the report, vary in size from one to three inches long. To the genus Neuropteris should 

 be added some specimens of the formerly admitted genus Cyclopteris var. Cyclopteris 

 obliquua, Brgt., and Cyclopteris ingens, Lindl. and Hutt., both found at Morris. The first 

 is referable with doubt to Neuropterus hirsuta, the second to JSTetiropteris rarinervis. I 

 have seen six specimens of this last form, and ten of the first. 



* An obscure specimen. May represent a form of Alethopteris aquilina, Brgt., 

 which is abundant in the shales of the coal at Morris, and of that of Neelysville and 

 Duquoin. 



f A poor specimen. May be referable to Alethopteris Coxiana, Lsqx. 



J A new species, sent for determination, by Mr. Wilbur, of Chicago. It is a fruit- 

 ing frond, lanceolate, taper pointed in outline, bipinnately divided. The pinnae are 

 linear, narrow, undulating, rather turned upwards from the middle, with a narrow 

 rachis ; the pinnules are very narrow, short, linear, obtuse, deeply marked in the stone, 

 very numerous, perpendicular to the rachis, with a strong medial nerve, veinlets obso- 

 lete. In the upper part of the frond the pinnae decreases in size and pass into simple 

 pinnules. On the same stone there are a few detached pinnules of Alethopteris Coxi- 

 ana. The new species might be its fruiting frond, though there is no likeness what- 

 ever in the leaflets. 



§ Most abundant in stems and floating roots in the shales under the coal at Morris.
