Saimiris lunulatus, Is. Geoff. Ann. du Mus. iv. p. 18, with 
a black lunule over each eye. Can this be a bad descrip- 
tion for S. entomophagus ?

The figure given by Spix is very badly coloured, but the description 
agrees well with the specimens. Geoffroy’s figure is from a specimen 
with the end of the tail white ; his figure is as much brighter than the 
Museum specimen as Spix’s is too sombre. 
b. The hands white ; the feet black ; tatl black.

Black, reddish-washed ; hairs black at the base ; chest with a pure- 
white spot; hands white; feet black ; forehead and tail black ; hairs
