104 TETRAONIDE. 



The upper part of the back arid sides of the neck, red brown. 

 Back, wing-coverts, and tertials, burnt sienna, pencilled all 

 over with black ; rump and upper tail-coverts, olivaceous 

 brown and sienna, and also pencilled with black. Most of 

 the feathers on the upper parts of this bird are edged 

 with blueish ash-colour and straw yellow ; the under parts 

 are white and yellowish white ; the feathers of the breast and 

 belly, edged with black. The side and flank feathers are 

 beautifully marked in the centre by rich chestnut brown, 

 bordered with black and white ; tail-feathers are blueish ash- 

 coloured. 



The female differs chiefly in the head being of a uni- 

 form wood-brown, with dusky edges to the feathers on the 

 top of the head ; the feathers of the other parts are less 

 distinctly marked, and the colouring is less brilliant. 



The egg figured 156 is that of the Virginian Par- 

 tridge.
