the Indian authors, but only a somewhat pale variety of P. tristis. Compared with my series 

 of this latter species it differs merely in being somewhat paler in colour, but clearly shows the 

 sulphur-yellow on the carpus and the axillary plumes. This specimen is undoubtedly referable 

 to the pale form of P. tristis mentioned by Brooks, who writes (Stray Feathers, viii. p. 477) as 

 follows: — "The longer, broader, and less pointed first, or bastard, primary is a good mark by 

 which to distinguish P. sindianus from a pale tristis. Sometimes tristis is pale altogether, and 

 as slightly yellow and green as sindianus, and then attention to the size and shape of this small 

 feather is of use." 



The specimens figured and described are in my own collection. 



In the preparation of the above article I have examined the following specimens : —
