C. castaneiis oricntalis proves, that race as well may be very dark 

 in some instances. Therefore I do not think now that the two 

 races can be distinguished on colour différences, as I believed at 

 first, when I had onlv little material. 



Cephalophus rufilatus rubidior Thomas and Wroughton. 



Two spécimens trom the Bafuka forest, N. of Niangara (1280 

 and 1281). 



Both thèse spécimens are young and, as it seems, somewhat 

 lighter, at least below, than the type. To express the small size of 

 this species the following comparison may serve. In both cases the 

 skulls measured belong to \ oung animais with milk-molars, first 

 molar, and second molar just appearing.

Total length ofskull . . . 144 mm. 169.7 mm. 



Basai length of skull . . 124 » 152-3 » 



Zygomatic width 65.3 » 71.5 »

The somewhat older maie ot C. rufilatiis rubidior has ;//" fully 

 developed and m^ just appearing. The total length of its skull is 

 147.2 mm., basai length 130 mm., zygomatic width 69 mm., preor- 

 bital length 71.3 mm., length of nasals 148.2 mm. The horns hâve 

 alreadv a length of 70 mm. and a basai diameter of 25 mm. It is 

 thus comparatively well armed. 



This subspecies was originally described from the Uele valley, 

 and it does not appear to extend further south. 



Cephalophus Simpsoni Thomas. 



Two maie spécimens (2349 and 2350) coUected by Pilette at 

 Kindu. 



The t\pe of this interesting little Duiker was found at Kole in
