but of late it has been well protected in the Anglo-Egyptian Sudan 

 and Uganda, and its future there seems assured. A small number 

 survive in the Ubangi-Shari Territory of French Equatorial Africa 

 along the Sudan frontier. 



"The Nile race resembles very closely, in external appearence and 

 size, the southern race .... It differs, however, by the possession 

 of a flatter dorsal outline to the skull . . . and by the smaller size of 

 the teeth. The measurements of skulls of the two races show them to

"The range . . . was believed to be restricted to the Lado country 

 and the immediate neighborhood of the Nile. Contrary to all sur- 

 mises its range has steadily increased. These white rhinoceroses are 

 now positively known to extend from a little north of Lake Albert 

 to three hundred miles down the Nile to a point near Shambe. From 

 there it stretches four hundred and fifty miles westward to the Dar 

 Fertit section, and two hundred miles south to Rafai [on the Bomu 

 River at about long. 24 E.]. The southern limit extends about five 

 hundred miles across the northeastern Uele district to the territory 

 northwest of Lake Albert. This habitat thus forms an oblong area 

 of about 100,000 square miles, all situated west of the Nile." (Lang, 

 1920, p. 76.) This range corresponds more or less to the eastern 

 portion of the Ubangi-Uele Savanna District of Chapin (1932, 

 p. 90) or the Ubangi Savanna District of Bowen (1933, pp. 256, 258) .
