1911, at Tubi, Campbellpur. The orange tint in the bill of this 

 bird was very distinct when first seen by me in Angust in 1911. 



Distribution . — " Breeds in the timdras of Eastern Siberia from 

 the Lena Delta eastward." " During migration it is met with as 

 far West as Dzungaria " (Butmiin.) Ifc extends South during 

 winter into Central Asia and, as above, into India and China, 

 whence I have seen a skin collected by LaTouche. Probably the 

 majority of reported occurrences of heivichi in China and Japan 

 should refer to this species. A swan seen by Major Harington 

 near Maymyo, in the Shan States, may have been of this species.

Description. — When adult this swan can always be distinguished 

 at a glance by the knob at the base of the bill, but at all ages it can 

 be determined by the black lores. 



Occurrences in India. — (1) Skin in British Museum, shot by 

 W. Mahomed Umar, January 1857, in the Shah Alum River, Punjab. 

 (2) Two young birds shot by Captain Unwin on the Jubee Stream,. 

 North-West Provinces, January 1871. Skins in the British 

 Museum. (3) Three birds, the skin of one of which is in the British 

 Museum, shot by Mr. E. H. Watson in the Sewan District of 

 Sind, on the 12th February 1878. The same year many more were 

 seen and in five cases a pair were shot, but no skins preserved. In 

 June of the same year out of a flock of these birds, one was shot 

 by Major Waterfield and one by Mr. D. B. Sinclair, and on the 7th 

 July the latter gentleman saw another swan in the Gulabad Jheel,
