dimension of the above mentioned spécimen from Baraka is 

 22.2 mm. The diameters of w/^ are in the former 5.5X5.3 and in 

 the latter 7.2x6.4 mm. This proves that the /eucainpyx-moïùity 

 from Kutu must be a considerably smaller animal than its relatives 

 in other districts. The above mentioned exterior différences can 

 also hardly ail be juvénile, when the animal has been old enough 

 to develop its ;«'. It appears thus to form a separate géographie 

 race, which I take the liberty of naming for the collecter Cer-= 

 copithecus leucampyx Maesi. 



Cercopithecus leucampyx elgonis n. subsp. 



3 ad. spécimens from Elgon, collected by Dr. Bayer. 



Thèse three spécimens resemble (\ leucampyx Carruthersi, but 

 differ from the same at the first look bv their verv strona:lv develo- 

 ped wooUy underfur, and by being darker. The black from the 

 head extends down on the interscapular area, but is there some- 

 vvhat ticked with whitish rings to the hairs. Arms and hands are 

 qnite black. The back similar to that of Carruthersi, but it is in 

 one of the spécimens (the type) decidedly more black. The hind 

 legs are (unlike in Carruthersi) black, scantily ticked with narrow 

 vvhite rings on the thighs, without markings on the lower parts and 

 feet. The tail, on the other hand, is more speckled than in Carru- 

 tlicrsi the hairs being banded with white nearlv over the whole 

 organ, so that only the extrême tip is pure black. Throat greyish 

 white or light grey. The lower parts of the bodv are sootv blackish 

 with the rich grev wool shining through. There are no traces of 

 fawn coloured or rufous hairs below the root of the tail, or in the 

 anal région. 



The skull of an adult female appears to be similar to that of a 

 corresponding spécimen of Carruthersi from Rutshuru.
