THE BIRDS OF PORTUGAL. 213 



There is a fine specimen oftliis rare Duck in the rslus(3nm 

 of Lisbon; but Professor dii Bocage said it was very selfioin 

 found in Portugal. 



207. fCEoEMiA NIGRA (Linn.), ' Common Scoter.' 



Occurs frequently, but in no great numbers. 



208. fFuLiGULA NYUOCA (Glild.), ' Ferruginous Duck,' .V(.'7r//J/a. 



]iarely seen. 



[209. FULIGULA FERINA (Linn.), ' Pochard,' Tarrantana.'] 



[210. FuLiGULA CRisTATA (Steph.), ' Tufted Duck,' A>- 

 grinha.'\ 



[211. Clangula glaucion (Linn.), ' Golden Eye.' 



The last species is less common than the two pro- 

 ceding, which are to be met with in winter in abund- 

 ance. There are authentic specimens of all these in 

 the Museum at Lisbon.] 



212. fMERGUS serrator (Linn.), ^ Red- breasted Merganser,' 



Merganso. 

 Common. This is the only species of the Mergansers 

 which I can positively assert to belong to Portugal, though 

 doubtless others will be added on further research. 



213. fPoDiCErs NiGRicoLLis (Gmcl.), * Eared Grebe,' Mergulhao. 



214. fPoDiCEPs MINOR (Gmel.), ' Little Grebe,' Mergulhao. 



Of the abundance or scarcity of the Grebes I could obtain 

 but little information ; the Museums of Lisbon and Coimbra 

 are sadly deficient in them; but I am told that the two 

 species mentioned above are common in Alemtejo. 



[215. PoDiCEPS cristatus (Linn.), 'Great-crested Grebe,' 

 Mergulhao. 

 By no means rare; there are several specimens in 

 the Museum of Lisbon.] 



210. fCoLYMBUS glacialis (Linn.), ' Great Northern Diver.' 

 217. fCoLYMBUS septentrionalis (Linn.), ' Red-throated Diver.' 

 Of the former but few individuals have been seen on the
