 odontopteroides Morris, in the Leigh Creek Goal 

 Measures. (Gontributions to the Palaeontology of South 

 Australia. 1902. No. 12. p. 2. plate I.) 



A description of the characters of the most complete 

 specimens which have so far been obtained from this locality 

 in South Australia. The nervation is here more complex 

 than is generally met with in Australian specimens of this 

 species, and does not represent the typical form of T. odon- 

 topteroides. It is pointed out that three, if not more, varieties 

 of nervation have been included at various times in Thinnfeldia,. 

 and that this nervation seems to oscillate between that of the 

 genera Thinnfeldia, Odontopteris and Lescuropteris.

From the Dawson River^ Anthracitic (B) Series, 

 (Permo-Garboniferous) Noeggerathia ? several species of Sphe- 

 nopteris and Glossopteris are recorded, and also a new seed 

 Cycadospermum Dawsoni. Sphenopteris lolifolia Morr. is 

 referred to the genus Mertensia on the discovery of the fructi- 

 fication. The sori are in masses on the first fork of the 

 primary veins of each pinnule, there being one sorus for each 

 lobe, and, as in Gleichenia, their modern allies, the margins
