562 ERISMATURA LEUCOCEPHALA. 
§ 5628. Two. 
6th of May, 1817, at Hockwold in the county of Norfolk; the female had 
a perfect egg in her; from which circumstance, they would doubtless have 
bred in that neighbourhood. This fact proves what has not been before 
ascertained: that some of this species continue in England the whole year.” 
Hunt was a bird-stuffer at Norwich, and must have been known to Mr. Scales, 
at that time living in Norfolk. Such an occurrence is not likely to have 
happened twice. It is reported by Sheppard and Whitear in their ‘ Catalogue 
of Norfolk and Suffolk Birds’ of 1825, and also by Mr. Sonthwell in his 
continuation of Stevenson’s ‘ Birds of Norfolk’ (iii. p. 178).] 
ERISMATURA LEUCOCEPHALA (Scopoli). 
Lake Halloula, Algeria, 11 June, 1856. From 
Mr. Tristram’s Collection. 
[These formed Lots 268 and 269 at Mr. Stevens’s auction-room, 9 February, 
1858. Writing of this locality and time, Mr. Tristram says (Ibis, 1860, 
p- 163) :—“ We found two nests of the White-headed Duck (Zrismatura 
mersa) among the sedge, containing the one three, the other eight eggs. These 
are very large for the size of the bird, almost perfectly elliptical in shape, and 
a line longer and wider than those of the Velvet Scoter, of an extremely 
rough texture, unlike that of any other Duck, more resembling the egg of the - 
Bean Goose, but far more coarsely grained, and of a dull white colour. The 
habits and flight of the bird are more like those of a Grebe than of a Duck; 
it often saves itself by diving, and remains under water for a considerable 
time. |

(§ 5631. One.-—San Lucar. From Mr. Howard Saunders, 
1869. 
In his “ Notes on the Birds of Southern Spain,” Mr. Saunders (Ibis, 1871, 
p. 397) only says of this species that it is “ Resident, and common in the 
lower ‘ Marisma,’ near San Lucar, where it breeds, but rare in the vicinity of 
Seville.”]
