localitv situated further West (Koloka, between Likati and 

 Bima rivers), but it inight nevertheless be identical with the one 

 described above, but as Matschie's original description is so short, 

 it is impossible to express any opinion about this. He had only a 

 skin without skull at his disposition vvhen giving the name quoted. 



Colobus palliatus mawambicus Matschie. 



Mawambi (Christy), n°' 1838, 1839, 2116, 2232; Grauer (ex 

 Mus. Wien), n° 1 124. 



This subspecies is easily recognized on the absence ot white 

 frontal band (') and absence of anv white on the perineal région. 

 The long white hairs do not extend to the back of the upper arm. 



It appears to be an inhabitant of the great Ituri forest. 



Probablv it is substituted alreadv in the Kivu région bv a some- 

 what différent race which to some extent approaches the following. 

 This hypothèse is based on the tact that the Congo Muséum pos- 

 sesses a native skin (n° 794) collected by Pauwels in « région du 

 lac Rivu », which difïers from niawambiciis in having the mantle 

 of white hairs extending so far that it just for a few centimètres 

 encroaches upon the most proximal portion of the upper arm. In 

 addition to this there are also some few white hairs on the perineal 

 région. Thèse do not, however, form a stripe as in Weyiisi, but are 

 more broadly scattered. The first of thèse two characteristics is 

 also found in a spécimen from « région des Lacs » (probably north 

 of Tanganyika) collected bv Grauer. This latter has not, however, 

 any white perineal hairs. Both spécimens agrée therein that they 

 hardly hâve anything pure white on the tail. In the Kivu-specimen 

 only the distal quarter of the tail is speckled with mixed black 

 and greyish white hairs, the latter increasing in number towards 

 the tip. In Grauer's spécimen the speckling with greyish white 



(') LoRKNZ has recently {Ann. Nalurhist. Hofi/ius., Wien, Bd 31, 1917) united mawam- 

 bicus with Collûii! Lyd., but as none of the présent spécimens show any trace of white hairs 

 indicating a brow band, 1 prefer to retain the above name.
