THE MESOZOIC FLORA. 
65 
specimens of the preceding species figured in figs, i — 4 of the same plate. The 
pinnæ taper gradually from the base to the apex, which is narrow and pointed. 
The edges are nearly straight, especially the proximal one, so that the lamina be- 
comes ensiform. The venation, which is fairly distinct, is more parallel than in the 
preceding species. 
This form agrees in all respects with typical specimens of 0. latior Sap. 0. 
latioi' was instituted by Saporta for the large and broad specimens referred by 
SCPIIMPER and Schenk (//. c.) to Otozainites Biicklandi. In the opinion of the 
present writer the species is indeed better kept separate from the forms commonly 
referred to O. Bucklandi [or more correctly O. Bechei (see p. 63 , note)]. If SCHENK’S 
0. Bucklandi is, as usual, considered identical with 0. obtusus (Lindl. & HuTT.), 
the fronds of the type of 0. latior cannot well be included in the same species, as 
this would then be impossible to define, 0. latior differing from 0. obtusus in rather 
important points. The pinnæ of O. latior are much narrower than in the latter spe- 
cies, and taper, with nearly straight edges, gradually to the apex, which is much 
more elongated and pointed. 
Everything considered, it is not possible to point to any differences between 
the specimen in pi. 7, fig. 6, and O. latior SAP., except that the former is a little 
smaller than most of the specimens referred to that species. On account of this re- 
semblance the Antarctic frond has been referred to 0. latior in spite of the differ- 
ence in geological age. A similar difference exists between the species named here 
0. linearis and the specimens of Schenk’s O. Bucklandi^ but in the case of 0. la- 
tior no specific difference can be found, and so there is no other way than to refer 
the Antarctic specimen to the Rhætic species.

To the Indian species Otozauiites Hislopi (Oldh.) are referred here with some 
hesitation a few specimens, of which the best are seen in pi. 7 , fig. 5 . This figure 
shows fairly large portions of three fronds and small fragments of a fourth. The 
arrangement of the fronds in the rock is such as to suggest the probability of their 
origin from the same stem. Fig. 7 in the same plate represents the basal part of 
another specimen which is somewhat different but probably belongs to the same 
species. The description given here refers mainly to the specimen in fig. 5>
