Genus — C Y CLOPTERIS, Brongniart. 
Obs. — Some fragmentary specimens only arc placed with this genus. 
Cyclopteris cuneata, Carruthers.

Sp. Char . — Fronde tota ignota ; pinnis integris, magnis, cuneatis, hasi 
angustatis, margine externo rotundato; nervis tenuibus, semel bisque dicho- 
tomis, liinc illine media in pinnula anastomosantibus. 
“ Form of the entire frond unknown ; pinnae entire, large, cuneate, 
narrowed at the base, with tlie distal margins rounded ; veins delicate, once 
or twice dicliotomously divided, sometimes anastomosing once in their length 
in the middle of the pinnae.” 
Obs. — Mr. Tenison Woods, after having examined the type specimen 
which is preserved in the Brisbane Museum, concurs with me in my opinion 
that this is not a complete frond or leaflet, but a wedge-shaped fragment 
broken oh by chance. 
The anastomosis of the veins, if even only partial, docs, perhaps, 
indicate that the species is not a true Cyclopteris in Brongniart’s sense. 
Locality and Horizon. — At the Tivoli Coal Mine, Ipswich, Queensland 
(Upper Mesozoic). 
Genus — ALETIIOPTERIS, Sternberg. 
Obs. — The old genus, Alethopteris, lias been found to contain various 
types of fossils, viz., those of the Palaeozoic formations, which remain 
with this genus, and Mesozoic forms, some of which have been found in the 
fructifying state, and which are now placed in the Asplenieae with the chief 
genus Asplenium ; such species are — Asplenites Bdsscrti, Presl, sp. ; Alethop- 
teris nebbensis, Bgt. ; A. Heeri, Natli.; A. whitby ensis , Bgt. ; A. dentata, 
Bgt. ; A. Bhillipsi, Bgt.; A. indica, Oldh., and others. 
In Australia it appears that at least one species belongs to this group. '
