DUIKERS AND SMALL ANTELOPES 531 



A red duiker obtained near Edoma Ravine was made the 

 basis for the description of another race, ignifer, by Thomas 

 In 1903. This specimen showed a smaller amount of black 

 on the crown than the closely allied race, nigrifrons, of 

 the Congo. It is distinguishable from harveyi by the dark 

 color of the legs, by larger body size, and the presence of 

 some rufous hair In the crown patch. Recently, specimens 

 from Nairobi have been described as a different race, 

 kenicSy by Lonnberg, who gives the color differences with 

 harveyi as the character of his race. Nairobi specimens 

 have been compared at the British Museum with the type 

 of ignifer and with other specimens from Ruwenzori, and 

 have been found quite identical in coloration. Two adult 

 female specimens from Nairobi are in the National Museum 

 which show considerable variation In the amount of black- 

 ness on the crown, nape, and breast. The type has the 

 color of the back bright bay or ochraceous-rufous, darken- 

 ing forward on the neck and shoulders to dull brownish. 

 The forehead Is mixed rufous and black. The crown and 

 occiput are bright-rufous, like the back; and the coronal tuft 

 is a deeper and more chestnut or vinaceous rufous. The lips 

 and chin are white. The ears are dark-brown on the back, 

 with white edges and inner surfaces. The throat Is rufous 

 and the belly is brown mesially, grading into rufous, laterally. 

 The Inner side of the forearms, the inguinal region, and the In- 

 ner side of the thighs are white. The outer side of the thighs 

 and the forearms is rufous. The feet are brown, darkening al- 

 most to black above the hoofs. The tail Is rufous above, white 

 belowproximally, with a mixed brown and white terminal tuft. 



The skull length of an adult male Is 6>^ Inches, that of 

 a female 6^ Inches. The horn length of a male from 

 Eldoma Ravine is 3^ inches with a basal diameter of 1% 

 inches. The horns of an adult female from Nairobi are 

 about one-half of these dimensions. They are ij/i Inches 

 in length by ^ of an Inch in diameter at the base.
