but it is still one of the rarest. There is a specimen in the British Museum, and another 
in the Derby Museum at Liverpool ; and besides these two we are not aware of any other 
in England. Our Plate and description were taken from the former one, and represent 
an adult male. The female is still unknown, but probably closely resembles that of C. 
(jlaucogularis, a figure of which is given. 
C. versicolor differs from its commoner congener C. iourcieri chiefly in its broad blue 
moustachial stripes meeting under the chin. C. glaucogularis has these moustaches yellow. 
It has been figured both by Buffon and Le Vaillant, but in none of the works of 
modern authors.
