BIMACULATED DUCK. 
J 19 
greenish black ; front of the lower part of the neck 
and sides of the breast reddish brown, with oval 
black spots ; middle part of the breast pale reddish 
brown, also spotted with black ; ground colour of 
the mantle pale sienna-yellow, undulated with black 
lines, scapulars the same, tipped with glossy Scotch 
blue ; wing-coverts hair-brown, the lower range 
having pale wood-brown tips ; speculum dark green, 
glossed with purple; tail wedge-shaped, with the 
two middle feathers black, nam accuminate, and 
much longer than the rest, whicn are hair-brown 
margined with white ; belly and abdomen yellowish 
white, with undulating black lines most distinct 
upon the flanks ; legs and feet pale orange.” 
The somewhat lengthened shape and partially ac- 
cumulated tail of the last, leads us to a form which, 
though closely allied, has been raised to the rank 
of a sub-genus, chiefly on account of the great de- 
velopment of the tail. The bill deviates from that 
of the typical form of loschas, but runs into that 
of the species to which the title of teals was applied, 
and which were placed by many ornithologists under 
Querquedula of hay ; few species are yet known, 
and these frequent principally inland localities.
