surface, and a well developed guard which is not, like that of 

 C. grandis, of a length greater than the width of the sporangiophore. 

 The brace is usually distinct. — Figs, i, 2, 8-10. 



Typical material has been collected from the roof shales of Coal B** at the 

 Boston mine, Pittston, Luzerne County, Pennsylvania, and also from "a locality 

 high on the steep eastern slope of the gorge of the Youghiogheny River, directly 

 south of the mouth of Deep Creek, i mile below Swallow Falls, Garrett County, 

 Maryland, at a horizon in the Allegheny formation (near that of the Lower 

 Kittanning coal) 170 ft. beneath the horizon of the Davis seam. 



Cantheliophorus grandis, n.sp. — This species is well char- 

 acterized by a long slender blade perpendicular to the cone axis, 

 but apparently less rigid than that of C. lineari folium, and by a 

 large sporangiophore with a very long guard which is nearly 

 perpendicular to the pedicel. It terminates in an acute, abruptly 

 upturned beak. The somewhat rugose-undulate surface appears, 

 with the aid of a lens, to be minutely rugulose-bullate in part. The 

 brace is not conspicuous. — Fig. 3. 



The type material has come from a shale lens beneath the massive friable 

 conglomeratic sandstone in the rock quarry south of the county road, at 

 Holmes, West Virginia, on the Baltimore and Ohio Railroad, i mile west of 

 Corinth, at a horizon very close to the top of the Pottsville formation. 



Cantheliophorus cultriformis (Lesquereux) . — The con- 

 spicuous features of this species are a large wide sporangiophore 

 and a wide keel which with the form and attitude of the blade 

 serve well to distinguish it. The latter curves slightly upward 

 beyond the middle and usually opens somewhat at the same time. 

 The surface is granulose or, like the last, minutely rugulose-bullate; 

 the units like those of the next species are somewhat transversely 

 /elongate. — Figs. 5-7. 



This species occurs in the shales of the floor of the Darlington coal at 

 Cannelton, Beaver County, Pennsylvania, correlated by White (36) with the 

 Upper Kittanning. 



Cantheliophorus subulatus, n.sp. — This species is sharply 

 defined by the expansive development of the sporangiophore and 



* The more important coal seams in the anthracite field of Pennsylvania beginning 

 at the base of the Lower Productive Measures (Allegheny formation) have been listed 

 alphabetically in certain State Geological Survey publications. Coal B is supposed 

 to be the equivalent of the Lower Kittanning of western Pennsylvania.
