As pointed out already above, the southwestern part of East Falkland forms a 
large peninsula, that is nearly cut off from the main island by Choiseul Sound and 
Brenton Loch. This low and almost level land is probably built up of nearly 
horizontal strata. Such is at least the case at Bull Cove and Speedwell Island. At 
Seal Cove near to the south of Choiseul Sound the dip is 4’ S. — S. 15° W. Only 
at the connection with the main island, at Port Darwin and Camilla Creek the dip is 
a little steeper; I5°S. 25°E., I2°S. 25°E., I2°S. 40°E. The prevalent rock is fine- 
grained, often thin-bedded sandstone, in some places exhibiting current-bedding and 
other indications of litoral deposit. In none of the mentioned localities — - the only 
places visited by me on this peninsula — did I find any traces of the common De- 
vonian marine fossils. But at Seal Cove and Bull Cove I collected some very indi- 
stinct and undeterminable plant-remains. On Speedwell I. my search was a little 
more successful, as I found here, partly in a pale green claystone, partly in a slaty 
sandstone, some better preserved plant-fragments, that I entered in my note-book as 
uCalamites-». As afterwards I got, together with the marine fossils at Port Louis, a 
small fragment of the same very characteristic appearance (see p. 9), in my pre- 
liminary report I considered the two deposits as being contemporaneous.' Prof. 
NathorST after our return undertook the examination of the plant-fragments from 
Speedwell I. and came to the surprising and important conclusion that they belong 
to the genus Phyllotheca and come near to a species forming a member of the 
Glossopteris-iiorà. Prof. Nathorst’s statement offers so special an interest that it 
may be quoted here verbally: 
»Ich glaubte unter diesen, allerdings sehr fragmentarischen Resten auch einen 
Asterocalainites erkennen zu können und nahm deshalb für die betreffende pflan- 
zenführende Ablagerung ein untercarbonisches oder oberdevonisches Alter an. 
Ich hatte bei meiner Angabe über das mutmassliche Vorkommen eines Astero- 
calainites allerdings nicht übersehen, dass die anderen Reste mit einer solchen An- 
nahme nicht gut in Einklang standen — es waren besonders die Reste eines 
wé’zzrzz-âhnlichen Stammfragments, die mir eigentümlich schienen — da aber keine 
Flora devonischen Alters von einer so hohen südlichen Latitude bisher bekannt war, 
konnte man ja im voraus erwarten, das eine solche gewisse Eigentümlichkeiten 
darbieten würde.
