Fig. 4. — Asplenium raritanense Berry. Hylton Pits, Pensauken Creek. 



This species, which is quite unHke anything heretofore known 

 from the Raritan, is unfortunately based on the single tiny 

 pinnule figured. The general form and habit remain unknown. 

 It is markedly distinct from any described fossil species known 

 to the writer, although showing some points of resemblance to 

 various arctic species referred to this genus by Professor Heer. 

 Since the chances of more representative material being found 

 are remote, it has seemed best to describe it under the above 

 name. 



Occurrence. — Hylton Pits. 



Collcctioti. — Johns Hopkins University. 



ASPI,ENIUM JERSEYENSIS Sp. nOV. 



Description. — Frond compound (?). Pinnse linear in outline, 

 made up of alternate triangular somewhat falcate pinnules. The 

 latter have acute tips and entire margins ; they are attached by 

 their entire base. Rachis very stout. Texture extremely thick 

 and coriaceous. ■ . 



Midrib stout, branching from the rachis in the proximal half 

 of the pinnule, giving off alternate, apparently forked secondaries 

 on either side. 



This species is based upon the incomplete specimen figured 

 and its counterpart. In appearance it is exactly like so many 

 Cretaceous fern-fragments which are referred to the genus 

 Gleichenia, as for example Gleichenia gracilis Heer or Gleichniia 

 acutiloba Heer, it being particularly close to the Bohemian re-
