10 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6l 



Measurements. — Length of fresh skin, 525 mm. ; tail, 85 ; hindfoot, 

 170; ear from notch, 55. Skull: condylo-basal length, 112; zygo- 

 matic breadth, 55; upper tooth row, 32; PM 1 to muzzle, 39; nasals, 

 39 x 22 ; orbit to muzzle, 68 ; diameter of orbit, 24 ; length of pre- 

 maxillae, 34; condylo-incisive length of mandible, 92; diastema, 28. 



Remarks. — Seven skins and three skulls are in the collection from 

 the Kakumega Forest. They agree in differing from Uganda skins 

 of aeguatorialis by their lighter underparts and larger size. These 

 specimens represent a highland race of the widespread blue duiker, 

 which extends across Africa from the west coast as far as the Nandi 

 Forest lying on the western slope of the Mau Escarpment, in British 

 East Africa. Although living relatively close to .the Uganda blue 

 duiker the present race inhabits a forest 2,000 feet or more higher 

 and much colder.

 rower or obsolete ; pelage shorter and thinner ; length on back 20 mm., 

 in R. zvardi, averaging 30 mm. 



Coloration. — Color of upper parts tawny, purest on sides and legs ; 

 dorsal region darkest owing to prevalence of black tipped hairs which

 patch between ears ; midline of snout speckled by dusky ; sides of head 

 pure yellow-ochre, orbital area lighter buff in color; chin and upper 

 throat cream ; back of ears much darker than body ; general effect 

 snuff-brown, the hair covering however tawny ; inner side and base

 brown stripe in front from hoofs to shoulders on forelegs, but only 

 reaching halfway to hocks on hindlegs. Tail tawny above, white 

 below, the tip chiefly white. Underparts pure white sharply defined 

 on sides against the tawny-ochraceous, the white reaching as far for- 

 ward as the chest and extending as a narrow line down the inside 

 of the legs.
