Ehaetic of Scania, another European Ehsetic species, Nilssonia 

 acuminata Goepp.,'''' and a Queensland fossil described by Shirley as 

 Ptcropliyllum quadriflorum. f 



Plate IV., figs. 1, 2 (291c). 



These fragments illustrate the characters referred to above. The 

 preservation is far from perfect, and it is possible that the reference 

 to Nilssonia is incorrect. In the lower right-hand segment of fig. 1 

 the lamina extends up to the middle of the rachis, and in this respect 

 agrees with species of Nilssonia. 



Other Specimens : 293c, part of a frond 8 cm. long. The lamina, 

 is much torn and broken, but there appear to be entire segments 

 broader than those represented in pi. iv., figs. 1, 2. The veins 

 are clearly preserved ; in the lower part of the specimen they spring 

 from the rachis approximately at right angles, in the apical region 

 being given off at a much smaller angle ; they are approximately 

 1 mm. apart, rather less numerous than in the specimens repre- 

 sented in figs. 1, 2, pi. iv. The lamina, at least in the apical 

 region, appears to be practically continuous over the axis of 

 the leaf. 



Also specimens of Araucarites scales. 



Genus CYCADOLEPIS Saporta. 



We owe this generic designation, to Saporta, J who made use of it 

 for fossils which he regarded as bud-scales of cycadean fronds. 

 In Part II. of the British Museum Catalogue of the Wealden 

 Flora § I extended this term to include " Scale-like leaf structures 

 of cycadean plants, varying considerably in form and including 

 detached petiolar bases, bud-scales, &c., also isolated carpellary 

 or antheriferous scales which exhibit no trace of ovules or pollen- 

 sacs." 



We might add to this designation, scale-like structures which may 

 have served as a protective covering to young and unexpanded 

 vegetative leaves or fertile shoots.
