Introduction. 



Mr. John Mitchell, of Waratah, recently forwarded me a large 

 number of fossil plants from New South Wales for determination 

 and description. Amongst them is a small collection of some 

 thirty-five specimens from Bexhill, 6 miles from Lismore along 

 the Lismore-Murwillumbah railway line, and these are described 

 in the present paper. I have to exj^ress my indebtedness to Mi'. 

 Mitchell for his kindness in giving me the opportunity of ex- 

 amining his collections. 



The specimens undoubtedly come from portion of the Clarence 

 Series, and as the number of plant species recorded from this 

 Sei'ies is very small, and also as there is not yet complete agree- 

 ment as to the subdivision and exact correlation of the Series, 

 the present collection is of more than passing interest. 



There is no need to go into the history of the classification of 

 the Clarence Series here; Carne has already discussed it at some 

 length.* Suffice it to say that previous to Mr. Carne's examina- 

 tion, it was divided into Lower, Middle, and Upper Clarence 

 Scries, the Middle Series being of rather solid, massive sand- 

 stones. Mr. Carne, however, reported that he could see no 

 reason for retaining this subdivision, and in the latest geological 

 map of New South Wales the Series is not subdivided, and it is 

 at present regarded as ecpiivalent to the Artesian Series in New- 

 Smith Wales, and the Walloon Series in Queensland. There is 

 certainly a massive, barren sandstone of considerable thickness
