Genus XXXIX. RECURVIROSTRA, Linn. 
R. Avocetta, Temm. Man. d’Ornith. p.590. 
Scoopinc AvosEtT.—I have inserted this species on the authority 
of Donovan, who, in his History of British Birds, (Pl. 66.) speaks 
of it as being common in the breeding season in the fens of 
Cambridgeshire. It is very probable that this was formerly the 
case, when our marshes were more extensive than they are at 
present, but I have not been able to learn that it is ever met 
with now. ’ 
Genus XL. NUMENIUS, Briss. 
N. arquata, Temm. Man. d@Ornith. p.603. 
Common CurRLEW.—Sometimes seen in small flocks about New- 
market Heath.

Genus XLI. TRINGA, Briss.

Dunuin.—These birds now and then visit our fens during the 
summer months, and it is not improbable that they may breed 
in those situations. In the beginning of July 1824, they were 
very abundant. Several which were then killed and came under 
my observation, I found to answer, in most particulars, pretty 
correctly to Temminck’s description of this species, as it appears 
in its summer plumage. The black, however, on the under parts 
was very variable in different specimens, some of which were only 
faintly spotted with this colour, whilst in others the whole of 
the belly and abdomen were thickly blotched over with large 
irregular patches of the same, but in no case without some 
mixture of white. From this last circumstance it is likely, that 
at the time above-mentioned, the season of incubation was just 
over, as, according to Temminck, so long as that lasts, the belly
