These skius agree in size and wing-formula with typical examples, 

 biit are somewhat darker in colour, though not quite so dark as 

 G. ruhecula. I do not think, however, that the Ceylon birds have 

 the slightest claim even to suhspecific rank, as I have seen skins 

 quite as dark or darker from Nepal and Burma. 



The Orange-headed Ground-Thrush breeds in the Himalayas 

 from Nepal to Assam, apparently not ascending the mountains 

 above 50U0 feet. In the cold season it migrates to various parts of 

 Northern and Central India and Burma, occasionally straying as 

 far south as Ceylon.

This species is little more than a local race of G. citrina, Lath., 

 and it will probably be found that intermediate forms occur, in 

 which case it must be degraded to the rank of a subspecies. It is 

 a smaller bird with a more rounded wing, and darker in colour 

 than the commoner species ; the general colour of the upper parts 

 is a darker and duller slate-grey ; on the other hand, the head, 

 neck, and underparts are a darker but quite as rich orange-chestnut. 

 Wing with the third, fourth, and fifth primaries nearly equal and 

 longest ; second primary intermediate in length between the si.xth 

 and seventh, or seventh and eighth ; bastard primary 1-05 to 0-8 inch. 

 Length of wing 4-4 to 4-0 inches, tail 3-0 to 2-8, culmen 0-89 to 

 0-82, tarsus 1-3 to 1-24. 



Nothing appears to be known of the differences of plumage of this 

 species. 



Gould's Ground-Thrush appears to be confined to the island of 

 Java, where it is supposed to be a resident.
