which come so near the Antarctic species as the Franconian specimens just men- 
tioned, not even the English 0 . obtusus (Lindl. «S: Hutt.), which has a more rounded 
proximal edge of the pinnæ. 
There is one more species of Otozamites, viz. the Liassic 0 . gracilis (KuRR) 
(1846, p. II ; pi. I, fig. 4) with which 0 . linearis can be compared. The resem- 
blance is not so much with the type-specimen as with some fronds referred to the 
same species by Salfell.) (1907, p. 183; pi. 19, figs. 2 — 7; pi. 20, figs, i, 2). The 
specimens shown in his pi. 19, figs. 2 and 3, present a very great resemblance in 
habit to the frond in our text-fig. 15, especially in regard to the great length and 
linear shape of the frond and the distant position of the pinnæ. Even the shape of 
the latter is somewhat similar, but the anterior basal lobes are much less developed 
than in the Antarctic species. The other specimens of Salfeld’s differ much more 
from our species, in the same degree as they resemble Kurr’s type-specimen; and on 
the whole there can hardly be any question of specific identity with Kurr’s species. 
Finally Otozamites indosinensis Zeiller (1903. p. 168; pi. 43, fig. i) from 
Tonkin may be mentioned as presenting some resemblance to the smaller specimens 
of 0 . linearis. It differs, however, from most of our specimens in having broader 
pinnæ with smaller auriculate lobes, and is probably not identical with the Antarctic 
species.

In pl. 7, fig. 6, is shown a. specimen of an Otozamites wdiich is best referred 
to the Rhætic species O. latior S.VP. 
The specimen represents the lower part of a rather large frond. The pinnæ are 
inserted on the upper side of the rachis with a very oblique base, and the opposite 
ones overlap very markedly. The base is auriculate but not so much as in the 
two species Filicites Biicklamlii or F. Bechii (IJkongni.art, 1S24, p. 422: pl. 19, figs. 3. 4). Zeiller (/. cl) 
has clearly shown that the form from the Oolite of France should be named Otozamites Bechii (Brgn.), and 
he considers the English O. obtusus (Lindl. & Huit.) as identical with it. Of Brongni.art’s two varieties 
of Filicites Bucklandi, the figure of the type-specimen of B gallica, from the Oolite of France, hardly per- 
mits of any opinion; the variety a brita?znica from the English Lias should, I think, rather be identified 
with Otozamites graphicus (Bean) (Leckenby 1864, p. 78, pl. 8, fig. 5), which has been suggested as an 
alternative by Zeiller (/, c.). According to these considerations, and if the identification of O. brevifolius 
(Braun) with O. obtusits (Lindl. & Hutt.) is right, the Franconian specimens, with which the .Antarctic 
form has been compared, should be referred to 0 . Bechei Brgn. The identity of the Franconian species 
with 0 . Bechei had indeed been asserted already by Schenk (/. c.. p. 139).
