CLABOPHLEBISi 145 



The slender rachis gives oS opposite and sub-opposite pinnte 

 ■with, short, broad, and apparently entire segments. It is not 

 improbable that this example may be regarded as the apex of 

 C. dentieulata. The veins are exceedinglj- well shown. Cf. 

 specimen 39,240 (PI. XV. Fig. 5). 



It is just possible that this specimen and 39,240 (PI. XV. 

 Fig. 5), both of which have pinnules with entire margins, belong 

 to a separate species of the type represented by P. wMtbiensis, as 

 figured by Lindley & Hutton ; but we have not, I think, sufficient 

 evidence to justify a specific separation of these two specimens 

 from Gladophlebii dentieulata.

Other specimens : — V. 376. Fragment of the apical portion 

 of a fi-ond similar to 39,248 (PL XV. Fig. 4), but rather less ; 

 too small to be determined. V. 3900. A small indeterminable 

 fragment — possibly Cladophlehis, sp. — in white sandstone, two miles 

 south of Ravenscar, on the Yorkshire coast. The following are 

 undoubted examples of C. dentieulata: 10,368, 39,235, 39,277, 

 40,517 (a very fine pinna with long falcate pinnules 3*7 cm. long), 

 40,559, 52,568 (fertile pinna). 



B. Ferns lohich afford no trustworthy evidence as to their 

 affinities with existing families.
