MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 571 



Remarks: P. a. bnfo may be distinguished from P. a. aeliani from 

 British East Africa and Ethiopia bj^ the wider upper molars, less 

 inflated auditory bullae, less concavity of the dorsal surface of the 

 skull between the orbits, and the flatter nasals. 



The skull available from Torit is of an immature female of the same 

 age as the type of P. a. bufo. In all characters this skull agrees with 

 the type and dift"ers from P. a. aeliani as above. These characters 

 are not sexual or age variations since they differ to the same degree 

 in animals of comparable age and sex of P. a. aeliani from British 

 East Africa. 



The skull of P. barkeri differs from P. a. aeliani in exactly the same 

 degree and quality as do skulls of P. a. bvfo. Since Rothschild's 

 name is antedated by bufo and since I can detect no differences between 

 bufo and barkeri I am treating the latter as a synonym of the former. 



Family Hippopotamidae

(Nile River, Egj^pt.) 

 (Other synonyms extralimital to the Sudan.) 



Specimens Examined: Two, both in BM, from White Nile. 



Remarks: The hippopotamus was formerly abundant throughout 

 the Nile drainage. It is now extinct north of Khartoum and reduced 

 in numbers throughout the rest of the drainage system except in the 

 great lakes to the south. 



Family Giraffidae 



Giraffa canielopardaUs Linnaeus 



Remarks: Two subspecies of giraffes are supposed to exist in the 

 Sudan. The northern and eastern one is Girarffa camelopardalis 

 camelopardalis Linnaeus, 1758, with the type localitj^ given as "Ethio- 

 pia and Sennar," actually from a captive animal in Cairo, Egypt, 

 assumed to be from the Abyssinian, or Kassala, side of Upper Nubia. 

 The western and southern subspecies has been described as Giraffa 

 camelopardalis antiquorum Jardine, 1835, with the tj^pe locality stated 

 as "Senaar and Darfom-." Other names have been proposed but are 

 now regarded as synonyms of the esLrliev camelopardalis and antiquorum. 



As may be noted, both subspecies share the type locality of Seimaar. 

 This seems highly unreasonable but without a detailed study of the 

 genus it seems that the problem will not be solved. Only two speci-
