168 SAGENOPTERIS. 



there are four leaflets, shorter and broader than those in 39,222 

 (Text-fig. 24), borne on a common petiole ; each leaflet is about 

 4'5 cm. long and 1*6 cm. broad, with a distinct midrib and long 

 narrow meshes formed by the secondary veins. This type of 

 leaf forms a more or less intermediate form between the long 

 and narrow type shown in Text -fig. 24 and the large segment 

 represented in Text - fig. 26. There is a striking resemblance 

 between this specimen and some of the figures of Sagenopteris 

 rhoifolia as published by Schenk ; it emphasizes the very close

 indeed can hardly be separated by any satisfactory characteristics.

The original of this figure is in the Scarborough Museum ; 

 there is a similar but rather smaller example in the British 

 Museum Collection, No. 40,468, but a still longer specimen occurs 

 in the Manchester Museum, 1 measuring about 1 1 cm. long ; the 

 figured specimen measures 8-5 cm. in length and 2 cm. in breadth. 

 There is a close agreement between this leaflet and those of
