Type of Grimmia. 



Typical locality Gambia. 



The smallest of the red duikers (agreeing approximately 

 with the blue C. natalensis), representing a dwarf type of the 

 dorsalix group with the black areas replaced by grey, and 

 the rufous, or chestnut, typically of a lighter tint than 

 usual. Height at withers about 14 inches ; horns very 

 small ; direction of hairs on nape normal. General colour 

 bright yellowish rufous or ochery buff on sides of face, neck, 

 shoulders, flanks, rump, and under-parts, bluish grey on 

 middle line of nose, forehead, back of head and ears, middle 

 line of back from withers -to rump, and lower part of limbs ; 

 crest long, blackish ; tail rufous above at base, black at tip. 



Skull with long and slender muzzle and deep lachrymal 

 pits ; central palatine notch about J inch in advance of 

 lateral ones ; basal length 5, maximum width 2f , interval 

 from orbit to muzzle 2J inches. Length of ear 2, of hind- 

 foot 7 inches. 



The slate-coloured legs and dorsal stripe, together with 

 the thicker horns, serve to distinguish this species from the 

 much larger C. harveyi and C. nigrifrons. 



This range extends along the west coast of Africa, from 

 Gambia to the Niger. 



The two local races are distinguished as follows : 



a. General colour yellowish rufous or ochery buff; 



nape, dorsal patch, and feet smoky grey C. r. rufilatus. 



b. General colour burnt-sienna ; nape, dorsal patch, 



and feet slaty grey C. r. rubidior. 



A. Cephalophus rufilatus rufilatus. 



Typical locality Gambia.
