the lamina. Some of the others are a little broader than is generally the case in 
this species, and the question might be raised whether those seen in figs, i and 3 
should not be referred to S. Nilssoniana (Brgn.). Especially the undulation 
of the margin in the former of these specimens is very suggestive of a charac- 
teristic feature in S'. Nilssoniana. Some of the specimens previously referred to S. 
Phillipsii, however, have leaflets of about the same breadth; so, for instance, one 
figured by Lindley & Hutton (1833, pi. 63, fig. i) and refigured by Seward 
(1900, p. 168, fig. 25). As has been remarked by several authors, especially by 
Seward, it is in many cases impossible to distinguish between the two species in 
question. Since S', pancifolia is represented by some typical specimens whereas S. 
Nilssoniana is not, it seems better to refer these questionable specimens also to the 
former species. 
Sagenopteris pancifolia is one of the more common species of Jurassic plants. 
It has been recorded from different areas in Europe, and from North America. 
Feistmantel (1878, p. in; pi. 15, fig. 10; — 1890, p. 135; pi. 29, fig. 6) has de- 
scribed from Tasmania a Sagenopteris which he names N. (?) tasnianica. It is pos- 
sible that this species is identical with A pancifolia, which would in that case al- 
ready be known from the Southern Hemisphere; but Feistmantel’s material is 
much too poor to allow of any decision. The form described from Queensland as 
Sagenopteris cnneata (Shirley 1898, p. 24; pi. 23) was originally so named 
(= Cyclopteris cnneata Carruthers in: Daintree 1872, p. 355; pi. 27, fig. 5) in- 
dependently of the English S. cnneata (Lindl. & Hutt.) which I believe Bunbury 
and Seward are right in referring to A pancifolia. S. cnneata Shirley should 
no doubt disappear altogether. Whereas A pancifolia is thus not with certainty 
found in Australia, S. Nilssoniana was recorded from that continent, in typical spe- 
cimens, by Feistmantel in 1879. 
Genus Dictyophyllnm Lindley & Hutton. 
Dictyophyllum sp. 
PI. I, figs. 28, 28 a\ text-fig. 2. 
In pi. I, fig. 28, is figured a fragment of a leaf showing reticulate venation. 
Although very small and not very distinct, it looks rather like a portion of a frond 
of Dictyophyllnm. After the plate was already printed, there was discovered in the 
same piece of rock another likewise fragmentary specimen which places the occur- 
rence of the genus in the Hope Bay flora beyond doubt. This specimen is shown 
in text-fig. 2.
