 Four species are here given. P. chrysocephala ; P. monacha, 

 with P. irrorata Gray, as a synonym ; P. ruHventer — P. pithe- 

 cia, with P. pogonias Gray, as a synonym ; and P. albicans 

 described for the first time. Two others are mentioned as ap- 

 parently distinct, P. leucocephala Geoff., = P. fithecia ; and P. 

 ALBiNASA. These had not been seen by this Author. 



1862. Reichenbach, Die Vollstdndigste Naturgeschichte der Affen. 

 In this work the species of Pithecia are divided between that 

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

 P. CAPiLLiMENTOSA ; P. CHRYSOCEPHALUS ; (Y.) leucocephola 

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

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

 B. israelita Gray = P. chiropotes as does also C. sagulata 

 Gray.

 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. ruHventer = 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 Onakaria has three species, 

 all of which are now included in the genus Cacajao. 



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

 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. Simia pithecia 

 Linn., is given among t^e 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 Pelaeln, Brasilische Saugethiere, Resultate von Johann 

 Natterer's Reisen in der Jahren 1817 bis 1835. 

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

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

 P. hirsuta = P. monacha ; P. chiropotes ; and P. satanas.
