grow to still larger size. The C. L'hoesti Thomasi from Kivu is 

 about i6o cm. with similar proportions betvveen tail and body. 



When, however, Ei.i.iOT refers « Thomasi » to the alhigularis 

 group, I think he is more correct. It appears to me, that C. L'hoesti 

 might be regarded as a member of the alhigularis séries with rich 

 coloiirs, as thev develop in the aequatorial forest, and an excessive 

 growth of the vvhiskers. The form Thomasi appears to hâve, as 

 far as is known hitherto, a somewhat more southern distribution 

 than the tvpical L'hoesti. 



Further material mav, however, décide whether they might be 

 kept apart or not.

The spécimens in this collection, which are from varions places 

 in the district of Lake Leopold H and further one from Kasai and 

 a mounted one from Stanleyville, are quite typical in every respect. 



Two spécimens from the Uelle districts, viz. one (n"982)from the 

 neighbourhood of Zobia, and another (n" 1287) from Bafuka north 

 of Niangara differ from the others, but are similar inter se. Both 

 are apparently fully adult maies. They hâve the ochraceous semi- 

 lunar, frontal band perhaps a little better bordered with black in 

 front, at the same time as it is decidedlv paler than in typical 

 spécimens and in its posterior part whitish in conséquence of the 

 long white tips to the hairs. The posterior black band is strongly 

 developed. 



It might be possible that this signifies a separate geographical 

 race from Uele, but as the knowledge about the variation of thèse 

 monkeys is insufficient, I think it is best to wait for more material, 

 before the question is decided.
