PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 13 



proximal surfaces pitted as in younger specimens. The distal end of each narrows to 

 a bar which bends in over the disk. 



The arms are of 19 brachials. Pinnules of up to 9 or 10 segments occur on the 

 ninth and succeeding brachials; the lower pinnules are not yet beginning to form. 

 There are strong side- and cover-plates, of the same nature as those of the adult 

 Notocrinus virilis, along the ambulacra. There are a few irregularly arranged sacculi 

 along the arms.
