MAMMALS OF ANGLO-EGYPTIAN SUDAN — SETZER 579 



the Guaso Ngisliii Plateau, British East Africa, is quite strilving. 

 The color of the pelage ranges from a pale buff to a strong reddish 

 cinnamon, yet the skulls appear to be quite uniform in their charac- 

 teristics. The specimens from Nimule and Torit show this same 

 amount of variation in color and the same degi-ee of uniformity of 

 cranial characters. 



While no specimens have been seen from Gondokoro, specimens 

 compared to the type of aeguatoria from Nimule and Torit show no 

 differences, and those specimens, in turn, compared to material from 

 Mongalla Province show no dissimilarities. Therefore, I feel that the 

 name 0. o. ugandae should fall as a synonym of the earlier aeguatoria. 



Ourebia ourebi montana (Crctzschniar) 



Antilope montana Cretzschmar, iu Ruppeil, Atlas zu der Reise im nordlichen 

 Afrika von Ruppeil, pt. 1, Saugethiere, p. 11, pi. 3, 1826. (Fazogli Hills, 

 Blue Nile.) 



Ant[ilope] brevicaudata Riippell, Neue Wirbelthiere zu der Fauna von Abyssinien 

 gehorig, Saugethiere, p. 25, 1835. (Sennaar.) 



Specimens Examined: Thirteen, all in BM, from: Between Tonga 

 and Lake No, 1 ; 100 miles northeast of Bor, 1 ; White Nile, about lat. 

 11° N., 2; 5 miles west of Rumbek, 1; Kamisa, Binder River, 1; 

 Upper Nile, 1; Kornook, 1; 18 miles southwest of Shambe, 1; 8 miles 

 south of Tonga, 3; halfway between 1st and 2d resthouses on way to 

 Meshra, 1. 



Remarks: In only a cursory examination of the ungulates of the 

 Sudan, it is apparent that they all need a vast amount of work done 

 on them. In Ourebia, particularl}'', there are many striking similarities 

 between the subspecies. It may well be that when they are studied 

 in more exacting detail montana will be found to be the name to be 

 applied to all of the eastern and southern Sudanese oribis. 



Rhynchotragus guentheri sinithii (Thomas) 



Madoqua guentheri smithii Thomas, Proc. Zool. Soc. London (1900), p. 804, Apr. 1, 

 1901. (About 30 miles southeast of Lake Stephanie, Ethiopian Border.) 



Specimens Examined: Twelve, from: Ikoto, 8; Torit, 3;Latuka 

 Mountains, 1 (BM). 



Remarks: The long-snouted dikdiks are apparently found only in 

 the extreme southeastern Sudan in open savanna country. 



Notes on Oazella 



The genus Gazella, in the Sudan, is divided into two subgenera. 

 The typical subgenus, Gazella, is distinguished by the following: Fe- 

 males bearing weU developed horns; body size small or medium; and 

 white of rump not intruding far into fawn color of body. The species
