The skull. A B 



Length of skull V 80 mm 



Length of lower jaw 49 mm 63 mm 



Neitlier of the two skulls are complete. A is a young specimen; 

 all the bones are loosely connected and partly wanting. B represents 

 a mature individual; the bones have prominent sagittal and occipital 

 crests. 



TheNasalia are in both specimens cut off or rounded behind towards 

 the Frontalia, whilst in D. maculaius (at all events in the older indi- 

 viduals) the suture forms a more or less pointed angle, open in front. 

 The teeth. The dentition is: 



A : i I, c I, i) I, m i (42). 

 B has an supernumerary incisor behind the left i* in the upper 

 jaw. In both specimens the central pair of the upper incisors is 

 slenderer and more pointed than the others , in B also but slightly 

 longer. (In D. maculatus these are all about equal). The molars are 

 complete in both specimens, and in the young more pointed than in 

 the mature specimen. In other respects they are formed as in D. 

 maculatus. 



Length of the dental series: 



A upper jaw 35 mm, lower jaw 33 mm 

 B „ 41 mm, „ 38 mm.

A. Herbert Vale, November 1882 (skiii with skull). 



A skin with skull was sent home from Herbert Vale, secured in 

 November 1882. The skin, in rather bad condition, was determined 

 at the preliminary examination to belong to D. hallucatus; but sub- 

 sequently by an accident it has been lost, and the following remarks, 

 therefore, only concern the skull, 



The skull. The individual was full-grown. All the teeth are 

 developed, the molars of the upper jaw already rather wom, the 

 sagittal and occipital crests sharp. As I have also before me a fully 

 developed individual of D. geoffroyi (with a skull of the length of 80 mm) 

 as well as a younger one, the skull of which is of about the same size 

 as the present specimen of D. hallucatus, I shall point out the diffe- 

 rences which the skulls of these species present. 



Length of skull 63 mm, breadth 37 mm,
