 species the type of a new genus, Cryp- 

 toblastus, and referred to the same 

 genus G. pisum. The generic charac-

 [Ety. graphion, writing instrument; 

 krinon, lily.] The authors described 

 this genus as having only basals and 

 radial s, but as re-defined, by Wachs- 

 muth, there are five basals concealed 

 by the column ; subradials 5 ; radials 

 1x5, upper margins straight ; brachials 

 1x5; sutures gaping ; arms 10, long, 

 heavy, short joints, parallel sutures ; 

 pinnules long ; azygous interradial 1, 

 small, but extending above the radials ; 

 strong ventral sac or proboscis. Type 

 G. encrinoides.
