ILLUSTRATIONS OF ORNITHOLOGY. 
CASARCA LEUCOPTERA, Buyru. 
Some time since, a drawing was received from Mr. Blyth of a Duck, 
which he considered to be new; and in our last communication from 
him, a second sketch was enclosed, and he informs us that he had 
received both sexes of the bird aliye from Mergui, together with 
the Argus and great Firebacked Pheasants, and other birds of in- 
terest, which were not previously known so far northward. Mr. 
Blyth considers it a true Oasarea, and has named it as above, from 
the white patch upon the shoulders. The male is rather larger than 
the female as in C. rutila, with fewer black spots and consequently 
more white on the head and neck ; the back less mottled with dusky, 
and the under parts much darker than in the female, which last has 
a strong tinge of the hue of ©. rutila. These are proposed to be 
sent alive to this country.
