Cylicocrinus, S. A. Miller, 1892, Advance 

 Sheets 18th Rep. Geo. Sur. Ind., p, 31. 

 [Ety. kuttx, //us, a cup ; krinon, a lily.] 

 Calyx urn-ahaped, truncated below. 

 Basals 3, expanded; primary radials, 

 3 x 5,— the first one very large ; second 

 one, small, quadrangular ; third, small, 

 pentagonal ; secondary radials 2 or 

 more; arms 10. Regular internuliuls 

 consist of one large plate followed by 

 very small ones between the arm-bases 

 that connect with the vault-plates ; first 

 azygous plate in line with the first ra- 

 dials, followed by three plates in the 

 second and in the third ranges, which 

 are connected with smaller plates that 

 connect with the vault. The vault is 

 convex and covered with minute plates, 

 except the ambulacral grooves, winch 

 are open and have serrated edges as if 

 protected by some kind of cilia. The 

 primary radials resemble those in some 

 species of Batocrinus ; the azygous area 

 resembles Saccocrinus ; the vault is 

 different from that in all other known 

 genera of crinoids. Type Cylicocrinus 

 canaliculars, described at the same 

 place from the Niagara Gr.

 [Ety. kuphot, bowed down ; krinon, 

 lily.] Calyx obconoidal or obpyramidal 

 as high as the first interradials, then 

 rapidly expands and curves downward 

 until the periphery and ambulacral ori- 

 fices are directed below a horizontal 

 line. Basals 5, forming a pentagonal 

 disc; sub-radials 5, hexagonal,except one 

 which is truncated by the first azygous 

 plate ; it is heptagonal ; primary radials 

 3x5; 3 of the first ones heptagonal,
