Simla CAPUcix.A. Linnseus has been generally recognized by 

 Authors as the monkey with the sides of face, throat, chest and front 

 part of the shoulders grayish yellow, or grizzled, (gray and black). In 

 the Museum Regis Adolphi Frederici, 1754, the work in which Linnaeus 

 first employed the binominal system, two species of Cebus are figured 

 and described as Simia apella and Siniia capucina. The plates are 

 recognizable, that on which the latter species is portrayed eminently 

 so, and represent the forms recognized by Authors generally as Cebus 

 capucinus and Cebus hypoleucus, and the descriptions given, 

 fairly, if not completely, describe the figures, and the one known to 

 Mammalogists at the present day as Cebus hypoleucus is called S. 

 capucina, and the other 5". apella, and these names must take 

 precedence for these forms. In the 10th edition of the Systema 

 Naturae, 1758, p. 29, Linnasus gives a brief description of 5". capucina, 

 not sufficient however to cause the form to be recognizable, but the 

 only authority he gives is his own work the Mus Reg. Ad. Fred., 

 which thus fixes the animal, (afterwards named by Humboldt hypo- 

 leucus), as his 5. capucina. In the 12th edition of the Systema 

 Naturae, 1766, p. 43, the one cited by many European Naturalists, 

 under S. capucina, Linnaeus gives quite a different description of this 

 monkey from that in the !vlus. Reg. Ad. Fred., and instead of "pallida 

 flava est una cum pectore ad flexuram usque cubitorum" as exhibited 

 in the figure of his plate, he writes "pectus ferrugineum," which 

 describes neither capucinus nor hypoleucus of Authors. It is on
