144 PHYLLOPTERIS 
almost identical. A similar form of leaflet has been described by 
Dr. H. Woodward! from Mount Adams in South Australia, but the 
original specimen of the figure which he gives is an imperfectly 
preserved impression on sandstone, and shows no venation except 
an indication of a midrib; the clearly cut and numerous lateral 
lines of the woodcut are evidently the engraver’s vein-like 
shading. Compare also the fragments referred by Newberry to 
the genus Chiropteris from the Kootanie beds of Montana.? 
From such specimens as occur in the National Collection it is 
impossible to arrive at any satisfactory conclusion as to the real 
nature of the species. The name assigned to it is rather for 
purposes of convenient reference than intended to convey the 
idea of a well-defined specific type. 
V. 2816. Pl. IX. Fig. 6. 
A single leaflet with an apparently truncated apex, due no 
doubt to tearing. Veins fairly distinct as black curving lines on 
the brown impression of the lamina. No signs of reticulation 
noticed. Length 3 cm., somewhat ovate-lanceolate in form. On 
the same piece of rock is a fragment of what appears to be the 
short stalk of a leaflet. This specimen comes very near to Chiro- 
pteris spatulata, Newb.,? from the Kootanie group of Montana.

V. 2344. Probably the same species, in spite of certain differences 
in size and shape. The venation is of the same Phyllopteris 
type; in this specimen the apical part is preserved and shows the 
lanceolate termination of the leaflet. Cf Nathorst, pl. xix. fig. 2,
