Palceozoic Sjjecies mentioned in ''Fossil Flora." 36 



Q 



PI. Ixxi. SrOILLARTA RENIFORMIS. 

 Locality. — (?) 



Remarhs. — This is another decorticated specimen of Hvjil- 

 laria, which cannot be specifically determined. 



PL Ixxii. SiGILLARIA (?) MONOSTIGMA, L. and H. 



Locality. — Sandstone Quarry, Cramlington, Northumber- 

 land. 



ILorizon. — Lower Coal-Measures. 



Remarks. — This is a single isolated rib of a Sigillaria in a 

 decorticated condition. 



Pis. Ixxiii.-lxxv. Favulaeia tessellata. 



Locality (pis. Ixxiii., Ixxiv.). — Ov^erlying Coal Strata, at 

 Garthen Colliery, near Euabon, Denbighshire. 



Locality (pi. Ixxv.). — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. Bensham Seam. 



Remarks. — Not having seen the originals of these plates, 

 it is difficult to express any opinion on them. It is probable 

 that the specimens represented on plates Ixxiii. and Ixxiv. 

 are the Sigillaria tessellata, Brongt. I have, however, 

 never seen any specimens that were identical with these 

 figures, but the differences are probably more dependent on 

 the artist of the plates than the specimens themselves. 



Mr Howse mentions that the original of pi. Ixxv. is in the 

 Museum of the College of Physical Science, Newcastle, but T 

 have not seen it. Judcrino from the fioure, however, I am 

 inclined to think tlieir plant has been the Sigillaria 

 ELEGANS, Sternb. sp. 



PI. Ixxvi. Cardiocarpon acutum, L. and H. 



Locality. — Jarrow Colliery. 



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

 Seam. 



Remarks. — Mr Carruthers and other botanists have shown 

 that these seeds were borne by the fossil named Antholithcs 

 Pitcairnice, L. and H., which in turn is the fructification of 

 Cordaites. To show the affinities of the fossils, they are 

 usually now placed in Grand' Eury's genus Cordaianthus.^
