which are in both cases quite similar. The upper part of the specimen mentioned 
is different and bears some larger scale-like appendages. These consist of a very 
short petiolar basal part and a broader lamina, probably rounded at the ape.x. It is 
impossible to make out the structure in detail or to form any idea of the exact 
morphological nature of the scales. It is very probable, however, that the top of 
the specimen represents the lowermo.st portion of a cone. 
These specimens agree very closely with those described by Ward (1905, p. 133; 
pi. 36, figs. 3 — 8) under the name Sphenolepidiitin oregonense FONT., from the Jurassic 
of Oregon. The sterile branches figured by Ward cannot, for the most part, be 
distinguished from those shown in our pi. 9. The only difference seems to be that 
some of the North American specimens are slightly stouter; but a specific separation 
cannot well be made on that ground. The cone figured in Ward’s figs. 6 and 8 
resembles very much our specmien, fig. 13, pi. 9. In the latter the preservation is 
not very good, and nothing corresponding to the venation shown in the scales of 
the North American cone, can be observed; but otherwise there is a striking re- 
semblance. It is very probable that this resemblance is an indication of the identity 
of both structures. 
There seems thus to be fairly good evidence for regarding the Antarctic plant 
as identical with Sphenolepidiiun oregonense Font.; but it must be admitted that the 
latter species is not very well defined or well known. The branches are rather like 
some specimens of Sphenolepidiuni Kurrianum (so like, indeed, that a question of 
their specific identity might be raised), but the cone-like fragment does not afford 
sufficient evidence that the right place of the fossil is in the genus SpJienolepidmni. 
The identity of the Antarctic and the North American specimens, however, seems 
to be fairly certain.

PI. 9 , figs. 12 , 12 a. 
The small specimen shown in pi. 9, fig. 12, is possibly a portion of a cone and 
should in that case be recorded under the provisional name Conites. It consists of 
a short axis with some scale-like appendages attached to it at about a right angle. 
The apical portions of the scales are more or less strongly bent forward. The scales 
appear in a few cases to bear some body attached to their adaxial surface; their 
shape and structure cannot be made out, however. 
This specimen shows some resemblance to the cone-like fragment in fig. 13, pi. 9, 
referred to Sphe7iolepidiiim oregonense Font., but it is longer and does not look like 
a cone of Sphenolepidiuni. The material is too meagre to allow of any conclusions.
