 genus and Yarkea as follows: P. rufiventer = P. pithecia; 

 P. capillimentosa ; P. chrysocephalus ; (F.) leucocephala 

 = P. pithecia; (Y.) ochrocephala = P. chrysocephala; 

 (Y.) inusta = P. pithecia; and (F.) irrorata = P. pithecia;

 Bats, in British Museum. 



The species of Pithecia are here divided into two Tribes, 

 Pithecina and Brachyurina. The first contains the genus Pithe- 

 cia with four species, viz.: P. albicans; P. rufiventer = P. 

 pithecia; P. leucocephala = P. pithecia; and P. monacha. 

 Brachyurina has two genera Chiropotes, with (C.) satanas; 

 (C.) sagulata = P. chiropotes; (C.) ater = P. satanas; and 

 (C) albinasa. The second genus Ouakaria has three species, 

 all of which are now included in the genus Cacajao. 



1876. Schlegel, Museum d'Histoire Naturelle des Pays-Bos, Simla. 

 In this work nine species are placed in the genus Pithecia, 

 viz., P. nocturna = P. chrysocephala Geoff., which is con- 

 sidered a variation from the typical style. Simla pithecia 

 Linn., is given among the synonyms, but, although it has a 

 prior claim, is not adopted as the name of the species. P. mona- 

 cha; P. albinasa; P. chiropotes; P. satanas; P. melano- 

 cephala, P. calva, P. rubicunda and P. alba, the last four not 

 belonging to Pithecia, but now contained in the genus Caca- 

 jao, but P. alba is a supposititious species no example having 

 ever been procured. 



1883. A. von Pelzeln, Brasilische S'dugethiere, Resultate von Johann 

 batterer's Reisen in der Jahren 1817 bis 1835. 

 Five species of Pithecia are here recorded as follows : P. leu- 

 cocephala Audeb., = P. pithecia Linn.; P. chrysocephala;
