Remarks: The reedbuck is apparently rather widely distributed 

 over the southern portion of the Sudan to about lat. 15° N. The 

 favored habitat seems to be heavy reeds near watercourses. 



Hippotragus equinus bakeri Heuglia 



Hippotragus bakeri Heuglin, Nova Acta Acad. Caes. Leop. -Carol., Jena, vol. 30, 

 No. 2, p. 16, 1863. (Between upper Atbara and Bahr-el-Salaam Rivers, 

 near Abyssinian border.) 



Hippotragus equinus doggetti de Beaux, Ann. Mus. Civ. Stor. Nat. Genova, ser. 3, 

 vol. 9, p. 231, Jul}- 10, 1921. (Near Gondokoro.) 



Specimens ExA^^XED: Thu-teen, from: T^Ieshra Zeraf, 3 (BM); 

 Dinder River, 1 (BM) ; Binder Valley, 1 (BM) ; Rejaf, 1 ; Gondokoro, 

 3; 60 miles north of Nimule, 2; Torit, 2. 



Remarks: The roan antelope apparent!}" ranges over the southeast 

 quarter of the Sudan. 



The specimens from the Dinder River area are virtual topotypes 

 of bakeri. I can discern no differences between these animals and ones 

 from Gondokoro which are topotypes of dogetti. Therefore, I am 

 referrmg all the roan antelopes from the south and southeastern 

 Sudan to the earlier named bakeri. 



Oryx dammah (Cretzschmar) 



Antelope dammah Cretzschmar, in Riippell, Atlas zu der Reise im nordlichen 

 Afrika von Ruppell, pt. 1, Saugethiere, p. 22, 1826. ("Probably Kordofan," 

 Haraza, eastern Anglo-Egj^ptian Sudan.) 



A[ntilope] tao H. Smith, in Griffith, The animal kingdom ... by the Baron 

 Cuvier . . . , vol. 4, p. 189, vol. 5, p. 327, 1827. ("Some days Journey's dis- 

 tance from the Bahr-el-Abiad.") 



Antilope algazeUa Ruppell, Neue Wirbelthiere zu der Fauna von Abyssinien 

 gehorig, Saugethiere, p. 26, 1835. (Plains of Nubia to Fayum, Egypt.) 



Specimen Examined: One, in BM, from Sennaar. 



Remarks: The nomenclature of the scimitar oryx has been com- 

 pounded in confusion. Ellerman and ^lorrison-Scott (1951, p. 385) 

 regard Oken's names of 1816 to be untenable. With this, I agree. 

 The next available name then, according to the above authors, is 

 Antilope tao H. Smith, 1827, to replace algazel Oken, 1816. They 

 further conclude that the northern African representatives of the 

 oryx are not only congeneric but that they represent a monot3T)e 

 species. I can find no disagreement vdih the latter conclusion. 

 These authors, however, overlooked the earher name dammah Cretz- 

 schmar, 1826, for the scimitar oryx, and since it is conceded that these 

 animals are a monotypic species the name should thus stand as Oryx 

 dammah Cretzschmar.
