Lane c5^' 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- 

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

 species, and was named Dictyozamites hawelli. 



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

 igo8, 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 Otozamites heani occurs in 

 Upleatham quarry, but is very scarce in 'Marske ; Teniopteris 

 vittata is found in larger specimens in Upleatham ; Nilsonia 

 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 

 Avhich Prof. Seward determined as follows : 



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



Zamites sp., probably new. 

 We feel convinced that further effort will be successful.
