152 NATURAL HISTORY OF ARCTIC AMERICA. 



longer rays, with three to five shorter reproduced rays-on one side. The 

 rays are rounded, and uniformly covered with small clustered spinules, 

 arranged in divergent groups on each plate. The plates are regularly 

 arranged, both transversely and longitudinally, and more closely united 

 than in Asterias and Leptasterias. The plates of the ventral rows are 

 directly united with the adambulacral, so as to leave no spaces between 

 for the papulaB, which are, therefore, absent along the ventral surface next 

 the adambulacral plates ; on the dorsal surface they are usually arranged 

 in pairs. The major pedicellariae are arranged along the edges of the 

 ainbulacral grooves, and a few usually occur in the adoral angles, between 

 the bases of the rays.
