MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 559 



of skull 133, 132.7; condyloincisive length 130.8, 133.5; greatest width 

 across zygomatic arches 77.6, 78.2; least interorbital mdth 28.5, 

 29.7; wddth of rostrum at level of canines 37.8, 39.4; width of palate 

 at level of last molars 42.0, 42.7. 



Remarks: The skull of the aard wolf is small and the muzzle is 

 quite blunt. The premolars and molars are reduced to mere pegs 

 and the toothrows are virtually parallel. By these means it may be 

 distinguished from the genus Hyaena which it resembles externally. 

 However, the ears are longer, the legs are shorter, and in old animals 

 the mane reaches farther posteriorly than in Hyaena. 



Subfamily Hyaeninae

Crocuta crocuta fortis J. A. Allen, Bull. Amer. Mus. Nat. Hist., vol. 47, p. 214, 

 Apr. 11, 1924. (Faradje, Belgian Congo.) 



Specimens Examined: Five, all in BM, from: Kulme, Wadi Aribo, 

 1; Meshra Zeraf, 1; northern Darfur, 1; Bahr Zeraf, 1; Kaka, 1. 



Measurements: Cranial measurements of an adult male from 

 Kaka and an adult female from Meshra Zeraf are, respectively, as 

 follows: Greatest length of skull 257, 273; condyloincisive length 240, 

 250; greatest width across zygomatic arches 152, 176; least interorbital 

 width 54.5, 64.0; greatest length of fourth upper premolar 36.6, 37.3. 



Remarks: The spotted hyaena may be distinguished readily from 

 the striped hyaena by the pattern of the pelage. In addition, the 

 skulls are separable by means of the larger and more inflated auditory 

 bullae, the wider posterior choanae, and the much larger and wider 

 upper fourth premolar.
