It is, however, hardly possible, at least in some cases, to dis- 

 tinguish between the species Oladophlebis browniana and Klulcia 

 ewilis (PhilL). 



Prof. Zeiller 1 has recently recorded the occurrence of fertile 

 pinnae of a fern from the Wealden of Peru, which he regards as 

 closely allied to Pecopteris browniana ; and a fern from the same 

 country figured by Dr. Salfeld 2 as Oladophlebis sp., cf. Coniopteris 

 arguta Lind. & Hutt., appears to be identical with CI. browniana. 

 The same remark is applicable to this author's Filicites (lAletho- 

 pieris) ellensis. 



It is interesting, in view of the close agreement between Klulcia 

 exilis 3 and 01. browniana, to find that Prof. Zeiller speaks of the 

 fertile pinnae of his Peruvian fern as possessing ovoid sporangia of 

 the Schizasaceous type.

This species is represented by a clearly-defined impression, in 

 which the ultimate segments are a little larger than in most of 

 the previously recorded examples, but slightly smaller than the 

 pinnules of specimens referred to Onychiopsis elongata (Geyl.) in 

 Part I of the ' Wealden Flora.' 



The American authors Ward i and Berry 5 have adopted for this 

 species the name Onychiopsis psilotoides (Stokes & AVebb) ; but, in 

 view of the long usage of the designation mantelli and the frag- 

 mentary nature of the fossil figured by Stokes & Webb, I retain 

 the more familiar name. A re-examination of the English material 

 led me to regard the forms previously assigned to the two species 

 0. mantelli and 0. elongata as one species. Mr. Berry has, however, 

 examined some of the Japanese fossils described by Dr. Tokoyama 

 as 0. elongata, and his view is that they are not specifically identical 

 with the Potomac plant referred to 0. psilotoides. This author 

 includes 0. elongata in his synonymy of 0. goepperti (Schenk).
