PL Ixxxvii. Cakpolithes alata, L. and H. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. 



Benfiarks. — The Carpolithes alata, L. and H., is the 

 Teigonocarpus Parkinsoni, Brongt., enclosed in its peri- 

 carp. I have seen several specimens revealing this very 

 clearly. 



PI xc. Cycloptekis OBLiQUA, L. and H. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. 



Remarks. — 'These large cyclopteroid pinnules were borne 

 on the rachis of several species of Neuropteris, but from the 

 figures here given it is impossible to determine the species 

 to which they belong. They may possibly be referable to 

 Neuroptepjs heterophylla, Brongt. 



PI. xcic&. Neuropteris ingens, L. and H. 



Locality. — Jarrow Colliery. 

 Horizon. — Lower Coal-Measures. 



Remarks. — This species of Neuro'pteris is too ill defined to 

 enable me to identify the plant indicated. 



PL xci&. Cyclopteris dilatata, L. and H. 



Locality. — Felling Colliery, near Newcastle. 



Horizon. — Lower Coal-Measures. 



Remarks. — This is another Neuropteroid pinnule. The 

 nervation is not sufficiently indicated to determine the 

 species. I believe, however, that it is referable to Neurop- 

 teris heterophylla, Brongt. 



PL xciv. Pecopteris nervosa. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. Shale from the Bensham 

 Seam. 



Remarks. — This is now regarded as a variety of Mariopteris 

 {Pecopteris) muricata, SchL, and classed as Mariopteris 

 MURiCATA, SchL sp., var. nervosa.
