CLASS CRINOLDEA. 

 ORDER PAL^OCRINOIDEA. 

 FAMILY ACTINOCRINID^E. 



BATOCRINUS GERMANUS, n. Sp. 



Plate 7, Fig. 1, basal view; Fig. 2, azygous side, some of the 

 plates of the vault broken away; Fig. 3, summit 

 view of the same specimen. 



Body medium size, calyx and vault subequal, giving it a 

 biturbinate or lenticular shape. Calyx moderately truncated at 

 the base, rapidly spreading and about two and a half times as 

 wide as high; arm openings directed nearly horizontally or di- 

 rected upward at an angle of only a few degrees; plates thick, 

 very highly convex, this convexity on the radial plates being 

 transverse and angular. No radial ridges. Surface granular. 



Basals very short, forming an hexagonal disc, with slight 

 re-entering angles, deeply notched at the sutures, and project- 

 ing cuneiform edges a little below the end of the column, and 

 having a round, deep, columnar depression for the attachment 

 of the column. The basal disc is about one-half wider than 

 the diameter of the column. The sutures are notched or beveled 

 nearly to the first radials, and the columnar cavity is deeper. 

 First radials about one-half wider than long, three hexagonal, 

 two heptagonal, with the superior sides slightly arcuate. Each 

 one is transversely convex, the elevation being obtusely angu- 

 lar. Second radials quadrangular, and from one-half to twice 

 as wide as long. Third primary radials rather smaller than
