edge, along the inner webs. The tail is pale red, 

 tinged with grey, and has about ten narrow bars of 

 blackish-brown, the extreme bar nearly an inch in 

 breadth, and the tip reddish-white. The lower parts 

 are pale yellowish-red, longitudinally streaked with 

 dark brown on the fore-neck and breast, the streaks 

 guttiform on the latter, and on the sides forming trans- 

 verse bands. The outer tibial feathers have small 

 elongated dark markings ; the abdominal feathers and 

 lower tail-coverts unspotted, as in the male ; the lower 

 wing-coverts white, with oblong brown spots. The 

 bill and other bare parts as in the male.

Variations. — The males vary a little in size and 

 colour. Younger individuals have the grey on the 

 head less pure, the secondary quills marked on the 

 outer webs with spots, and on the inner with bars of 

 red, and the inner webs of the tail-feathers with eight 

 bars of deep brown. The females also diflFer in size 

 and colour, as^suming more grey on the head and tail 

 the older they grow. The plumage, when fresh, is 

 brighter and more deeply tinted, and becomes paler 

 and bleached towards the period of renewal, but no 

 very remarkable changes take place. 



I have observed a difference in the coecal appendages 

 of the intestine, which it is of some importance to note.
