84 ON THE TERTIARY FLORA OF THE ARCTIC REGION. 
Pinites, petrified by calcareous agents; a second specimen of rubbed 
wood with bored holes, having the character of driftwood : probably 
from a secondary deposit. 
4. From the north-eastern shores of the Alüksa peninsula in the 
Katmaic Sound, sub No. 87, three small fragments, with single leaves, 
of Taxodium dubium. 2: : 
5. From the eastern shores of the Alüksa peninsula (the south-west- ; ; 
ern shore of the Nukhalilek Sound) in sandstone, internally grey, ex- 
ternally reddish, two specimens, sub No. 132; the one a branch of 
Taxodium dubium; the other, merely fragments of leaves and branches 
of the same plant. 2: 
6. From the island of Unga on the shores of Alüksa (the western E 
shore of the Sacharosch Bay), from layers mixed with lignite, sub Nos. — 
210 and 223, slate, rich in oxide of iron, and externally resembling the 
spheerosiderite of the coal formation, quite filled with isolated pinne, 
reminding us of Neuropteris, the venation of which, it will be remem- 
- bered, can only be compared to that of Osmunda, or Anemia, and certain 
species of Allosurus of the existing vegetation, so that one would be 
reminded of the true coal formation, if the presence of Sequoia Langs- — — 
dorfii in the same specimen did not point to its Tertiary nature. In 3 
honour of the discoverer, I shall name it Osmunda Doroshiana. 
7, sub No. 213. From the western shores of the south-western ex^ —— 
treme end of Unga Island. Fragment of a petrified trunk, externally —— 
decomposed and whitish, internally still black, like the so-called Wood- can 
opal of the Hungarian Tertiary formation, of the same internal struc- 2 
ture, and not to be separated from my Pinites Pannonicus. The lake /^ "t 
again is identical with-Pinites Protolariz, so widely diffused in the whole | 
Miocene formation of Germany, and the first described from the lignite — ? 
formation. Tt is also a proof of the relationship of a formation so far — 
removed from us geographically. wr 
- 8. From Atcha Island, sub No. 270, a petrified bituminous wood 
(Pinites) of a Tertiary species, characterized by extremely numerous  — 
medullary rays. wr 
9, sub No. 331, two specimens of a very black, hard schist from the — 
island of Hudsnoi, near Sitcha. 
a. On one side Populus eximia, Geepp., which though only partially — 
preserved, is easily recognized; it is that form which I figured in 
t. iv. fig. 8, of the ‘Tertiary Flora of Schosnitz in Silesia,’ and which |
