coverts the same, bordered with maroon ; tail, upper surface green, lower aspect blue. 

 A large crimson patch below the blue of the throat, not clearly defined but encroach- 

 ing on the breast ; remainder of lower surface bright yellowish grass-green— far more 

 tinged with yellow and of a much brighter tint than are the same parts in C. asiutica — 

 much smeared and splashed with brilliant scarlet crimson, particularly so on the 

 breast and under tail-coverts. Bill greenish yellow, base of maxilla aud basal half of 

 culmen almost black ; gonys darker green ; irides dark brown ; orbital skin dull 

 orange ; legs dull dirty green, claws almost black. 



Length alx)ut 8."5 ; wing 3."75 — 3."85 ; tail 2. "5 ; bill from gape l."24. In addi- 

 tion to the difterences in coloration, this bird seems to be decidedly .smaller than 

 C. asiatica, with a proportionately longer bill. 



I give comparative measurements of my proposed 0. riibescens and four G. asiaiica 

 taken from the same district : — 



This species seems to be confined to the very highest ranges in the east of 

 the Cachar hills, not descending below 3500 feet, below which it is replaced by 

 C. asiatica. 



In the Asian I mentioned the fact that I liad obtained .specimens intemiediate 

 between C. asiatica and C. nibescens, but further investigation has shown me that 

 such are merely young birds of the latter species, and I have no fully adult birds 

 which are not easily assignable to the one or the other. Moreover the habitat of the 

 species is different. C. asiatica does not ascend above 4000 feet, and is not often 

 found much over 3000 ; whereas G. rubescens is a bird of lofty elevation, seldom 

 occurring below 4000, and never, I believe, below 3500 feet. 



]?lanford (Fauna of B. I. Binh, Vol. III.) says : " Males from the Cachar hills 

 are said to have the mantle-feathers and upper tail-coverts tipped with maroon, and 

 the under tail-coverts splashed with vermilion." I wrote to him about this, and in 

 the answer which he kindly sent to me he says that his remark was made on the 

 strength of what I wrote in my article in the Asian above referred to. 



The type-specimen of this species is now in (he lion. \V. Rothschild's Jluseum 

 at Tring.
