NOVITATES ZOOLOGICAE XXV. I'JlS. 4/ 



*2i9. Anas subbosclias Brehm = Anas platyrhyncha subboschas. 



Aims .snbboschas Brehm, Handh. Xuttirg. Vog. DenUchl. p. 864 (1S31 — Iceland). 



Type: 3 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 

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

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

 any ^4. 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 crojj, but some have, the bills are generally not narrower, 

 the wing-coverts only in some of them more grey than in A. 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. 



Querqiiedula Americana Krehm (nee .Itms amiricana Gmclin ) : /.sm, 183U. p. 90S [nomen nudum.') : 

 id., Handb. Naturg. Vdrj. DeiUschl. p. 887 {1831 — " In der Niihe von New York "). 



Type : 6 ad., New York, May 1-820. 



251. Querquedula Groenlandica Brehm = Anas crecca carolinensis. 



Querquedula Groenlaiutka Brehm, Isis, 1830. p. 998 (nomen, nudum!)-, id., Handb. Xalnrj. ]'dj. 

 DeulscU. p. 998 (1831— Greenland). 



Type : S ad., Greenland, 20. vi. 1822. 



252. Anas longicauda Brehm = Anas acuta L. 



Aruts longicauda Brehm, Handb. Saluig. Voij. Deulschl, p. 808 (1831 — " Pommem und Jlitteldeutsch- 

 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 - Spcctula clypeata. 



Clypeata mticrorhynclws Brehm, Handb. Naturg. Vog. DetUschl. p. 876 (1831 — " Sie bewuluit das 

 mittlere Europa "). 



Type : cJ ad., Auma, 8. iv. 1821. C. L. Brehm leg. 



254. Clypeata Pomarina Brehm = Spatula clypeata. 



Clypeata Pumurina Brehm, Handb. Xaturg. Voj. Deulschl. p. 878 (1831 — " Sie lebt und brutet in 

 Pommern, und auf den ihm nahe liegenden Inseln der Ostsee "). 



Type: (5 ad., Riigen, 20. vi. 1819. Schilling leg. (This specimen is inter- 

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