This is a fairly well-defined species, and combines the characters 

 of G. lunuJata and G. pnpuensis, from either of which it is, how- 

 ever, easily distinguishable. Curiously enough, it appears to come 

 nearest in coloration to G. nihjiriensis. The general colour of 

 the upper parts is russet-brown, both on the head and back, as 

 well as on the rump, with the \isual black crescentic tips to 

 the feathers, and the usual markings on the wings and tail. As 

 in the last mentioned species, the subterminal ochraceous spots 

 are more developed than in the two first mentioned species, 

 especially on the head and nape. From G. iiapuensis and G. heinii 

 it may at once be distinguished by the outside tail-feathers, which 

 are narrowly, not broadlj', tipped with white. From G. nUgiriensis 

 it may be best distinguished by the decidedly buff' basal portion of 

 the inner webs of the secondaries and many of the primaries, which 

 in the South-Indian species are white. Bill dark brown, paler at 

 the base of the under mandible. Wing with the third, fourth, and 

 fifth primaries nearly equal and longest, second primary about equal 

 to the sixth, bastard primaiy 1'2 to 1-1 inch. Length of wing 

 5-3 to 5*1 inches, tail 4*4 to 4-25, culmen 1"2, tarsus 1-45 to 1-35. 

 Nothing is known of the changes of plumage which this species 

 undergoes.
