Lane cfV Saunders: Fossil Plants from Marske, etc. 



Several years ago, the late Rev. J. Hawell did some excellent 

 pioneer work in the Marske quarry, which resulted in the 

 identification of seventeen species. He also found a Dictyo- 

 zamites for the first time in England, which proved to be a new 

 species, and was named Didyozaniites haivelli. 



The following is a list of plants found by us since September 

 1908, duplicates having been given to the Hull and Middles- 

 borough Museums. Many of these specimens have been sub- 

 mitted to Prof. Seward for diagnosis. We also wish to acknow- 

 ledge the valuable assistance of Mr. Elgee of the Middles- 

 brough Museum, who has given us access to plants previously 

 determined, and helped us in our determinations.

We have other specimens in our possession pending deter- 

 mination. Further finds will be reported from time to time in 

 ^ The Naturalist.' We note that Olozamites beani occurs in 

 Upleatham quarry, but is very scarce in Marske ; Teniopteris 

 vittata is found in larger specimens in Upleatham ; Nihonia 

 ■compta is plentiful in the central part of Marske quarry ; Dic- 

 tyozamites is extremely rare. On much the same geological 

 horizon near Carlton, Mr. Lane found recently two new species 

 which Prof. Seward determined as follows : 



Zamites sp., resembles Z. buchianus (Wealden Flora). 



Zamites sp., probably new. 

 ^^'e feel convinced that further effort will be successful.
