464 PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [May 20, 



the leaf appear to me more those of a Fern, possibly allied to Adian- 

 tum or Lindscea. 



14. Sphenopteris recitrva, spec. nov. PI. XVII. figs. 7 & 8. 



Leaflets small, cuneate, terminating the divisions of a dichotomous 

 winged petiole. 



This Plant is represented by small and obscure fragments on the 

 Perry sandstone. Its venation is not preserved ; and it may be a 

 small Cychpteris with terminal pinnules, like my C. Acadica, from 

 the Lower Coal-formation of Nova Scotia. 



15. Trichomanites filicula, spec. nov. PI. XVII. figs. 12 & 13. 

 Pinnules slender, attached to long petioles, and bifurcating into slender 



points. 



This species approaches T. Beinertii and T. adnascens, and there 

 are indications that, like the latter, it may have been parasitic on 

 petioles or branches of other Plants. Numerous specimens occur at 

 Perry, but all are small and somewhat obscure. 



16. PlLICES INCERT2E SEDIS. PI. XVII. figS. 10 & 16. 



Among the Plants collected by Mr. Brown are two somewhat ob- 

 scure examples of the frond or pinnule represented in PI. XVII. 

 fig. 10. It is of a linear form, with crenations or teeth on the mar- 

 gins. The midrib is delicate ; the nerves, which are rather indistinct, 

 appear to be netted near the midrib in the manner of Glossopteris, 

 Brongn. ; but they are distinct toward the margin, where there are, 

 in the sinuses of the teeth, dark spots, which are probably remains of 

 fructification. These evidences of marginal fructification remove the 

 Plant entirely from Glossopteris ; and I am not aware of any other 

 genus of fossil Perns in which it could be placed. It may have been 

 allied to such recent genera as Lonchitis or Hypolepis. The speci- 

 mens are, however, so imperfect and obscure, that I content myself 

 in the meantime with representing what I can make out of their 

 form and venation, trusting that they may at some future time be 

 named from more perfect examples. 



The frond or pinnule shown in PI. XVII. fig. 16 represents another 

 uncertain species. It is cuneiform in shape and broad at the base in 

 all the specimens that I have seen. It has not been found attached 

 to a stem or petiole. Its venation is less coarse than that of Cychpteris 

 Brownii, and much coarser than that of C. Rogersi or C. JacTcsoni. 

 It approaches also more nearly to parallelism, and seems less forked. 

 This leaf would go into the genus Noeggerathia of some authors, and 

 may be a distinct species ; but I am by no means certain that it is 

 not a young state or marginal division of Cychpteris Brownii, and 

 hence refrain, for the present, from naming it. 



17. Carpollthes lttnattts, spec. nov. PL XVII. fig. 11. 



Base rounded regularly, apex broadly truncate and mucronate ; 



nucleus surrounded by a narrow margin. 



This species is described from a single specimen, which, however, 

 appears sufficiently well characterized.
