88 THE BARRED-HEADED GOOSE. 
told that these Goose eggs are found also at the edge of the 
Salt Lake itself.” 
Again Prjevalsky say :— 
“We found this beautiful Goose at Lake Kokonor where 
the first migrants appeared on the 5th of March; and in the 
course of the whole month small flocks of from five to twelve 
in number are to be seen frequently. Also at the sources of the 
river Tetunga we saw some A. zndicus, which were breeding 
there ; and a female, which we killed on the 6th of April, was 
already laying. 
“In spring the male chases the female on the wing, and 
occasionally makes peculiar darts, resembling those of our 
Common Raven, and when the female is shot, the male usually 
flies long about its dead mate, until it shares the same fate.” 
I HAVE measured and weighed a very large series of this 
species. The males average appreciably larger than the females 
of the same age, but they take some years to attain their maxi- 
mum dimensions and weight, and many females are, therefore, 
as large or larger than many males, and it seems therefore 
useless to give the dimensions of the two sexes separately. 
Apparent adults varied as follows :— 
Length, 27°25 to 335 ; expanse, 56 to 66; wing, 16°0 to 190; 
tail from vent, 5°0 to 7°0; tarsus, 2°5 to 3:3; bill from gape, 1°38 
to 2°3; weight, 4 lbs. to 6 lbs. 14 ozs. 
I have weighed I find more than a hundred; but I have 
never obtained one weighing quite 7 lbs.; yet Jerdon gives the 
weight as 7 lbs. to8 lbs. Only two of my specimens exceeded 
6 lbs. 8 ozs. The great majority are less than 6 lbs. 
The legs and feet are bright orange, sometimes paler, occa- 
sionally only yellow ; claws horny black ; the irides deep brown ; 
the bill orange yellow to orange, rarely only pale, lemon yellow 
often paler or greenish towards the nostrils ; the nail black or 
blackish. 
There is a prominent tubercle nearly half an inch long in old 
males, just below the carpal joint, varying in size according to 
sex and age, but always more prominent than in the Grey Lag, 
and other Geese already mentioned. 
THE PLATE, though a little coarse, and on the whole rather too 
brown, is good, though the bill is generally more orange. The 
bird in the foreground is a gosling about three months old 
obtained in September in Tibet. This has never been figured 
before, and is so unlike the adult that it may be well to subjoin 
a description. 
It differs from the adult altogether in the head and neck 
markings. The bill is, as inthe adult, yellow, but with the nail 
deep brown ; the legs and feet appear to have been a brownish 
orange ; the forehead is brownish white, a little tinged with
