Before giving a synopsis of tlie species, we will first add a 

 few remarks on the works and papers of previous writers on 

 Yorkshire Coal Plants. 



I. On Fossil Reliquia of Unknown Vegetables 

 in the Coal Strata. — By the Rev. Henry Steinhauer. 

 (Trans. Amer. Phil. Soc, 1818). In this paper the following 

 Yorkshire specimens are described : — 



Phytolithus verrucosus. P. 268, pi. iv., figs, i — 6. 



'The specimens more immediately examined were found in 

 the neighbourhood of Fulneck, near Leeds, or in the space 

 included by the towns of Leeds, Otley, Bradford, Hudders- 

 field, and ^Vakefield, but have also found it on tlic top of 

 Ingleborough. . . . ' 



This is the well-known Stiginaria Jicoides. His fig. 3 

 shews the termination of a root. 



PhytolitJius sulcatus. P. 277, pi. v, figs, i — 2. 



That given at fig. i has been made the type of Calainites 

 steinhaueri hy Brongniart.* I believe, however, that Cala- 

 inites steinhaueri is only a large basal portion of Calainites 

 suckoivii Bngt., and not a distinct species. Steinhauer's fig. 2 

 is also apparently referable to Calainites suckotoii. 



Phytolithus caiitellatiis. P. 280, pi. vi., figs. 2 — -6. 



These figures represent more than one species of 

 Lepidodendron.
