OF NORTH-EASTERN CACHAR. 243 



feathers 2 inches, and side feathers 1^ inches wide, tipped witli 

 white ; chest dark cinnamon ; breast or body cinnamon, though 

 slightly lighter than chest, most feathers having a heart-shaped 

 black spot ; vent whitish, tinged with creamy ; under tail- 

 coverts almost white ; under wing pure white, with a few 

 black oblong spotS ( on secondary and tertiary under wing- 

 coverts ; feet yellowish orange ; claws pale whitish yellow ; 

 thigh-coverts light cinnamon ; cere darker yellow than legs ; 

 bill bluish horny at point, somewhat lighter at base. — J. I" 



A very fine perfectly adult male of this species, procured 

 near Dilkhushah, is clearly pekinensis, with the entire wing- 

 coverts blue, except a few just where the wings join the body. 



The wing is only 9*2 ; tarsus only 1*1. My C. inglisi, with 

 nearly the whole of the wing-coverts red, is a less mature bird 

 of this present species. 



In the present adult male specimen the entire breast and 

 upper abdomen are spotless, and there are only a few small 

 oval brown spots on the lower abdomen ; the entire chestnut 

 of the back is uniform and unspotted, only the one longest 

 scapular on each side is broadly blue grey at the tip, and the 

 next longest scapular has a small blue, oval, subterminal spot, 

 and the next has the shaft just perceptibly darker than the rest 

 of the feather; the wing-lining is pure unspotted white. 

 This is the most mature specimen I have ever seen, but pos- 

 sibly in the very old bird all marks above and below disappear.
