Mesozoic forms, especially Triassic, which lie calls Neuropteridium. I have 
myself seen no Neuropteris from Australia, but the Rev. Tenison Woods 
describes one species, which, however, might rather be placed with Neurop- 
teridium, as it has a single pinnate frond, and, besides, appears to come from 
Mesozoic strata. 
Neuropteris (? Neuropteridium) australis, Ten . Woods. 
Ncuropteris australis, Tenison Woods, loc. cit., 1883, p. 100, PI. 8, figs. 4, 5. 
Sp. Char. — “ Frond pinnate, with a thick, broad, conspicuously grooved 
rachis ; pinnae ovate and lingulate, the lower ones moderately and irregu- 
larly' dobed and obtuse, unsymmetrical, the upper ones ovate, acumiuatc with 
an acute apex, the apical pinnules trifoliate, with lobes broadly rounded, and 
affixed to the rachis Try a somewhat broad petiole ; veins rather thick and 
prominent, radiating from the base, the venules running almost parallel in a 
curve to the margin ; length of lower pinnules 15 to 20 mm., breadth 8 to 10 
mm., upper ones gradually diminishing in length and breadth to the summit 
of the frond.” 
Ohs. — The figured specimen is not very complete, so that it is not 
easy to compare it with other known forms ; but, as already mentioned 
above, it would really appear to be of the type of Neuropteridium. 
Locality and Horizon. — Mr. Tenison Woods says that the specimen 
was found in the gravel of the Bell River, near Wellington, New South 
Wales, in an ironstone which was evidently derived from some of the 
limonite nodules such as arc obtained from the Hawkesbury beds ; the 
formation is thus not quite certain.

Ohs. — In this genus I placed originally a species of fern, which is 
frequent enough in Australia and Tasmania, and which was variously 
described as Tccopteris or Odontopteris. As regards the position of this 
genus, it is placed by Schimpcr (Ilandbuch der Palceontologie, p. 123) in the 
group of Lomatopteridese, together with Lomatopteris and Cycadopteris.
