COLYMBUS ARCTICUS, Linnzus. 
BLACK-THROATED DIVER. 
§ 4971. One.—Loch Scatavagh, North Uist, 5 June, 1847. 
From Mr. Henry Milner. 
Brought to me this 26th of October, 1847, and [the name of the 
place] written on it by Mr. Henry Milner at Beeston. This valuable 
egg is one of the only pair the Messrs. Milner met with on this loch, 
though they found the bird on many of the large lochs [in Sutherland 
and Ross (‘ Zoologist,’ 1848, p.2017)j. Mr. Milner wrote of this egg 
on the 2]st that “It was taken by my own hands.” Sometimes the 
bird makes a considerable nest, often scarcely any. The eggs vary in 
colour. Mr. Milner did not find this bird in Iceland. I hear that 
Mr. Strickland has attempted to prove that the Norwegian Black- 
throated Diver is different from ours—see British Association 
Report. 
[In Mr. (afterwards Sir William) Milner’s paper in ‘ The Zoologist’ for 1848 
(p. 2061), Loch Ean is given as the place where this egg was taken; but 
Mr. Harvie-Brown kindly informs me that that loch, the name of which is 
more correctly written Loch nan Eun (Lake of the Birds), may be easily and 
pardonably mistaken for Loch Scatavagh, the name inscribed on the egg by 
Mr. Henry Milner, owing to their proximity and the extraordinary ramifica- 
tions of the latter, though the two are not connected. 
I find nothing in the Reports of the British Association to bear out the 
truth of the rumour which Mr. Wolley mentions; but there may have been 
some communication by one or other of the Messrs, Strickland to the effect 
stated, and it may have been noticed in some newspaper of the time. In 1824 
C. L. Brehm described (Lehrbuch der Naturgeschichte aller europiischen 
Vogel, ii. p. 888) a “ Colymbus balticus, Hornschuch et Schilling ”, from infor- 
mation given to him by those naturalists; but from what he subsequently 
wrote (Handbuch u. s. w. p. 976) it seems that the supposed new species had 
its home in South-eastern Russia, only visiting the Pomeranian coast of the 
Baltic in winter, and nothing is said of its occurrence in Norway, though the 
rumour, if true, probably had its origin in this alleged species, which has been
