parallel course slii^htly oblique to the upper marc,n'n 

 throughout the great part of each pinna. 



The abundance of specimens of this form of Cycadean 

 frond in the museums of London, Manchester, Scarborough, 

 and elsewhere, enables us to recognise a considerable 

 range in the size and shape of the pinnae. There is 

 another specimen (No. 326) in the Manchester collection 

 which represents a somewhat different form of frond, also, 

 I believe, to be referred to Phillips' species. In some of 

 the specimens of Williauisonia pecten the base of the 

 pinnae shows no indication of any broadening or auricula- 

 tion ; but in the specimen shown in fig. 6 the upper margin 

 of base is slightly auriculate, and this character is still 

 more pronounced in the larger frond. No. 326. 



The Indian fronds, usually referred to a distinct genus, 

 PtilopJiylhivi, are, in many cases, I believe, generally 

 if not specifically identical with the English specimens. 

 I have arrived at this conclusion as the result of an exami- 

 nation of some specimens figured by Morris in a memoir 

 by Grant, " to illustrate a geological map of Cutch," and 

 now in the museum of the Geological Society, and by 

 comparing several other Indian specimens in the British 

 Museum with the Yorkshire coast fronds. Evidence in 

 support of this opinion will be more fully set forth in the 

 forthcoming British Museum Catalogue.
