TRAGELAPHIN^E 169 



Typical locality Kalakaba, about 40 miles from Mahagi, 

 at the north end of the Albert Nyanza, below the water- 

 shed of the Ituri. The typical locality of d. simplex is the 

 Ituri Valley, near Kifuku and Irumu ; and that of d. sassce 

 Kasindi, north of the Albert Edward Nyanza, where simplex 

 is also stated to occur. 



Type in the collection of Major Powell-Cotton at Quex. 



Typically a large, short-haired, and long-tailed race, in 

 which the total length of the skin is fully 63 inches (160 cm.), 

 and that of the tail llf to 13 inches (29-33 cm.). Neck 

 with a short-haired collar ; dorsal crest blackish brown with 

 a few white hairs, but in immature males largely mingled 

 in its hind portion with white and ochery brown hairs; 

 general colour orange-ochre, with a rufous tinge in females 

 and young males ; middle line of under-parts black, but 

 orange-ochre in females ; markings variable, being in some 

 cases indicated only by a few transverse lines of longer 

 hairs, but in others by from four to nine transverse stripes, 

 of which some show white spots, and a longitudinal line of 

 flecks, with a few spots on upper part of thigh. The so- 

 called d. simplex is stated to differ by its smaller size and 

 paler colouring, the general tint being more ochery and less 

 inclined to rufous ; d. sassce is intermediate in size between 

 the two others, very similar in colour to the first, but greyer, 

 with a distinct longitudinal line of white flecks, which tend 

 to unite posteriorly into a band, four or five more or less 

 distinct transverse white stripes, five large spots on haunches, 

 and the posterior half of the dorsal crest nearly white.
