RAVENHEAD COLLECTION IN THE BROWN FREE LIBRARY AND MUSEUM. 409 



Remarks. — This species is only represented by a single pinnule, but it agrees so 

 completely with Lesqueeeux's description and figure that I have no doubt that the 

 Eavenhead specimen is identical with Lesqueeeux's species. 



Neuropteris dentata is one of a group of Neuropterids whose pinnules have dentate 

 or ciliate margins, and whose relationship to each other is not yet clearly made out. They 

 usually occur in a very fragmentary condition. 



In my paper on the Fossil Flora of the Radstock Series, I have given three figures of 

 what I believe to be the Neuropteris Jimbriata, Lesqx.* 



Heee describes two species which are very closely related to these, viz., Neuropteris 

 (Cychpteris) lacerata and Neuropteris (Cyclopteris) ciliata,f which perhaps should be 

 referred to one or other of the American species.
