Stachyrhis nigriceps coltarti, Harington. 



The Assam Black-throated Babbler. 

 Harington, Bull., B. O. C, xxxiii., p. 61 (1913). 



Desaiption. —KAnlt : Similar to S. nigriceps, Hodgson, from Nepal, but 

 differs in having the throat very dark grey or black ; in S. nigriceps the 

 feathers are dark grey edged with white, producing a striped appearance. 

 The measurements are the same as those of ^S". nigriceps. 



Habitat.— T>ihxng&Th., Assam; the Naga and Chin Hills, and the Bhamo Hills. 

 Birds from the Shan States and Tenasserim have the throat light ashy-o-rey, 

 as in S. davisoni, Sharpe, from the Malay Peninsula, with which they appear 

 to be identical. 



I have named this sub-species after Dr. H. N. Coltart, who has collected a 

 number of specimens at Margherita, Assam. 



Type in the Tring Museum: $ . Margherita, 4,xii. 01. H. N. Coltart coll. 



* Stachyrhis nigriceps davisoni, Sharpe. 

 The Tenasserim Black-throated Babbler. 



Stachyrhis davisoni, Sharpe, Bull., B. O. C, i., p. 7 (1893). 



Description. — Chin and throat ashy grey, and not black and white ; lores 

 and forehead hoary grey ; ear-coverts hair brown ; superciliary streak sooty- 

 brown to black, upper plumage tinged with green. 



Bill intensely black, bluish belo\v. 



Distribution. — The Malay Peninsula, and probably up to Karennee, one 

 specimen procured at Thandunng ( now in the Tring Museum ) is, I think, 

 referable to this sub-species. 



Note. — Birds from the Shan States appear to be this sub-species, but differ 

 slig'htly as follows : upper plumage with a decided rufous tinge ; the chin and 

 throat pale ashy ; ear-coverts golden -brown ; superciliary streak black with 

 white edges to the feathers and very conspicuous. 



Bill bluish to black below, intensely black above. 



Stachyrhis chrys^a. 



Colouration. — Lores and in front of the eye, black to yellowish ; forehead 

 golden to pure yellow ( in chryscea and chrysops and binghami, a short mousta- 

 chial streak black ) ; ear-coverts greenish -yellow to the same colour as the 

 head, and slaty-green in binghami ; crown and nape bright golden yellow to
