CEBUS 67 



error that had been committed, but had. not the courage to 

 correct it. A third species C. fatuellus is also here first 

 described. 5. trepidus is undeterminable. All are placed in 

 Simia.

The following species of Cebus are recorded: C. fatuellus, 

 C. CAPUCiNus and C. apella, of which the Author remarks 

 "Hie quibus differat a capucino, non satis intelligo." 

 So early had the confusion between these totally distinct species 

 commenced. C. trepidus is undeterminable as "manibus pedi- 

 busque caeruleis" is found in no Cebus known. Other species 

 are given under Cebus but do not belong to the genus. 



1788. Gmelin, Systema Naturce. 



C. CAPUCINUS is given with Linnaeus' original description, and 

 his, the only work cited ; the synonymy, however, is mixed. C. 

 apella with the original description ; and C. Fj\tuellus. All 

 these are placed in the genus Simia.

Cebus capucinus renamed Simia (Sapajus) capucimis albulus. 



1797. /. B. Audebert, Histoire Naturelle des Singes et des Makis. 



Three species and three varieties, with figures of all are given 

 in this work under Simia: (S.) fatuellus; (S.) apella; var. 

 A. a dark individual of the same species which died in the 

 Menagerie of the Paris Zoological Garden. (S.) capucinus, 

 var. A. represents the typical style; but (S.) capucinus, with 

 red on forearms, and var. B. with a red breast, are unlike any 

 example of C. capucinus I have ever seen, and it is impossible 

 to determine what species they represent.

In his subdivision Cebus six species are recognized. Cebus 

 albifrons first described; and (Simia) capucinus Linn., 

 redescribed as Simia hypoleucus; C. apella (Linn.), called 

 (5".) capucina (nee Linn.) ; (S.) cirrifer first described, and 

 (S.) variegatus E. Geoffroy, but not described by that Author 

 in 1811.

 Naturelle, Paris. 



In his Tableau des Quadrumanes, this Author gives the follow- 

 ing species of Cebus: C. apella (nee Linn.), = C. fatuellus; 

 C. cirrifer ; C. barbatus = C. flavus ; C. trepidus undetermin-
