Pis. c, ci. Sphenopteris crenata, L. and H. 



SCHIZOPTERIS ADNASCENS, L. and H. 



Locality. — Whitehaven Coal Field. 



Horizon. — Coal- Measures. 



Bemarks. — That the Schizopteris adnascens is an integral 

 part of Sphenopteris crenata is beyond all doubt. The type 

 specimen is in the museum at Newcastle. 



I defer any further remarks on this species, awaiting the 

 examination of certain specimens at present in my possession. 



PL cvii. Pecopteris serra, L. and H. 



Locality. — Whitehaven Coal Field. 



Horizon. — Coal-Measures. 



Remarks. — The tg^pe of this plant appears to be lost. From 

 the figure and description, it is difficult to form a correct idea 

 of the characters of the species. It is probable that it is not 

 specifically distinct from Dactylotheca plumosa, Artis sp. 



PI. Cviii. ASTEROPHYLLITES COMOSUS, L. and H. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. 



Remarks. — The type is preserved in the " Hutton Collec- 

 tion." It is too imperfect for any accurate determination. 

 The plate is very much more distinct than the specimen in 

 its present condition. 



PL cix. Sphenopteris obovata, L. and H. 



Locality. — Newcastle Coal Field (?). 



Remarks. — The above locality is given by Lindley and 

 Hutton for this species, which was communicated to them 

 by T. Allan, Esq., Lauriston Castle, Edinburgh. I believe 

 this species is the same as their Sp)henopteris excelsa.'^ From 

 the fact that the specimen came from Mr Allan, Edinburgh, 

 and that the matrix of the type in the " Hutton Collection " 

 and the plant itself is similar to specimens occurring at 

 Granton, near Edinburgh (Calciferous Sandstone Series), I 

 have no doubt there is an error in the locality given for this 

 specimen.
