woody axis with lateral wings, and gives off spreading pinnae bearing 

 slender linear segments the lamina of which is divided into acuminate 

 teeth. 



Other Specimens : 433c. — This specimen shows very clearly the 

 narrow pinnae with entire segments (c/. tig. 3) in the apical region of 

 the frond; also the gradual transition from the narrow oval segments 

 to larger segments w^ith a serrate margin. 140c, 320c (on the reverse 

 side is a good impression of a Cycaclolepis jenkinsiana), 389c, 390c 

 (with seeds of Araucarites rogersi), 392c, 411c, 429c, 430c. 



Genus CLADOPHLEBIS Brongniart. 



(Of doubtful Family-position.) 



Brongniart proposed this generic name in 1849 "■■ for certain forms 

 of Pecopteris, previously included in the group Neuropterides. The 

 genus is founded on sterile fronds only, and is applied to ferns which 

 cannot be referred to a particular family ; the name Cladophlebis is 

 usually made use of for Mesozoic species which agree in habit with 

 Palaeozoic representatives of Pecopteris. Numerous fossil ferns have 

 been described by authors as species of Aspidium, which, in the 

 absence of sori or sporangia, have no claim to be designated by the 

 name of a recent genus.
