HECK'S DUIKER 165 



shoulders, flanks, and thighs are dull deep rufous, the under-parts 

 greyish rufous, and the limbs, with the exception of between the main 

 and lateral hoofs (where they are brown), bright rich rufous. The 

 rump is dark chocolate -brown, and the under side of the tail still 

 darker blackish brown ; the forehead is, as usual, dark, with rufous 

 brow-streaks, and the outer sides of the ears are brown, with a small 

 rufous patch near the front of the base. A few white patches occur on 

 the under surface between the two fore and the two hind legs. 

 The type specimens were obtained at Mlanjc, Nyasaland. 



HECK'S DUIKER 



( CepJialophus Jiecki) 



This duiker, which inhabits Mozambique, and was named in the 

 Sitzungs-Berichte Ges. Naturfor. Berlin, 1897, p. 158, by Dr. P. 

 Matschie, is distinguished from CepJialopJnis nyasce by having more, 

 instead of less, white on the under-parts, as compared with C. monticola ; 

 by being apparently less rufous on the body, and by lacking the usual 

 dark markings on the back of the pasterns. The lateral hoofs are 

 also smaller than in monticola or nyascs. The legs are red, as in 

 monticola. 



THE URORI DUIKER 



{CephalopJnis liigens) 



A member of the blue duiker group, but of larger size than 

 CephalopJnis monticola, C. melanor/ieus, or C. cequatorialis, and also darker 

 in colour ; its legs being brown, and thus different from those of monti- 

 cola and hecki, which are red. The species is a native of Urori, British 

 East Africa, and was described by Mr. O. Thomas in the Zoological 

 Society's Proceedings for 1898, p. 393. 



On the upper-parts the general colour is dark umber-brown, with the 

 forehead and top of the muzzle nearly black, the unusually long crest 

 black, the sides of the face brown, relieved by a whitish line above the 

 eye, and the outer surfaces of the ears black in their front half Neck 

 brown, like the back, with the hairs on the nape reversed so as to 

 incline forwards. Back darkening almost to black on the loins, but 

 this darker area not relieved by a lighter patch on the outer side of 

 the hip, as in melanor/ieus and csguatorialis, and the hips uniformly
