328 LARUS SP. INCERT. 
to Larus glaucus and L. islandicus, and Herr Nordvi shewed me eggs 
so marked by Dr. Kjzerbélling which had been sent to him thence 
for identification. However, I could see nothing nearer the supposed 
species than the Herring-Gull during my visits to the islands, and 
indeed at my last interview with Herr Nordvi he asserted that they 
were Herring-Gulls’. It is said that occasionally there will be eight 
or ten nests with eggs of this character found in a season on Horno. 
They are much valued by the people for exportation. 
[Pastor Sommer‘elt subsequently came to the same conclusion (#fv. K. 
Vet.-Akad. Férhandl. 1861, p. 84); but some of the eggs from the islands off 
Vardé seem to be too big for Larus argentatus, and are quite big enough for 
LL. marinus, to say nothing of the fact that Z. fuscus breeds also in the same 
islands. I therefore prefer leaving them as uncertain, but they are much too 
beautiful and curious to omit. A series may be traced beginning with the almost 
colourless or extremely pale blue examples, not unfrequently occurring in 
Gulleries where the eggs are very much robbed, to examples shewing a slight 
blush of pink in the ground-colour, intensified in the spots or blotches into light 
red, and so till highly ruddy hues are reached. A similar style of coloration 
is presented by the ordinary eggs of Anous and Sterna fuliginosa; and the case 
seems analogous to that of certain Corvide, as before mentioned (§ 2796). }

[§ 4597. One.—Fugl6, West Finmark, June, 1594. From 
Colonel Feilden, 1895. 
Colonel Feilden wrote to me:—“In July last I saw a basket full of eggs 
exposed for sale to tourists in a shop at Tromsd. The owner told me they 
were brought from Fuglé and Arno. In the basket which contained only 
Guillemots’ and what might be either Lesser Black-backed and Herring-Gulls’, 
I detected the accompanying red egg....The man could not possibly have 
any object in saying that the eggs came from Fugl6 if they did not do so.
