42 PP. REPORT OF PROGRESS. FONTAINE & WHITE. 



the roof-shales of the Washington Coal, 175 feet above the 

 Waynesburg Coal. It occurs in company with CalUpteris 

 conferta,Brongt, covering with its leathery pinnae, tlie sur- 

 face of a thin layer of calcareous iron ore. It seems to be 

 allied to Splienopteris oxydata, Goepp. and Sphenopteris 

 lyratifolia, Weiss, both of • which occur in the Permian of 

 Europe. Unfortunately the maceration, to which the frag- 

 ments have been subjected, disguises somewhat the details 

 of the plant, and it is found only in fragments. In some 

 features it resembles CalUpteris, especially in its thick, 

 dense parenchyma, in the immersion of the nerves, and in 

 the occurrence of pinnules on the principal rachis. 



Habitat. — Roof-Shales of the Washington Coal, near 

 Brown's Bridge, Monongalia Co., W. Va. 



Sphenopteris deiitata, Sp. no v., PI. V, Figs. 7-8. 



Frond, bi or tripinnate ; pinnae, linear-lanceolate, alter- 

 nate, going off at almost a right angle ; pinnules, ovate, 

 slightly contracted at the base, and furnished with sharply 

 pointed teeth ; primary nerve, faintly marked in some of 

 the pinnules ; lateral nerves, wanting, or concealed in the 

 thick leather-like parenchyma of the pinnules. 



This beautiful little plant, is closely allied to Splienopteris 

 Sararia, Weiss, but it differs from it in its more pointed 

 pinnules, and its apparent want of lateral nerves. 



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

 ville, W! Va. 



Splienopteris species ? PL XI, Figs. 5-7. 



The fragments depicted in Figs. 5, 6, 7, PI. XI, may rep- 

 resent a new species, but they are too small and imperfect 

 to fix the specific character. Fig, 6 resembles some forms 

 of Splienopteris Lesquereuxii, Newb. and may be identical 

 with it, but the lobes of this plant are sharper, and more 

 deeply cut, than those of the above named Splienopteris.

Splienopteris auriculata, Sp. no v., PL VII, Figs. 3-4. 

 Frond, bi or tripinnate ; principal rachis, pretty stout.
