Cardiopteris tasmanicus. (Nov. sp. Fig. 9.) 



Frond reniform-cordate, deeply auricled. Nerves numerous, 

 distinct, although somewhat immersed in a coriaceous mem- 

 brane, and radiating from base attachment to margin regu- 

 larly, arcuately, and dichotomously. 



With the exception that it is more symmetrically rotund 

 and more deeply auricled, it comes close to Cardiopteris 

 frondosa (Goe p.), Schimper. 



Greatest length, ff- inch. Greatest breadth, |--f inch. 



Locality. — Altered Upper Mesozoic coal measure shales, 

 near East Bay Neck, Tasman Peninsula, Tasmania. 



Collected by the Rev. J. Button, Dunally.

Shales. 



The greater part of the shales forwarded to me by the 

 Eev. J. Bufton are much broken and friable, and the impres- 

 sions are either obscure or very fragmentary. From a careful 

 examination of these, however, I have, in addition to the 

 forms already described, considerable confidence in referring 

 a number of them to the following genera and species : — 

 Macrvtieniopteris wianamattce ? Fstm. 

 Gleichenia dubia. Fstm. (Fig, 17.) 

 Trichomanides spinifolium. T. Woods. 

 Neuropteris tasnianiensis ? E. M. Johnston. (Fig. 1.) 

 Ptilophyllurn oligoneurum. T. Woods. 

 Pterophyllum. Sp.
