expressed as " Wa-ah, wah, wah, wah," and when exaraiuing some 

 suspicious-looking object it gives out a low growl ending in a 

 suppressed bark. 



The skull is short and strong, and the muzzle much broader than 

 in C. variegatus ; the squamosal portions of the zygomata are very 

 much expanded ; the nasal bones are short, being almost invariably 

 shorter than the maxillary processes ; there is a deep depression 

 in the middle line of the very broad forehead ; the carnassial 

 teeth are very powerful and much larger than those of C. lateralis. 

 O. variegatus seems to me to be the only Jackal of which the skull 

 can possibly be confused with that of this species, but not only the 

 muzzle but the skull throughout is much narrower in proportion 

 to its length. 



I give simple length and breadth measurements (in millim.) of 

 the largest and smallest entire skulls of these two species that 

 have come under my notice : —
