ERYTHROCEBUS 17 



Reichenbach (1. c.) has given a figure of a red Cercopithecus, 

 (Erythrocebus), with a white brow band and white whiskers sur- 

 rounding the face, which he named circumcinctus. I have not seen 

 any example of this genus which resembles this animal. It is not 

 known where Reichenbach's type was obtained, and it is not now in 

 the Dresden Museum, and may never have been there, for it is well 

 known that Reichenbach included many species in his book which were 

 not in the Dresden Collection, but which he obtained by loan from 

 various persons and Institutions ; and some possibly he never saw at 

 all, but copied the figures from the published works of various authors. 

 His description of Cercopithecus (nee Gronov.), circumcinctus is as 

 follows : C. circumcinctus Reich. "Patas mit scharzen, weiss ein- 

 gerahmten Gesicht, Rothelfarbig Stirnband und Umgebungen das 

 schwarze Gesicht und Kinn, sowie die Unterseite und Innenseite der 

 Gliedmassen weiss. Befand sich im J. 1830 hier lebendig und wurde 

 von unserm Thiermaler Herrn W. Wegener, skizziet und mir gefallig 

 mitgetheilt. Die angefiihrten Kennzeichen unterschieden ihn sehr 

 bestimmt von seinen Nachbarn Wahrscheinlich aus dem westlichen 

 Afrika."
