6 ZOOLOGICAL RESEARCHES 



3. Colohus ursinus, Ögilby. 



Soforé-place (Büttikofer and Sala) ; Robertsport (Büttiko- 

 fer and Sala) ; Grand Cape Mount (Büttikofer) ; Junk 

 River (Stampfii); Du Qneah River (Büttikofer and Stampfli). 



Iris light brown. 



Dieser Affe ist viel seltener als Colobus ferrugineus. Ihr 

 Geruch ist so stark , dass man schon daran ihre Nahe er- 

 kennen kann , denuoch ist ihr Fleisch schmackhafter als 

 das der meisten Cercopithecus-Kri&n. Wird meist allein , nie 

 in grössern Trupps angetroffen; höchstens in 8 Exemplare 

 beisammen. 



According to Büttikofer's informations is Since the most 

 eastern locality where the natives bring skins of this spe- 

 cies from the interior. 



The young specimens of this species are white colored , 

 with here and there interspersed black hairs 5 they have 

 a very well developed tuft on the tail. They very soon 

 become dressed like the adult ones. 



One of our skeletons presents 7 cervicales , 12 costales, 

 7 lumbares, 3 sacrales and 29 caudales , another skeleton 

 7 cervicales, 12 costales, 8 lumbares, 3 sacrales and 28 

 caudales. They are both females and of about the same 

 age. As the number of 7 lumbares seems to be very con- 

 stant in the Colohus- gvoxx^ (except in Colohus verus) I think 

 we must suppose that the skeleton with 8 lumbares is an 

 abnormity , the more as we know not another example of 

 a true Monkey with more than 7 lumbares. In the Lemu- 

 rina the number of lumbares varies from 6 to 9.
