This work is a monographic essay on the genus Colobus, and 

 is divided into two groups. "A. Formse pilis brevibus vel 

 subelongatis ; vellere versicolore attamen prascipue rufo, cas- 

 taneo, olivaceoque permixto" includes the following genera: 

 Procolobus for C. verus ; Tropicolobus for C. rufomitratus ; 

 PUiocolobus for C. ferrugineus; C. bouvieri first described; 

 C. THOLLONI ; and C. kirki ; Stachycolobus for C. satanas ; 

 Colobus for C. ursinus = C. polycomus; and C. angolensis; 

 Pterycolobus for C. vellerosus ; Guereza with C. riippellii = 

 C. ABYSSINICUS ; C. caudatus ; and C. occidentalis first de-

 here C. polycomus ( !) and gives a list of synonyms which he 

 afterwards discusses at length. Very fair colored figures of

 not necessary but may serve as subgenera, indicating artificial 

 groups for the division of the species.
