bluntly rounded ai)cx, and gradually tapering towards the 

 base. There is a fairly distinct midrib, which gradually 

 breaks up in the apical portion of the lamina into 

 oblique anastomosing veins. The lateral veins are of the 

 Glossoptcris type, and frequently anastomose with one 

 another as they pass upwards and outwards towards the 

 margin of the lamina. In the later edition of Pliillips' 

 Geology of the Yorkshire Coast, and in the more recent 

 notes by Nathorst on Jurassic plants from English 

 localities, there is a reference' to a large form of Sage- 

 nopteris represented in the Leckenby collection and else- 

 where, which agrees closely with the plant described by 

 Zigno as Sagenoptcris Goeppertiana. The example shown in 

 fig. 8 is one of the best specimens I have seen of this large 

 type of leaf ; it is considerably larger than the type-speci- 

 mens of S. Pliillipsi of Lindley and Hutton,but examples 

 are not wanting which enable us to construct a series 

 illustrating the gradual passage from smaller and narrower 

 to larger and broader leaves. It is, I believe, the better 

 plan to regard such specimens as that shown in fig. 8 as 

 specifically identical with the more typical examples of 

 Sagoiopteris Plnllipsi, and to refer to them as 6". Phillipsi 

 var. major.
