Arauoaria (section Eidacta). In the absence of reproductive- 

 structures it is difficult to form an opinion as to the affinities of this 

 plant, but the striking similarity which the leaves and the form of 

 the branches of the fossil type bear to the recent Australian species 

 Arauoaria Cunninglmmii, Ait., leads me to favour the view of the 

 Arauoarian relationship of Bunbury's species. 



I have little doubt as to the specific identity of the specimens 

 named by Phillips Cryptomerites rigidus with C. divaricatus, Bunb. 

 This Conifer is represented by a very small number of specimens 

 in collections of Inferior Oolite plants ; the best specimens I have- 

 seen are Bunbury's type-specimen (Leckenby Collection) and a few 

 good examples in the Manchester Museum. 



Genus NAGEIOPSIS, Fontaine. 



[Potomac Flora, p. 194, 1889.] 



This generic name was chosen by Professor Fontaine for certain 

 vegetative shoots bearing a resemblance in the form of the leaves 

 to recent species of the genus Podocarpus, included in the section 

 JSFageia, in which the leaves possess numerous veins and not 

 a single midrib.^ As no reproductive organs have been found 

 in connection -with the vegetative shoots of Nageiopsis, the position 

 of the genus cannot be definitely fixed. "While admitting the 

 marked similarity between Fontaine's genus and certain species- 

 of Podocarpus, a comparison may also be made, as Nathorst has- 

 suggested, with the Australian Conifer Arauoaria Bidwillii, Hook.. 



Nageiopsis anglica, sp. nov. 



(Text-fig. 51.) 



Type-specimen. "Whitby Museum (2503). (Text-fig. 51.) 



Leaves distichous, attached to the short axis by a narrow base, 



broadly linear in form, from 1 to 1-5 cm. in length, traversed by 



several parallel veins, which converge slightly towards the leaf -base. 



This species is founded on some specimens in the "Whitby 



Museum which arc too fragmentary to admit of a satisfactory
