CERCAERTUS—CERCOPITHECUS. 13 
Cercaértus—Continued. 
Type: Phalangista vulpira Desmarest (= Didelphis vulpecula Kerr), from Australia. 
Name antedated by Trichosurus Lesson, 1828. 
Thomas dismisses Cercaértus with the remark: ‘‘said to be founded on Trichosurus 
vulpecula, but obviously a misspelt form of Gloger's Cercartetus." Thomas 
gives the type of Cercartetus as Didelphis peregrinus Boddaert, but the only 
species mentioned in the original description of the genus is Phalangista nana. 
Cercaértus: Képkos, tail; &eor«c, to lift up.

Brünnich based his genus on the ‘ Marekatten.’ 
Erxleben in 1777, included 22 species: Cercopithecus hamadryas Erxleben, from 
Arabia and northeast Africa; Simia veter Linnzeus, from southern India; Cer- 
copithecus senex. Erxleben, from Ceylon; C. vetulus Erxleben, from Ceylon;

*Sherborn (Index Animalium, 1902), refers Cercopithecus to ‘‘Gronovius, Zooph., 
I, 5, 1763." 
T Brisson divides Simia into five stirpes, two of which are not valid subgenerie 
names, e. g., Simia cynocephala and Cercopithecus cynocephalus, hence all are discarded.
