A MONOGRAPH OF THE EXISTING CRINOIDS 227 



spines on the distal ends at the prismatic ridges. The arms are about 25 mm. long. 

 The cirri are about 6 mm. long with 14 segments of which the last four are about as 

 long as broad. A few cirri, shorter, with 10-12 somewhat longer segments, occur 

 between and below the regular peripheral cirri. These are juvenile cirri that later 

 will be lost.
