A MONOGRAPH OF THE EXISTING CRINOIDS 413 



d 1 . Cirri longer and more slender, more than one-tenth of the arm length; longest cirrus 

 segment (third) from three to three and one-half times as long as the median width, 

 those following rapidly becoming shorter, so that the antepenultimate is slightly 

 longer than broad and the penultimate is about as long as broad; the sixth and follow- 

 ing have sharp and prominent dorsal processes; 60 arms (Java Sea; 88 meters).
