WATER FOWL OF INDIA AND ASIA. 13 
Bewick’s Swan. 
Cygnus bewicki, SALVADORI, Brit. Mus. Cat., Birds, Vol. 
SOXVIL p20: 
Is very like the Whooper, but decidedly smaller, and has 
the yellow on the base of the bill less extensive, and terminat- 
ing rather abruptly ; it does not reach the basal end of the 
nostril, whereas in the Whooper the yellow runs on below 
the nostril and ends in a point. 
This species has much the same range as the Whooper, but 
does not breed so far west in Europe, though visiting Britain in 
winter. Like the Whooper, it is found in China and Japan at 
that season, and although not yet known to occur in India, will 
probably be found to do so, sooner or later. The eggs are like 
the Whooper’s, but smaller. The bill in this species is little over 
three-and-a-half inches long, and the shank barely four, while 
the closed wing is about a foot-and-a-half. The total length is 
about four feet. 
Pere Davie’s Swan. 
Cygnus davidi, SALVADORI, Cat. Birds, Brit. Mus., Vol. 
XXVII. 
Is a very mysterious bird, only one specimen being on 
record, which was seen by that excellent ornithologist, Swin- 
hoe, in the Museum of the Lazarist Mission at Pekin in 1868; 
the specimen had been bought in the market at Tientsin. 
It was smaller than Bewick’s Swan and was all white with 
red bill tipped with a black nail, and orange-yellow feet. 
No other specimen has since been obtained, and it is just pos- 
sible that the specimen seen by Swinhoe was one of an expiring 
species, which has now disappeared altogether. It must not 
be forgotten that a conspicuously coloured diving-duck (Camp- 
tolemus labradoricus) tormerly well known in North America, 
has completely disappeared in our time, and there are not nearly 
sO Many specimens of it in Museunis as there are of the Great.
