longer rays, witli tlirco to five shorter reproiluced raysoii one side. The 

 rays arc rounded, and imifornily covered witli small clustered spinules, 

 arranged in divergent groui)s on each plate. The i)lates ar*» regularly 

 arranged, both transversely and longitudinally, and more closely mrited 

 than in Asierias and Leptastcrias. The plates of tlie ventral rows are 

 directly united Avith the adambulacral, so as to k'a\e no si)aces between 

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

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

 in pairs. The major ])edicellari8e are arranged along the edges of the 

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

 the bases of the rays.
