his observation of two closjly disposed nerves instead of one, thus 

 establishing the new genus Pseiidocycas. The representatives of the

The genus Glossozamites is a typical representative of the 

 Wealden and Lower Cretaceous, but has not yet been found in the 

 Cenomanian. G. Schenkii from Kome differs from G. HoJieneggeri^^ 

 Schenk by having broader segments and more numerous and richly 

 forking veins, but shows a close resemblance to our species. G. 

 HoJicneggeri, figured by Prof. Yokoyama'^ from the Cretaceous of 

 China, is identical with its original type and thus essentially differs 

 from our specimens. The lack of material prevents our making 

 any more detailed comparison.
