326 BIRDS OCCURRING IN INDIA NOT DESCRIBED 



dove-coloured, brown feathers ; the rest of the lower surface 

 is pale brown, becoming albescent towards the vent, each fea- 

 ther broadly centred, (most conspicuously so on the sides and 

 breast), with dingy white ; the ruff, of long linear lanceolate 

 feathers, is a very pale fulvous white, faintly margined with 

 brown ; the mantle, a somewhat pale hair brown, every feather 

 narrowly but conspicuously, centered with fulvous white ; the 

 quill-feathers and tail-feathers chocolate brown, darkest on the 

 primaries and rectrices ; the lower back, rump, and upper tail- 

 coverts are nearly pure white, only a few of the longest of the 

 latter being tinged with brown. 



In an intermediate stage, the crop patch is intermediate in 

 colour between that of the adult and of the young, as is also 

 the colour and character of the ruff, and indeed of the whole 

 plumage. 



This bird differs at all ages from bengalensis, in having 

 fourteen instead of twelve rectrices. — Hume, st Hough Notes."" 



4 ter. — Gyps tenuirostris, Hodgson. 



In plumage this species closely resembles the Eastern Gyps 

 indicus,* but differs in the much slenderer bill and head. The 

 following are dimensions and colours of the soft parts of a speci- 

 men shot by Dr. Scully in the Residency grounds, Khatman- 

 doo, Nepal. 



Length, 38 - 5 ; expanse, 89*5 ; wing, 23'4 ; tail from vent, 

 10*7 ; tarsus, 3-9 ; bill from gape, 2'85 ; weight, 121bs. 



Bill brownish dusky horny ; the culmen yellowish horny ; 

 cere horny black ; irides deep brown ; skin of head and neck 

 dark muddy ; tarsi and toes black ; edges and interspaces of 

 scales earthy ; claws dusky or horny black. 



From pallescens this species differs, not only in its slenderer 

 head and bill and its darker plumage, and in the amount of 

 feathering on the head and neck, in which two latter respects 

 it agrees with indicus, but also in the wholly different coloring 

 of the soft parts.
