DESCRIPTION OF SPECIES. PP. 97 



Slgillaria Brardii^ Brongt. 



This species has not been seen in W. Va., bnt near Wash- 

 ington, Penn. it is very abundant in the roof of the Wash- 

 ington coal. 



CORDAITES, Ung. 



Cordaites crassinerms, Sp. nov., PI. XXXVII, Fig. 10. 



Fig. 10, PI. XXXVII, seems to represent a species of 

 Cordaites quite different from any hitherto described. The 

 fragment has a very tapering form, and is somewhat thicli 

 and coriaceous. The nerves are very large and coarse, and 

 are seen to branch again and again in leaving the point of 

 attachment or base of the leaf. This plant may not belong 

 to Cordaites^ it may possibly represent a ijsygmopliyllum. 

 Not enough is shown to determine this point. 



Habitat. — Roof -shales of the Waynesburg Coal, Cass- 

 ville, W. Va. 



Oenus ? PL XXXVII, Fig. 4. 



We have given in Fig. 4, PI. XXXVII, a very curious 

 looking plant, of which we have not found more than one 

 specimen, which is not sufficient to fix its generic position. 

 It is flabellate in outline, and possesses rigid looking ribs 

 which diverge from the central axis, and often fork before 

 reaching the margin. The true termination is not preserved. 

 It has some resemblance to Aplilehia patens Germ., Stein. 

 Fl, V. Wet. u. Lobj. The epidermis of the plant has a 

 smooth aspect marked with the strong impressions of the 

 ribs.
