverse suture. Nasals expanded behind, 

 gently bowed in the middle, narrowest anteriorly : posterior suture 

 somewhat recurved. Ascending processes of premaxilla; slightly 

 broadened above, premaxillo-maxillary suture but little inclined. 

 Naso-premaxillar}'^ short, little more than two-thirds the length 

 of the naso-maxillary suture. Interorbital space narrow and 

 concave. Frontal region not swollen. Fronto-parietal sutures 

 produced backwards until they meet in a very acute angle. The 

 median frontal suture does not reach this point, but at a distance 

 of 1 mm. is inteiTupted by a distinct transverse suture which 

 thus forms a small postfrontal. Temporal crests defined but not 

 prominent. Interparietal large; its anterior suture forms a 

 straight lime. Foramen magnum broader than high. 



Teeth. — The teeth are generally similar to those of D. lumhoUzi. 

 The canines are larger than I- and the main crest of the premolar
