Ooniopteris Newberriana^ Sp. nov., PI. XXX, Fig. 2. 



(Frond, tripinnatifid; primary pinnae, triangular in out- 

 line, tapering rapidly toward tlie apex; rachis, rather stout 

 and rigid ; secondary pinnae (pinnules), alternate, linear- 

 lanceolate, narrow, closely placed and going off at almost a 

 right angle with the primary rachis, cut into numerous 

 ovate-acute segments or lobes, which are minutely dentate 

 and become narrower, more acute and more united toward 

 the summit of the pinnae; mid-nerve, well defined; lateral 

 nerves, passing off into each segment or lobe, from which 

 branches proceed in a pinnate manner, one into each tooth, 

 the lower pair of branches proceeding to meet the corre- 

 sponding branches of the adjacent segments at the sinus, 

 but not uniting with them.) 



This beautiful and linely cut plant has a thick coriaceous 

 leaf substance which leaves a shining film on the stone. It 

 differs slightly from the typical GoniojDterids in the lowest 

 pair of nerves failing to anastomose with their neighbors, 

 but its features in all other points corresponds so fully with 

 those of the genus that we do not feel justified in separat- 

 ing it from Goniopteris. It is much like Pecopteris argida 

 of Brongt., Schimper's Goniopteris arguta^ but much more 

 finely cut, and is also smaller. It is named in honor of Dr. 

 J. S. Newberry, the distinguished palaeobotanist of Colum- 

 bia College.

Cymoglossa, Schimper. 



The genus Cymoglossa was founded by Schimper on the 

 Pecopteris Goeppertl of Morris, a plant from the Permian 

 of Russia. According to Schimper it includes plants with 

 the facies of Goniopteris, but having the tertiary or ulti- 

 mate nerves of the lobes or pinnules in large part forked. 

 He gives the following as the generic character : 



"Frond pinnate; pinnae, broadly oblong, or elongate- 

 lingulate, undulate (whence the name ; glossa, tongue.
