has been more frequently met with amongst the London 
poulterers, probably from an increased activity in the regu- 
lar shooters of wild fowl, in their search after curious birds ; 
and hardly a season now passes without producing speci- 
mens of this and other rare species of the Anatide, &c. It 
is anative of the same countries as the Red-breasted Pochard, 
inhabiting the eastern parts of Europe and Northern Asia, 
our island appearing to be the limit of its wmter migration to 
the westward. Fresh-water lakes and rivers are its usual ha- 
bitats, it being rarely found on the sea-coast.—Its food consists 
of insects, aquatic plants, seeds, &c. which are principally ob- 
tained by diving.—It breeds in the higher latitudes of nor- 
thern Asia, in the reeds, &c. that fringe the edge of their 
lakes and rivers, making a nest of dried vegetable matter, 
and laying from eight to ten greenish-white eggs. The for- 
mation of the trachea, according to the descriptions of Mon- 
Ttacu, TEmMINckK, and others, bears a strong resemblance 
to that of the Red-breasted Pochard, the tube being con- 
tracted a little below the glottis, and again near to the lower 
larynx, and the middle part swelling out to a much larger 
diameter. The tympanum differs, however, from that of the 
two preceding species, in having the side next to the trachea 
almost entirely osseous; the other side being covered by a 
membrane intersected or supported by a bony arch.
