TJENIOPTERIS. 159 



Pieces of Nilssonia compta and Cladophlebis denticulata occur on 

 the same piece of rock. 



Scarborough. Bean Coll. 



V. 3670. A good example of a smaller frond. At the base 

 there is a short curved petiole similar to that of 39,217, but shorter, 

 and the frond tapers gradually to an acuminate apex. The venation 

 is well preserved. 



Gristhorpe Bay. 



8366. Lamina 15-5 cm. long, without the apex, 1-8 cm. broad. 

 The breadth is fairly uniform, decreasing gradually towards the 

 base and apex. 



Scarborough. Mantell Coll. 



10,327. Fragments showing clear venation; associated with 

 Saaenopteris Phillipsi, Cladophlebis lobifotia, Beania, etc. 



Gristhorpe Bay. Presented by Dr. Murray. 



13,501. An impression in ironstone of part of a large frond, 

 showing very clearly the forking of the secondary veins. Midway 

 between the broad midrib and the edge of the lamina there are 

 about seven veins to every 5 cm. of lamina ; close to the margin 

 the veins become much more numerous. 



Gristhorpe Bay. Presented by Dr. Murray. 



13,5020. A long and narrow frond similar to V. 3670.
