82 ON THE TERTIARY FLORA OF THE ARCTIC REGION, 
Trap formation of the Faróe Islands, especially in Suderóe, lignite 
occurs under very similar conditions. Whether the bituminous and . 
petrified woods, found by M‘Clure in Banks Island, lat. 75° N., may 
here be classed, I am unable to say. 
III. In August, 1859, M. von Pander and General yon Hofmann 
forwarded to me a rather extensive, but unfortunately rather imperfectly 
preserved collection of fossil plants, which Lieut.-Col. von Doroschin 
made in the Alüksa peninsula, the western part of Russian America, 
and on the adjacent Aleutian islands, Kodják, Uyak, Atcha, and — 
Hudsnoi, about lat. 59? N. By far the greater part belongs to the - 
Tertiary, a smaller to older formations. d 
A. Tertiary Formation. 
1, sub No. 10. Four pieces in a grey, rather hard, slightly calcareous 
and slaty rock, said to be from strata which are mixed with lignite, - 
from the Bay of Ugolni, a part of the Kenaic Sound of the Aläksa — 
peninsula. Three specimens of leaves, all of them only accidentally 
preserved in the central parts,—leaves with stiff, acutangular lateral 
veins, such as we have in Carpinus. A more certain determination iso 
impossible, although they doubtless belong to already described species. 
Nor can the fourth specimen, a stem with parallel striæ, similar to 
Phragmites Œningensis, Heer, but without modes, be determined with 
more certainty. 
2, sub No. 11. Eleven specimens, in a soft and fragile clay, of a — 
light grey colour, and very similar to that of Oningen, and more espe- — 
cially that of Schosnitz ; according to M. von Doroschin, collected near — 
the village of Neniltchik, on the eastern shores of the Kenaic Sound, - 
and in strata mixed with lignite. - 
a. The central part of a willow-leaf, perhaps that of Salix Wim- 
meriana, a species which I cannot unite, as Heer has done, with Saliw 
varians, and which, in the rounded form of its base, differs much more — 
from 5. varians than Heer’s S. macrophylla from S. varians ; the latter — 
I have seen of the same size as Heer did at Oningen in Schosnit2, 
without being able to regard it on that account as a distinct species. - 
Pieces of S. caprea, cut or broken off, I saw making leaves 6 inches — 
long and 24 inches broad. x 
- 4. Leaf of a Salir not quite agreeing with any known species, but — 
coming nearest to S. integra, Geepp., which is found besides at Üningen —
