Dorsal cup shallow, basin-shaped, depressed dorsally for 

 the reception of the column ; plates rather thin, strongly con- 

 vex, often somewhat angular, instead of rounded, and deeply 

 depressed at the corners ; radials nearly twice as wide as high, 

 the articular facets facing outward. Anal plate rather small, 

 resting on the broadly truncated end of the posterior basal 

 and supporting two plates in the second range, which also 

 abut against the radials for nearly one-half of their height.

 Measures : Kansas City. 



While the arrangement of the plates in the dorsal cup is 

 precisely the same as in Phialocrinus, with perhaps the excep- 

 tion that the second range of anal plates lies partly within the 

 dorsal cup, and rests against the radials, this form, along with 

 some others, has comparatively thin plates.
