It differs from O. I. leucolophus, in having its under plumage rufous 

 instead of olive-brown, and is a smaller bird than O. I. diardi. 



[The nest and eggs, of which I have many, cannot be distinguished from 

 those of leucolophus. — E.C.S.B,]

Description as in Gates, F. B. I. 



Distiihution. — Siam, Cambodia and within Indian limits, cis-Salween 

 Maukmai, S. S. States, and the frontier range between Tenasserim and 

 Siam. 



[The nest is exactly like the nest of the two preceding birds, but the 

 eggs average a trifle larger — E, C. S. B.]

Description as in Gates, F. B. I. 



Mr. Gates draws attention to the variation in the colour of the ear-covert, 

 these may vary from black to almost pure white in birds from the same 

 locality. The only variation that seems to hold good, is that of the Tenas- 

 serim birds which have buff-coloured tips to the tail feathers, those from the 

 Himalayas and other localities have the tails tipped with white. 



Distribution. — From Nepal to Assam, thence through Burma to 

 Tenasserim.

There is only one specimen of this so-called sub-species from Sikhim, 

 where G. pectoralis also occurs, and is in all probability a case of individual 

 variation.

Distribution. — Practically the same as G. pectoralis. Both these species 

 are found at low-elevations, and consort together in parties, and although so 

 very alike are quite distinct, and easily separable by size, 



* Allied sub-species. 



G. bicolor, Hartl- From Sumatra. 



Very noticeable for its rich almost chocolate colour, it however belongs to this 

 jyroup of the Laughing Thrushes with a noticeable white crest.
