mantes Thierchen : da es aber keine Milcb triuken wollte — 

 ich halte zu solchen Zwecken stets etwas condeusirte Milch 

 vorrathig — und Tag uud Nacht ohne Auf horen schrie , 

 verurtheilten wir es »to the end of a rope". 



Description of the young specimen : 



Crown of head , nape of neck and back silverly white , 

 passing into livid on the upperarras and thighs , mean- 

 while the hands and the legs are black for the rest. Head , 

 sides of body and underparts white, with numerous black 

 ' hairs interspersed. Tail with a well developed tuft ; the 

 tail is black towards its basal end , the hairs of the tuft 

 are white with a black tip on each hair, so that the ex- 

 treme end of the tail where the black tipped hairs come 

 together is black. All the hairs of the upperparts of the 

 body are undulated , like in the young Colobus guereza 

 mentioned by Schlegel (Simiae , p. 25 and 26). 



Length of head and body 330 mM. 

 » » tail with tuft 348 mM. 



Professor Schlegel thought it to be a young Colobus po- 

 lycomos llliger and under that name it is to find in my 

 Catalogue osteologique , p. 6, but until we possess young 

 specimens of all the known Co/oius-species to compare 

 with I believe it better to mention it with a?, and in so 

 doing to avoid confusion. 



Very important is the peculiar color of the tail : the 

 tuft has a tendency to grow black , so that it is not too 

 hazardous , I think , to suppose that in adult specimens 

 the tuft will be black throughout. Up to this time however 

 we do not know a Co/o6?/s-species with a black tufted tail, 

 the single species with a black tail is Colobus satanas^\>ni 

 in this species the tail has no tuft. As there is no reason 

 moreover to accept that untufted specimens of a given spe- 

 cies were tufted in their youth , it could be that our 

 young specimen belongs to an unknown species, perhaps 

 to a species, which we must ascribe a black tail with a 

 black tuft.
