of vegetation, more or less thick, with which they are usually 
bordered. 
“The recepticle for the eggs,—for it can hardly be called a nest,—is 
composed of stalks and grasses. 
“The eggs vary in number from eight to ten. They are of a pale 
buff colour, with a tinge of green. 
‘‘ The male bird leaves the female after she has begun to sit.” 
Fiinn’s remark on the cross breeding of this bird is worth noting and 
remembering by sportsmen who get hold of birds beyond their power 
to discriminate. 
“Tt breeds more freely in captivity than do Pochards in general, and 
in the London Zoologicai Gardens crossed in 1849 with the White-eye, 
the resulting hybrids continuing to breed either znter se or with the 
origina! parents for more than ten years—a fact to be remembered in 
dealing with doubtful Pochards, which should therefore, whenever 
possible, be submitted to some authority for identification.” 
Genus CLANGULA. 
The genus Clangula is a very small one, containing only three species 
of birds which range throughout the Northern Hemisphere. Of these 
three only one, Clangula glaucion, reaches India, and even this only 
occurs with extreme rarity. The most noticeable thing in this genus 
and one which at once separates it from all its closest allies is the posi- 
tion of the nostrils, which are rather nearer the tip than the base of the 
bill, the position being well shewn in the wood-cut in Blanford’s [Vth 
Vol. of Birds. In many respects in its anatomy it closely approaches 
the Mergansers, and is a sort of link between them and the more 
typical ducks.
