A second and mucli enlarged edition of Prof. Feistmantel's 

 work is about to appear in English, published by the Government 

 Printer for the Geological Branch of the Department of Mines.* 

 From this I take the liberty of extracting the following remarks 

 of Dr. Feistmantel's in advance : — 



After again describing the fragment of Annularia australis as 

 only known to him, the author remarks that Prof. Schmalhausen 

 has described f a genus of Coniferous plants from the Jurassic 

 rocks of the Altai Mountains as Cydopitys, and like Annularia, 

 with the leaves arranged in whorls. Dr. Feistmantel adds : " In 

 a subsequent paper of his, Prof. Schmalhausen has brought my 

 Annularia australis into close relation with his genus Cydopitys. 

 I am, however, not qtiite certain about this correlation, especially 

 as I cannot remember having observed in the Australian speci- 

 mens a transverse striation to both sides of the midrib of the 

 leaflets, which Prof. Schmalhausen points out as a characteristic 

 of his genus." J 



The matter, therefore, stands thus : — We have on the one 

 hand a supposed Equisetaceous genus Annularia, in which the 

 leaflets simply bear a midrib without any transverse striation ; 

 and, on the other hand, a supposed Coniferous plant possessing 

 similar leaves which are transversely striated. Both species 

 described by Schmalhausen in the first of his quoted papers, viz., 

 Cydopitys Nordenskioldi, Heer, sp.,§ and C. Heeri, Schm., || show 

 the cross striation of the leaf very distinctly. These leaves seem
