Remarks. —The genus Chiropteris is a somewhat rare type, only known at present 
from Rhsetic rocks in various parts of the world. C. digitata Bronn(l), a much 
larger leaf, occurs in Europe, C. cuneata Carr.(2) in Australia and South Africa(3), 
C. copiapensis Solms(4) in South America, and C. Zeilleri Seward(5) in South Africa. 
The specimen from South Australia described under the name Anthrophyopsis (?) sp. 
by Etheridge(6) in 1895 is also a member of this genus, and may be distinguished 
as Chiropteris Etheridgei sp. nov. 
Type in the British Museum (Natural History). 
Occurrence. —Mount Potts (Rhsetic).

Diagnosis. —-The following diagnosis was given by Seward in 1894 (see above) : 
“ Frond bipinnate, rachis fiat and broad, pinnae linear-lanceolate, alternate to opposite, 
pinnules falcate, contiguous, attached by the whole of the broad base, acuminate, 
margin entire or slightly dentate towards the apex.” 
Description of the Specimens. —Two examples of fronds from Waikato Heads, 
with small, triangular, somewhat falcate pinnules, are shown in Plate IV, figs. 2 and 3, 
natural size. In the larger, fig. 2, several pinnae are seen attached to a slender 
axis. These vary from 1 cm. to 4 cm. in length, and the pinnules are about 7 mm. 
long. The nervation is obscure, but appears to be of the Cladophlebis type. 
Remarks. —It may be doubted whether these specimens are sufficiently perfect 
to allow of specific determination. They appear to lie nearest to Cladophlebis Albertsi 
(Dunk.), to which perhaps they may be doubtfully referred. 
Occurrence. —Waikato Heads, Auckland (Neocomian).
