*249. Anas subboschas Brehm = Anas platyrhyncha subboschas. 

 Anas svhhoschas Brehm, Handb. Naturg. Vog. Deutschl. p. 864 (1831 — Iceland). 



Type : ^ ad., Iceland, 29. iv. 1823. 



The status of this subspecies is, from the scanty material examined, at 

 present somewhat doubtful. The type in the Brehm Collection has a narrower 

 biU, but differs in no other way from typical Anas platyrhyncha platyrhyncha. 

 An adult male collected by H. H. Slater has the upper wing-coverts as grey as 

 any A. platyrhyncha conboschas from Greenland, but otherwise agrees with 

 A. p. platyrhyncha. Two males from North Iceland, collected by C. B. Dinesen, 

 have black spots on the crop, grey upper wing-coverts like A. p. conboschas, one 

 of them also the coarser markings on the sides as in the latter. Five males in 

 the British Museum have the same markings on the sides as typical platyrhyncha, 

 and I cannot see any other differences from the latter either ; most of them have 

 no black spots on the crop, but some have, the bills are generally not narrower, 

 the wing-coverts only in some of them more grey than in ^. p. platyrhyncha. 

 Wings 266-290 mm. Only two females could be examined, so far ; both have 

 a heavily spotted underside. 



250. Querquedula Americana Brehm = Anas crecca carolinensis.

 id., Handb. Naturg. Vog. Deutschl. p. 887 (1831 — " In der Nahe von New York "). 



Type : (J ad.. New York, May 1820. 



251. Querquedula Groenlandica Brehm = Atuis crecca carolinensis. 



Querquedula Groenlandica, Brehm, Isis, 1830. p. 998 (nomen nudwn !) ; id., Handb. Naturr/. Voj. 

 Deutschl. p. 998 (1831— Greenland). 



Type : c? ad., Greenland, 20. vi. 1822. 



252. Anas longicauda Brehm = Anas acuta L. 



Anas longicauda Brehm, Handb. Naturg. Vog. Deutschl. p. 868 (1831 — " Pommern und Mitteldeutsoh- 

 land "). 



Type : S ad., Konigswartha in the Lausitz, 20. iv. 1817. 

 This specimen agrees so perfectly with the description that the latter must 

 have been taken from it. 



253. Clypeata macrorhynchos Brehm — Spectula clypeata. 



Olypeata macrorhynchos Brehm, Handb. Naturg. Vog. Deutschl. p. 876 (1831 — "Sie bewohnt das 

 mittlere Europa"). 



Type : <? ad., Atlma, 8. iv. 1821. C. L. Brehm leg. 



254. Clypeata Pomarina Brehm == Spatula clypeata. 



Clypeata Pomarina Brehm, Handb. Naturg. Vog. Deutschl. p. 878 (1831— "Sie lebt und briitet in 

 Pommern, und auf den Uim nahe liegenden Insein der Ostsee "). 



Type : <? ad., Riigen, 20. vi. 1819. Schilling leg. (This specimen is inter- 

 esting, beginning to moult already into the eclipse plumage.)
