232. Sheldrake. {Tadorna vulpanser.) 

 Appears in small numbers in severe winters. 



233. Ruddy Sheldrake. [Tadorna r-utila.) 



Very rare. Two instances only of the occurrence of this spe- 

 cies came to my knowledge during my stay at Corfu. The 

 bird-stufFer brought me a beautiful specimen on the 17th April, 

 1857. It was killed at Potamo, about two miles from the town 

 of Corfu. Another was killed at Santa Maura about the same 

 time. The bird- stuffier had never seen this species before. 



234. Common Scoter. [Oidemia nigra.) 



I saw a few of this species out at sea in the Adriatic, off 

 Antivari, in December 1857. It is unknown at Coifu. 



235. White-headed Duck. [Erismatura 7nersa.) 

 Common, and, I believe, resident on the lake of Butrinto and 



on the lagoons of Nicopolis. 



236. Golden Eye. [Clangula glaucion.) 

 Not uncommon in winter. 



237. Tufted Duck. [Fuligula cristata.) 

 Very common in winter. 



238. Scaup Duck. [Fuligula marila.) 



I only saw one pair of this species in Greek waters. This was 

 at Livitazza in January 1858. 



239. Pochard. [Fuligula ferina.) 

 Very common in winter. 



240. White-eyed Pochard. [Fuligula nyroca.) 



Arrives generally in March in small numbers, and breeds in 

 Epirus and Albania. Occasionally seen in winter, but far from 

 common at that season. 



241. Red-crested Whistling Duck. [Fuligula rufina.) 

 This species was common at Butrinto during the first winter I 



passed at Corfu, but I saw very few in the succeeding one. 



242. Goosander. [Mergus merganser.) 

 An uncertain and rare visitor in Epirus. 



243. Red- breasted Merganser. [Mergus servator.) 

 Not uncommon, in winter, in Epirus, Albania, and Corfu.
