Skull: greatest length 51"5 ; basilar length 43'1 ; greatest

 interparietal 8x12; palate length 24*4; diastema 14; 

 palatal foramina 7'2 ; length of upper molar series 10'3. 



Hab. and Type. As above. 



This fine species appears to be a giant member of the 

 U. Bruijnii group, and to iiave no relationship to tlie long- 

 tailed forms which it approaches in size. 



When U. sapientis was described more empliasis should 

 have been laid on the unusual size of the bullae, which far 

 exceed those of either the large U. macropus and its allies or 

 the small U. Bruijnii. In U. porculiis thej are of the usual 

 minute size.
