the keel, and by the straight, relatively short, slender blade pro- 

 jecting from the extremity of the pedicel without appreciable 

 flexure, the lateral portions folded sharply back for practically their 

 entire length. The surface of the sporangiophore is rugose with 

 m.inute, close, irregular transverse folds which vary much in 

 distinctness in different specimens. — Figs, ii and 12. 



The species occurs in the Cherokee shales (Kittanning group of the Alle- 

 gheny formation) at the Penitentiary shaft, Lansing, Kansas, and in the floor 

 shales of the Darlington coal (Upper Kittanning) at Cannelton, Pennsylvania 

 (Lacoe collection no. 16100 U.S. Nat. Mus.). 



Cantheliophorus ensifer, n.sp. — The salient features of this 

 species are great length of toe (which distinguishes it at once from 

 all others known to us at this time), a straight, rigid, narrowly 

 triangular blade which makes a wide angle with the pedicel, and 

 the smooth surface of the sporangiophore, which is usually thrown 

 into several rather prominent longitudinal folds. The guard 

 extends forward in a position directly above and usually m contact 

 with the superior surface of the blade. — Figs. 15 and 16. 



It is abundant at a horizon 1.25 miles below Swallow Falls, Garrett 

 County, Maryland, along the old lumber tram on the steep eastern slope of 

 the Youghiogheny River gorge, not far below the mouth of Deep Creek, about 

 400 ft. below the horizon of the Davis seam (the top of the Allegheny), and 

 130 ft. below the top of the Pottsville formation. 



Cantheliophorus novaculatus, n.sp. — The noteworthy features 

 of this species are the linear blade reduplicate only near the base, 

 flexed forward into a position nearly parallel to that of the axis of 

 the cone, and the sporangiophore with a line granulose surface and 

 a distinct brace. The keel was never wide, and it appears to have 

 been rather frail, for often it is missing entirely. — Figs. 29 and 30. 



This species is one of rather wide distribution in the Maryland area, and 

 up to this time has been found only within the Allegheny formation. It has 

 been collected by the writer near Warnocks Station. West Virginia, along the 

 Western Maryland Railway, 25 ft. below the horizon of the Davis seam (top 

 of the Allegheny) ; at Barrelville and Sunnyside from the roof shales of the 

 Parker Coal, 50 ft. below horizon of Davis seam; south of Franklin, West 

 Virginia, along the Western Maryland Railway, 75 ft. below the Davis; on 

 the north fork of Jennings Run, northwest of Wellersburg, Pennsylvania, 

 95 ft. below the Davis; along foot path up the cliff above the Western Maryland
