304 STERNA FLUVIATILIS.—S. MACRURA. 
[§ 4440. Sivz.—Nova Scotia. From Mr. R. Downes, 1853. 
Sent to me as eggs of the “Great Tern,” 7. e. the 8. wilsont of those days, now 
said to be identical with the European bird. Mr. Downes was a careful man. | 
[§ 4441. Four.—New Jersey. From Dr. Heermann, 1861. 
Whether Dr. Heermann or his collector was as careful to determine the 
parentage of his Terns’ eggs as he ought to have been is more than I can say; 
but in the case of these he most likely assigned them to the right species. ] 
[§ 4442. One.—Dybs6, Denmark, 26 June, 1893. 
My brother Edward wrote that having gone to this island he found there 
very many Common Terns and their young. “TI picked up,” he continues, 
“an egg, marked like a Sandwich Tern’s, which must belong to the Common 
or Arctic Tern, but both HH. Olsen and Fahrenholtz,” his companions on this 
occasion, “assured me that the Arctic Tern is not in Sjelland, only in the 
north of Jylland. I was afterwards told by Herr Winge that the Arctic is 
found near Copenhagen in summer,” Herr Grénvold informs me that he 
has shot S. macrura at Dybsi, but he could not say that it was breeding 
there. Herr Scheel’s statement (Neestvedegnens Fugle, p. 45) that its downy 
young are found there is hardly convincing, since he thought they were 
distinguishable by their colour from those of S. fluviatilis, which I believe 
is not so. ] 
*,* [The collection contains an extensive series of Terns’ eggs, taken in 
various places, which it is impossible to refer to either the Common or the 
Arctic species, but they undoubtedly belong to one or the other, and no person, 
so far as I know, has ever been bold enough to discriminate between the eges 
of the two. The series shews some very beautiful variations from the ordinary 
types, and I much regret that the specimens in it were not determined. |
