the racliis, up to 2-3 cm. long and 3 to 4 mm. broad, parallel-sided, 

 with the apex bluntly rounded ; they are attached laterally (?) by 

 the whole base and are traversed by a small number of veins which' 

 divide dichotomously once near the rachis ; there are up to about 

 10 veins in a single pinna. 



The specimens described here are similar in general form to 

 Pterophyllum contiguum, Schenk, as figured by Fontaine, 2'' and also 

 to Zeiller's description of P. contiguumP-^ from the Rhaetic of Tonkin.

Frond broad, long, becoming narrower towards base and 

 apex, the pinnae being up to about 4 cm. long in the central part 

 and 2 cm. at the lower end. The rachis is strong, being up to 3 mm. 

 in breadth, and is finely striated. The pinnae are at right angles 

 to the rachis, alternate or subopposite, linear, up to 1 cm. wide, with 

 bluntly rounded apices ; they are attached laterally by the whole 

 base, adjacent pinnae being joined by slight ex^^ansions. The veins 

 are fine, parallel to the edge, dichotomous and numerous, there 

 being about 18 at the base of the pinnae and 30 to 36 near the outer 

 end. The largest frond available is about 18 cm. long and when 

 complete was probably more than 20 cm. in length. 



The specimen named by Shirley ^^ as P. yerongense is only a 

 fragment showing the rachis and the basal portions of a few pinnae, 

 and there is little doubt of it being a portion of a large frond of
