The EAST AFRICAN ELAND (T. o. patter sonianus Lydekker 1 ) ranges 

 from southern Anglo-Egyptian Sudan (east of the Nile) through 

 Uganda, Kenya, and Tanganyika Territory, and west to Ruanda. 

 Although it has suffered from hunting and from rinderpest, and is 

 local in its distribution, it remains in moderate numbers over much 

 of its range, and has even shown an encouraging increase in pro- 

 tected areas.

 trict of Tanganyika Territory, does not seem to be clearly differen- 

 tiated from T. o. patter sonianus.}

The typical Derby Eland is now considered rare everywhere in 

 its West African range. 



General color deep chestnut or rufous; 14 or 15 narrow white 

 transverse stripes on sides; neck black, with a brown mane, and 

 bordered posteriorly with a white collar ; adult bulls with a chocolate 

 frontal tuft; nose black; sides of head dusky brown; an oblique 

 whitish stripe in front of each eye; lips and chin white; ears large, 

 marked with white, black, and brownish; a broad median black 

 dorsal stripe from neck to tail; under parts nearly white, middle of 

 belly black; a black patch on back of foreleg above the knee; 

 pasterns black behind. Height at shoulder probably about 70 inches. 

 Horns large, massive, divergent, twisted. Females smaller, with 

 smaller horns, and without frontal tuft. (Sclater and Thomas, 1900, 

 vol. 4, pp. 215-216.) Record length of horns, 36i inches (Ward, 

 1935, p. 246) . 



This Eland occurs in the interior parts of Senegal (Bofing), 

 Gambia, French Guinea (Fouta Djallen), and the Ivory Coast, 

 and along the upper Niger (Tinkisso) (General Government of 

 French West Africa, in litt., November, 1936) . Portuguese Guinea 

 is also included in its range (Ward, 1935, p. 246) . 



Reade writes (1863, pp. 169-170) that when he was on the Casa- 

 mance, in Senegal, he was told that the animal was most abundant
