THE MESOZOIC FLORA. 
67 
Of other Jurassic species with which the fronds here named 0 . Hislopi could 
be compared, it may suffice to mention 0 . latior Saporta (1875, p. 130, pis. 27, 
28). The resemblance is mainly in the habit, the latter species having a more mark- 
edly auriculate pinna-base than the present specimens.

The specimen shown in pi. 7, fig. 17, of which the counterpart is also in the 
collection, can with some accuracy be identified as belonging to the species first 
described by Oldha.M & Morris (/. c.) as Palæozainia Bengalensis Oldii. It is very 
fragmentary, but it shows well the characteristic habit of the species. The frond is 
very narrow and linear and has probably been of great length comparatively, since 
its two sides are quite parallel. The pinnæ are subopposite, attached at a wide angle. 
They are falcate, their distal edge being almost straight, the proximal very abruptly 
bent forward so that the pinna becomes almost rhomboidal in shape. The veins are 
given off from nearly the whole of the base, are faintly radiating, and bifurcating. 
The bases of the pinnæ are not well seen in the present specimen, but they appear 
to have been slightly auriculate. Fhe species is kept in the genus Otosaimtes mainly 
on the authority of ScHENK and Feistmantel. The latter author definitely placed 
the species in Otozamites and had to change the specific name of PaUeozamia benga- 
lensis. because the name Otozamites bengalensis had already been used by SCHIMPER 
for another species previously referred to Palæozamia. 
Although the generic character is not very well shown, there cannot be much 
doubt as to the specific identity of the Antarctic specimen with the Indian Oto- 
zamites abbreviattts. The former has the same peculiar habit and the same kind of 
venation as the latter. 
Otozamites abbreviattts has been regarded as an Eastern type of frond and has 
hitherto been found only in the Upper Gondwanas of India.

The small specimen shown in pi. 7, fig. 18, cannot well be identified with any 
known form, but it does not afford sufficient material for the creation of a new species.
