SYNOPSIS OF THE 
considered as merely varying from sex or age. The whole side of 
the head, which in the last species presents the well-defined black 
marking whence the bird derives its name, is in the present species 
covered with a patch of the most brilliant king’s-yellow. The 
general size of the two species is nearly the same, but in C. lam- 
protis the bill is smaller, the orange of the head is of a more red- 
dish tinge, the eye is entirely surrounded by black, and the whole 
of the wing-feathers, including the primaries, are lined with green. 
The only specimen I have seen is in the British Museum. For 
an opportunity of examining and taking a description of it, I am 
much indebted to Mr. G. R. Gray. It was brought from Bolivia by 
Mr. Bridges.
