256 CERCOCEBUS 



now considered to belong to various genera, as well as to 

 Lasiopyga. The species of Cercocebus are: 

 (C.) atys undeterminable; C. ^thiops (Schreber), and C. 

 fuliginosus Geoff., also = C. ^thiops (Schreber). 



1820. Desmarest, Mammalogie ou Description des Esp'eces de Mam- 

 miferes. 



Like the previous Author, the present one includes the species 

 of Cercocebus in Cercopithecus — (Lasiopyga), as follows: 

 (C) fuliginosus — C. ^thiops (Schreber) ; C. .ethiops 

 (Schreber) ; C. cethiopicus F. Cuv., = C. ^thiops (Schreb.) ; 

 and C. atys possibly an albinistic individual of C. ^thiops, but 

 undeterminable. 



1821. F. Cuvier, Histoire Naturelle des Mammifbres. 

 Cercocebus torquatus (Kerr), redescribed as Cercopithecus 

 athiopicus, the name however attributed to M. GeofFroy St. 

 Hilaire, but I have not found that either E. or L Geoffroy 

 employed this name for the species. 



1829. Fischer, Synopsis Mammalium. 



Two species of Cercocebus are here given as Simia ^thiops 

 Schreb. ; 5". fuliginosus = C. athiops (Schreb.). 

 The synonymy is badly mixed and incorrectly given. 



1838. /. E. Gray, in Proceedings of the Zoological Society of London. 

 Cercocebus albigena first described as Presbytis albigena. 



1840. Wagner, Schreber, Die Sdugthiere in Abbildungen nach der 

 Natur mit Beschreibungen. Supplementband. 

 In the genus Cercopithecus (Lasiof\ga), two species of Cer- 

 cocebus are included; C. fuliginosus Geoff., — C. .^thiops 

 (Schreb.), nee Simia athiops Linn., which is not a Cercocebus. 



1840. R. P. Lesson, Species Mammiferes Bimanes et Quadrumanes. 

 The members of the genus Cercocebus are included in the 

 genus Cercopithecus. They are (C.) cethiops = C. torquatus 

 (Kerr) ; and C. fuliginosus — C. .ethiops (Schreber). 



1851. /. Geoffroy St. Hilaire, Catalogue des Primates. 



Three species are here given. C. collaris = C. torquatus 

 (Kerr) ; C cethiops (nee Schreber), = C. torquatus (Kerr) ; 

 C. LUNULATUS Temm. ; and C. fuliginosus — C. ^thiops 

 (Schreber). 



1853. Temminck, Esquisses Zoologiques sur la Cote de Guinee.
