remote from all known forms of that group, extinct or living. Habitually, the 
greatest resemblance is no doubt to the Hepaticæ with bilobed leaves, and the 
text-figures given might well be taken to illustrate representatives of that group. 
The structure of the different parts appears to have been much too thick and 
resistent, however, and it must be regarded as rather improbable that Liverworts 
of a similar type should have been preserved in this manner. Furthermore, it is 
doubtful whether the leaves are distichous as in the foliose Liverworts.

The only plant-impressions yielded by the Cretaceous series represent small frag- 
ments of a conifer, found by Prof. N0RDENSKJÖLD in marine beds near the middle 
of Snow Hill Island. The fossil has been determined by Prof. NathORST, as cfr. 
Sequoia fastigiata (Sternb.) (J. G. Andersson, /. ci). 
The best specimen is the little fragment shown in pi. 7, fig. 29. It is freely 
branching, the branches being rather short and thick. The leaves are spirally dis- 
posed and somewhat loosely imbricate. They are ovate or short lanceolate, some- 
what falcate and shortly pointed. 
In the absence of fructifications a definite generic determination is out of the 
question. It must be admitted, however, that in regard to the arrangement and 
the shape of the leaves, the specimens show a fairly great resemblance to sterile 
shoots of Sequoia fastigiata (Sternb.); and the best course is no doubt merely 
to compare them with that species. There is some difference in habit, the Antarctic 
specimens being more freely branched, with shorter branches than is usually the 
case in Sequoia fastigiata. 
Seqtioia fastigiata is a characteristic member of the Upper Cretaceous, beginning 
in the Cenomanian of central Europe and of Greenland. The fact must be empha- 
sized, however, that the present specimens do not afford any sufficient proof of the 
existence of identic species in the Arctic and the Antarctic in the Upper Cretaceous, 
not even of the occurrence of the genus Sequoia in the Cretaceous of Graham 
Land. 
There is another species to which there is a great resemblance too, viz. Cypa- 
rissidiutn cretaceum SCHENK (1875 P- 167; pi. 29, figs. lO, ii) from the Upper 
Cretaceous Gosau Beds in Northern Tyrol. The resemblance is mainly one of habit,
