NETTION CRECCA, Kaup. 
English Teal. 
Jlnas crecca, Linn. Syst. Nat. I, 1766, 204.— Gmelin, 1,1788, 532.— Temminck, Man. II, 846. 
Querqucdula crecca, Stephens, Shaw’s Gen. Zool. XII, i, 1824, 146. 
“ Nettion crecca, Kaup, Entw. Europ. Thierw. 1829.” 
Sp. c H . —Similar in size and general appearance to Nettion carolinensis. No white crescent in front of the bend of the wing ; 
the elongated scapulars black externally ; internally creamy white. 
Hab. —Europe. Accidental on the eastern coast of the United States.

running very near the anterior and superior outline of the side of the head, are quite distinctly 
whitish, instead of being merely obsoletely paler, as in the other. The transverse hands of the 
upper parts and sides are more sharply defined and rather more distant. The hand at the end 
of the greater coverts is broader and whiter, that at the end of the lesser is narrower. The
