NEW FOSSILS FROM THE UPPER CARBONIFEROUS OF 



KANSAS. 



BY J. \V. BEEDE. 

 With Plate V. 



The following will be of interest and value in completing the 

 fauna! succession of the uppermost part of the Carboniferous, as well 

 as for the biologic interest of one of them. 



Ceriocrinus harshbargeri, n. sp. Plate V, figs. 1-lc. 



The distinctive features of this species are : Surface ornamented 

 with both pustules and granules, large interradial supporting plate 

 above calyx, ten short, massive arms. 



Description : Calyx basin-shaped, shallow, quite concave below. 

 Infrabasals partly covered, but located entirely within the body cavity. 

 Stem small and apparently round. The five basals are large, recurved 

 below the middle, concave in the center of the more depressed part, 

 four apparently hexagonal and one heptagonal, and larger than the 

 others supporting the interradial ; all higher than wide, sutures not 

 much depressed. There are five large, massive radials a trifle more 

 than twice as wide as high, well beveled, faceted, and apparently sag- 

 ging a little on the upper articular surface. Interradial large, fully 

 half within the calyx, higher than broad, and the upper portion very 

 strongly curved inward. This plate supports another entirely with- 

 out the calyx, which is comparatively large and appears to be pentagonal 

 when seen from without, the two upper sides being much longer than 

 the rest, making the plate appear triangular at first sight, fitting 

 closely between the arms on either side. The five brachial plates are 

 large, contiguous save on the posterior side, and produced into an 

 obtuse spinous process. Much of the upper surface of these processes 

 is faceted, supporting the costals, and in this manner giving the ani- 

 mal its greater lateral diameter above the calyx, and affording more 

 room for the massive arms which, when closed, form a box around
