ORDER PERISSODACTYLA I ODD-TOED UNGULATES 409 



Distributional maps are provided by Heller (1913, pi. 11), Roose- 

 velt and Heller (1914, vol. 2, p. 671), Lang (1920, p. 77, and 1923, 

 p. 156), and Lavauden (1933, pi. facing p. 24, and 1934, p. 431, 

 fig. 45). 



Anglo-Egyptian Sudan. "By his account published in 1869 von 

 Heuglin was actually the first who recorded the presence of the 

 West Nile race of square-lipped rhinoceros" (Lang, 1923, p. 158) . 



According to Heller (1913, p. 34), "the first real evidence of its 

 occurrence to the north of the Zambesi River was the skull procured 

 in 1900 by Major Gibbons in the Lado Enclave." He seriously 

 questions "the earlier reports ... by Speke, Grant, Von Hohnel, 

 Gregory, and others. . . . There is little doubt but that all their 

 records referred to the black rhino." He continues (pp. 36-38) : 



The square-nosed rhinoceros is found at the present time in a wild state 

 only in the Lado Enclave and the Bahr-el-Ghazal province of equatorial 

 Africa. . . . 



In the Lado Enclave they are confined to the immediate vicinity of the 

 western bank. . . . Very little is yet known of their distribution westward. 

 The farthest point inland where they were met by Colonel Roosevelt was 

 . . . approximately 12 miles west of Rhino Camp. [This part of the former 

 Lado Enclave is now included in Uganda. 1 In this vicinity nine were seen 

 by Colonel Roosevelt in one day's journey .... A few days later Kermit 

 Roosevelt encountered 10 in the same general neighborhood. . . . The known 

 distribution of the white rhinoceros covers the two widely separated localities 

 of Lado Station and Rhino Camp, which are some 120 miles apart, and the 

 more distant Dar Fertit country. . . . 



There is little doubt but that the species is quite local in distribution, 

 and to this circumstance its long escape from discovery is to be attributed. 



"During Mr. A. L. Butler's direction of the Game Department of 

 the Sudan Government the white rhinoceros was placed on the 'Pro- 

 tected List' that is, the killing of it was absolutely prohibited. 

 But since his retirement in 1914 the poor remnant of rhinos that still 

 survive along the west bank of the Upper Nile have been replaced 

 on the 'Game List/ in respect of a paltry premium of 5. Unless 

 that wicked action is reversed it spells the death warrant of the few 

 white rhinos that remain on the Nile." (Chapman, 1922, p. 44.) 



"The case of the white rhino . . . is a pretty hopeless one. He 

 obviously belongs to another world, and his extinction in this is 

 fairly certain in the near future. In the British Sudan very few in- 

 dividuals remain. Those along the west bank of the Nile can, I 

 should fancy, not exceed half-a-dozen pairs. 



"A little farther westward, along the Nile-Congo Divide, from 

 about Yei in Western Mongala, to a point some distance north- 

 west of Tembura in the Bahr-el-Ghazal, they are more numerous, 

 especially in that section of the divide between Meridi and Yambio. 

 In that district in 1916 I came upon them many times in my 

 rambles." (Christy, 1923, p. 63.)
