Description. — This cluck is intermediate iietween tlie Indian and Chinese 

 birds, and is in general appearance very close to the former, from which it 

 differs principally in having no red spots at the base of the hill, or onh' a 

 faint trace of them. 



The under-parts are pale as in pircihjrJnjnclin, but less spotted, and the 

 speculum is green as in that bird instead of blue as in SDiwrlii/nclia. 



It is a slightly smaller bird, the bill averaging only 2'05, and the wing 

 10'25 inches. 



Distribution. — The whole of Buriua, including Shan States and 

 Chin Hills, Yunnan, Cochin China and the extreme east of Assam. 



Stevens got a number of these ducks in North Lakhimpur. In 

 190'2, Messrs. Moore and Muudy got several specimens in Dibrugarh, 

 and each succeeding year up to 1905 got others. I obtained my 

 first specimens in 1903, and got a good many more in 1904 and 

 1905. 



Nidification. — The Eastern Grey Duck is of course resident where 

 found, and breeds throughout its range. I took its eggs, three fresh, 

 in Dibrugarh, and Harington took a hard-set clutch of eggs in the 

 Shan States. 



The eggs differ in no way from those of the spot-bill, but average 

 smaller. 



My eggs measure 550 X 39-5 ; 5(3-5 X 38-5 and 58-7 X 41-0 

 mm. 



These are shown by Hartert as the eggs of zo)iorhyncJia, as at 

 the time I wrote to him I did not admit Jiariiiytuni as a separate race.
