 Two species only are here recorded, C. niger, and C. nigrescens

 One species is given in this list, Cynopithecus nicer ; and C. 

 nigrescens Temm., is considered as a "browner or grayer" 

 variety. 



1876. Schlegel, Museum d'Hlstolre Naturelle des Pays-Bas. Slmice. 

 In this work but one species of Cynopithecus is recognized, 

 C. NIGER Desmarest. The Author remarks upon the variation 

 in color of examples dwelling at different places in northern 

 Celebes, and in the Island of Batchian, also on the different 

 shape of the callosities. He, however, regards these as merely 

 individual variations, and decides that the two forms, nicer 

 and nigrescens, the only ones known to him, represent but 

 one and the same species ; and in the more than thirty years 

 that have elapsed since his work appeared, sufficient additional 

 knowledge of these Apes has not been acquired to enable us to 

 prove that Schlegel was not quite correct in the decision he 

 gave. 



1901. P. Matschle, in Senckenbergische Naturforschende Gesell- 

 schaft. 



In his paper on the mammals of Halmahera, Batchian and 

 North Celebes, the Author reviews the species of the genus 

 Cynopithecus, but placed in Papio, and criticizes to some 

 extent, the papers of A. B. Meyer previously published on the 

 same animals. He first discusses the relationship of Cyno- 

 pithecus and Macacus, and allied genera, and the species 

 properly belonging to each, and their geographical distribution. 

 As our present investigation is mainly with the species of
