8870 Natural-History Notes 
the redwing, but it was evidently too late to secure eggs of this 
species. Several times nests were found closely resembling those of 
the song thrush, with particles of blue eggs, undistinguishable from 
those of the thrush: these were, in all probability, nests of the red- 
wing, and were placed in similar situations to those chosen by the 
common thrush. What makes this the more probable is that the 
song thrush is a very rare bird so far north. 
Ferns in great variety were noticed all over the country. In no part 
of Great Britain or in Germany have I seen the beautiful Polypodium 
Dryopteris so plentiful and fine; fronds of twelve and fifteen inches 
were frequently noticed. Lastrea Filix-mas, L. Oreopteris, Pteris 
aquilina, Athyrium Filix-foemina, Asplenium septentrionale, Cystopteris 
fragilis, Polypodium vulgare and P. Phegopteris, were also seen in 
profusion. Near the Odde Glacier I noticed, where the snow had 
only disappeared a few days before, a luxuriant growth of Polystichum 
Lonchitis. In the low grounds by the road-sides we frequently 
passed whole acres of Struthiopteris germanica, with fronds three and 
four feet high. Osmunda regalis and Cryptogramma crispa were seen ; 
and in the crevices of the rocks luxuriant masses of Woodsia hyper- 
borea, Asplenium Trichomanes and A. viride. On one occasion, in 
driving along the road I fancied I saw Asplenium fontanum. In the 
neighbourhood of Drontheim, and throughout the Guldbrandsdal, is a 
large aconite in great profusion: the plant seemed to me to be much 
larger, with more deeply cut leaves, and a more lurid blue flower 
than A. Napellus. The beautiful Arnica montana abounds in all the 
meadows; Anchusa tinctoria, Impatiens Noli-me-tangere, and other 
plants, unknown to me, were frequently seen on the road-side. 
Norway is indeed a paradise for the botanist. 
Doritis Apollo. During two previous trips to Norway a few weeks 
later in the year I frequently saw in one day’s drive twenty or more 
splendid specimens of Doritis Apollo in the meadows by the road side. 
J had no net with me, but often jumped from the carriole and secured 
specimens by knocking them down with my hat. In flight they resem- 
bled nothing so much as animated pieces of tissue paper. Argynnis 
Lathonia is not uncommonly seen alighting on the sandy ground. I 
noticed also Limenitis Sybilla, Vanessa Atalanta, Satyrus Semele, 
Gonepteryx Rhamni and other butterflies, as well as Macroglossa 
Stellatarum. 
Golden Plover and Godwits are found in great numbers on the 
Dovrefjelds. I first noticed the former birds with black breasts near 
Hjerkin. Engaged in procuring specimens of some beautiful alpines,
