156. Nyroca rufina (Pall.). Ived-crcsted Pocliard. 

 Giglioli was informed tliat examples of this species had 



been taken in winter at Porto Yccehio. Further evidence of 

 its presence is desirable. 



157. Nyroca ferina (L.). Pochard. 



Winter visitor ; possibly a few breed. Whitehead 

 describes it as very plentiful in February and the beginning 

 of March, and Parrot records two adult females from 

 Ajaccio on February 4. On May 11, I saw about a dozen 

 ducks on a secluded marsh on the east coast, and was able 

 to identify at least two drake Pochards among them. 



158. Nyroca fuligula (L.). Tufted Duck. 



A common winter visitor to the east coast marshes, 

 Wharton saw thousands there in winter, and considerable 

 numbers still remained at the end of April, but on the west 

 side he saw none. Whitehead found it more common on 

 rush-covered ponds than in the lagoons. Backhouse and 

 Parrot lecord it from the Ajaccio market in January. There 

 appears to be no record at present of the White-eyed Duck, 

 Nyroca nyroca (Giild.), but it probably also occurs among 

 the flocks of ducks which haunt the east coast marshes in 

 winter. 



159. Nyroca marila (L.). Scaup. 



Whitehead found the Scaup fairly common in winter and 

 shot a drake. 



]G0. Nyroca clangula (L.) Goldeneye. 

 Whitehead saw two females in December and February ; 

 and small parties of males, from four to eight in number. 



[OiDEMiAsp? Scoter. 



Whitehead observed one of the Scoters, either 0. nigra or 

 O.fusca.l 



161. Erismatura leucocepuala (Scop.). White-headed 

 Duck. 



Apparently resident in small numbers. Wharton saw one 

 example on Lake Biguglia, and Whitehead shot a drake on
