80 CRATEROPODID^E. 



This species may be readily separated from the two preceding 

 by the ashy hind neck and by the entirely white abdomen. 



Distribution. The only specimens procured within my limits are 

 two which were obtained by Captain Hill's Survey party on the 

 hills of Tenasserim, apparently between Tavoy and the Siamese 

 frontier. They passed, through Mandelli, into the Hume Collection 

 and are now in the British Museum. There are other specimens 

 from Siam, Cambodia, and Saigon in the same collection and all of 

 them are alike in plumage.

Coloration. Forehead, crown, nape, back, wing-coverts, rump, and 

 upper tail-coverts olive-brown, with a fulvous tinge throughout ; 

 a broad collar on the hind neck bright fulvous : middle tail-feathers 

 like the back, the next two similar but with some black near 

 the tip ; the remaining four pahs olive-brown at base, then black 

 and broadly tipped with white ; primary-coverts black, edged with 

 hoary ; exposed parts of quills olive-brown, the earlier primaries 

 more or less hoary ; lores and a narrow supercilium white ; ear- 

 coverts white, streaked with black, sometimes entirely black; a 

 cheek-stripe from the gape continued round the ear- coverts to the 

 upper part of the eye, and a broad pectoral band, black ; chin and 

 throat whitish ; remainder of lower surface fulvous, the middle of 

 the abdomen whitish. 



Upper mandible dark horn-colour ; the lower bluish-horn at the 

 base and tip, dark brown in the middle ; mouth bluish ; iris orange- 

 brown ; eyelids and orbital skin dusky blue ; edges of the eyelids 

 orange-yellow ; legs light plumbeous ; claws pale horn. 



Length about 13; tail 5-1 ; wing 5*7; tarsus 1*9; bill from 

 gape 1*5. 



Birds from the Himalayas down to Bassein and further east 

 down to Toungngoo have the tips of the tail-feathers white. At 

 Thayetmyo both buff- and white-tailed birds occur. Throughout 

 Tenasserim none but buff-tailed birds are to be found. The ear- 

 coverts vary in colour and present every combination of black and 

 white. The black cheek-stripe is always a feature in this bird and 

 serves to distinguish it at once from the next species, which it 

 otherwise much resembles.
