the form of the leaf-scars indistinct. The specimen is un- 

 worthy of specific rank, not possessing the necessary 

 characters. 



PL ccvi. Lepidodendron oocephalqm, L. and H. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. 



Rer}iarhs. — The type of this species is not in the collection, 

 but being, as stated by the authors, " apparently the fructifi- 

 cation in an incipient state," the retention of the specific 

 name for this fossil can serve no practical purpose. 



PL ccvii. Lepidodendron plumarium, L. and H. 

 Locality. — Jarrow Colliery. 

 Horizon. — Lower Coal-Measures. 



Bemarlis. — I have little doubt that this species is founded 

 on a leafy branch of Lepidodendron ophiurus, Brongt. 



PL CCX&. Carpolitiies alata, L. and H. 



Locality. — Jarrow Colliery. 

 Horizon. — Lower Coal-Measures. 

 Remarks. — See notes under pi. IxxxviL 



PL CCxi. ASTEROPHYLLITES RIGIDA. 



Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. 



Remarks. — The original specimen is apparently lost, and 

 the plate being admittedly inaccurate, no satisfactory position 

 can be assigned to the plant. Making the deductions from 

 the drawing indicated by the authors, it may possibly be the 

 Calamoeladus equisetiformis, Schl. sp. 



PL ccxii. Sphenopteris excelsa, L. and H. 



Locality. — Newcastle Coal Field (?). 



Remarks. — This may perhaps be identical to their 

 Sphenopteris ohovata, but on this point I do not speak 

 positively. 



It is extremely probable that their type came from the 

 Calciferous Sandstone Series of the neighbourhood of Edin-
