superior ones confluent ; terminal leaflet large, rounded or 

 lobate, angular, obtuse ; nerves entirely obsolete ; surface 

 covered with small shining scales ? 



Genus HYMENOPHYLLITES. Gopp. 



42. Hymenophyllites furcatus ? Gopp. Frond tripinna- 

 tifid ; common rachis subulate, with its divisions nearly per- 

 pendicular ; pinnules oblique, deeply pinnatifid ; lobes bitri- 

 fid ; the inferior ones nearly pinnately divided, with the 

 divisions linear, lanceolate, oblique, plain, and slightly acute 

 or truncate. It differs by the divisions being slightly trun- 

 cate, (an species propria). 



43. Hymenophyllites Hildreti (spec. nov.). Frond 

 bipinnate ; secondary pinnae lanceolate, open, alternate, the 

 inferior bipinnately, the superior pinnately divided ; divisions 

 linear, acute. 



44. Hymenophyllites capillaris (spec. nov.). Differs 

 from the former by its very narrow and longer divisions. 



Genus PACHYPHYLLUM. Lesqx. 



Frond large, thick, membranaceous, broadly oval or lanceolate 

 in outline, either pinnately or irregularly lobed ; radical or 

 borne on a thick rachis ? divisions short, lanceolate, obtuse, or 

 long linear-flexuous ; nerves thick, compound and parallel near 

 the base, separating above and solitary in each division, or 

 disappearing totally. 



45. Pachyphyllum fimbriatum (spec. nov.). Frond large, 

 pinnate; pinnules sessile, distant, oblique, pinnately divided; 

 divisions lanceolate, acute, short, fringed on the slightly re- 

 curved margins ; nerves pinnately branching ; nervules simple 

 in each division. 



46. Pachyphyllum affine (spec. nov.). Differs from the 

 former only by the flattened and entirely smooth margins of 

 the divisions. 



41. Pachyphyllum hirsutum (spec. nov.). Frond bipin-
