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

 Waynesbnrg Coal. It occurs in company with Callipterls 

 con/erta^Brongt, covering with its leathery pinnge, the sur- 

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

 allied to Splierio]jteris oxydata^ Goepp. and ^plieiiopteris 

 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 Calllpteris^ especially in its thick, 

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

 the occurrence of ]3iiini^l<^s on tlie principal rachis. 



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

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



Sphenopteris deutata, Sp. nov,, PL V, Figs. 7-8. 



Frond, bi or tripinnate ; j^innae, 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 Splieiiopteris 

 Sarana^ Weiss, but it differs from it in its more pointed 

 pinnules, and its apparent want of lateral nerves.

Sphenopteris species f PI. 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 Splienopter is 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 S2:)henopteris.
