DUCK, BIMACULATED. 
ANAS GLocITaNns, Gmel, 
This species is said to inhabit Asia, and but few 
specimens have been met with in England. Of 
these one, a male, taken in a decoy in 1771, was 
described and figured by Pennant. A male and 
female, caught in the same manner near Maldon 
in Essex, in 1812, were described by Mr. Vigors, 
and presented by him to the Zoological Society. 
Of its habits and nidification nothing is known. 
DUCK, BUFFEL-HEADED. 
FULIGULA ALBEOLA, Audobon. 
This species is not uncommon in North America, 
where, besides other localities, they are found in 
the fur country, and also on the streams of the 
Rocky Mountains. Two or three specimens 
have been captured in Great Britain, and 
there is reason to believe that others have been 
seen during winter in the water about Yarmouth. 
Its shy disposition and wary habits, conjoined 
with its wonderful expertness in diving, rendering 
it very difficult to approach, may in some measure 
account for the small number taken in this coun-
