THE CALIFORNIAN ORTYX.

is a crescent band of pure white. The feathers of 
the lower part of the belly are deeply margined with 
black, and the long plumes of the flanks are marked 
along the centre with a stripe of yellow. But the 
beautiful and remarkable adornment is the crest up- 
on the crown, composed of several feathers, narrow 
at the base broadening towards the tip, and folded 
as it were together from the shaft. They are of a 
dull rich black and lie generally backwards, but can 
be raised at pleasure ; and upon any excitement are 
erected, almost bending forward upon the front.
