tbe rhizome of a Dictyophyllum. Denticulation is visible on a 
fragment of Cladophlebis Nebbensis, as in an Austrian specimen of 
Cladophlebis. Tbe leaves of Gutlieria are constantly found with 
fmctifi cation. Sagenoptcris, Otenopteris, and Thimfeldia are very 
rare. The occurrence of genuine Dictyophyllum Muensteri and I). 
Ni/ssoni may be doubted, tbe Piilsjö specimens of tbis last species 
having less regulär and sborter secondary Segments, althougb not as 
short and broad as those of I). acutilobum, Schenk, but perfectly con- 
cordant witb the Transsylvanian Campt. Nilssoni. Perliaps tbe 
Piilsjö species shows transitions to Dictyophyllum rugosum, and D. 
Leckenbyi may be admitted as a distinct species under tbe name of 
D. polymorphum. 
Tbe nerves of Nilssonia polymorpha are invariably simple, and tbe 
lamina covers completely tbe upper side of the rbaehis. In all tbe 
Pterophylla, from tbe Trias up to tbe Cretaceous, tbe segments are 
laterally attacbed to tbe rhachis, not covering it completely, and a 
certain number of nerves at tbe base are dichotomous ; good dis- 
tinctive generic characters. There are, however, transitional forms, 
such as Pterozamites Blasii, Braun. Cycadites longifoliux, somewhat 
reminding us of tbe Chinese Taxites spathulatus, Newb., may possibly 
be a Conifer. Tbe least frequent variety of Podozamites clistavs 
is tbe typical form, genuina. Podozamites ovalis, Nath., may be a 
variety of Podoz. clistavs. Tbe Strobili of Schizolepis are generally 
so much worn by rolling that tbe division of tbe scales is indis- 
tinguishable. 
3. Fossil Plants from Eastern Siberia. — By Dr. St. T. Schmalhausen. 
(Imp. Geol. Inst. Vienna, Meeting of January 23, 1877.) 
In 1873, Mr. Lopatin, a Bussian Mining Engineer, discovered, 
among tbe pebbles of tbe River Ogux (an affluent of the Yenisei), 
impressions and casts of plants in fragments of sandstone. Tbe 
species, as far as they can be ascertained, are : 
Bornia radiata (Brong.). 
Filicitcs . Ogurensis, Schmalh. 
Lepidodendron Veltheimianum, St. 
Bergeria regularis, Schmalh. 
„ alternans, Schmalh. 
Lepidodendron WiiJcianum, 0. Heer. 
Lepidostrobus gracilis, Schmalh. 
Knorria, sp. 
Cyclostigma Kiltorkense, Haught. 
Stigmaria ßcoides , St. 
Tbe presence of Cyclostigma Kiltorkense proves these remains to 
bave belonged to tbe Lower Carboniferous.

They occur in shales, intercalated between brownisb, yellowish-
