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. 1 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 (nec Gronov.), CIRCUMCINCTUS is as 
follows: C. circumcincitus 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 angefihrten Kennzeichen unterschieden ihn sehr 
bestimmt von seinen Nachbarn Wahrscheinlich aus dem westlichen 
Afrika.”
