Breadth of skull between the openings 

 of the ear 8 mm 9 mm 



Length of dental series in upper 

 jaw 7,5 „ 9,5 „ 



Length of dental series in lower jaw . 7 „ 8,5 „ 



The nasalia are rather broad behind, and the suture with the 

 froutalia forms a high but rounded angle (open in front). 



The frontalia are without Processus orbitales; the interorbital 

 Space is flat, almost concave, and relatively broadest in the young 

 female. 



The parietalia are in the young female almost flat and smooth, 

 in the male arched. In the latter an extremely fine sagittal crest 

 extends backwards, and joins the somewhat more distinct occipital 

 crest. 



The buUae osseae are of medium size, and are contracted in the 

 middle ; the pars mastoidea is (as in the preceding species) inflated to 

 a secundary bulla, which is nearly as large as the auditory bulla, and 

 like it, is contracted in the middle. 



The palatina have traces of narrow foramina between m^ and m^. 



The teeth. The dentition is normal in both specimeus: 

 « I, c I, i? I, m I (46). 



In the Upper jaw the two central incisors are somewhat longer 

 and stronger than the others, and directed obliquely outwards; the 

 other three incisors are equal in size. 



The canine in the male is long and curved, in the female lower 

 and not bent; it is close to the premolars. 



The premolars increase in size, so that i? ^ is smallest, and scar- 

 cely larger than i*, p^ the largest, and with the middle cusp as high 

 as the nearest molar; in the female it is lower. 



The molars are sharply pointed, especially in the young female; 

 m ^ and m ^ are the largest. 



In the lower jaw all the teeth, as in the preceding species, form 

 an unbroken series. The central incisors are a little broader than 

 the other. 



The premolars are small, the central one the longest ; ^ "^ is the 

 smallest, considerably smaller than p^.
