linckia leviuscula, Stimpson, n. s. 



Disk very small ; rays elongated, cylindrical, in length 

 2| times the diameter of the disk. Upper surface covered 

 with slightly protuberant, uniform, spinulose paxilli, which 

 are somewhat irregularly crowded together, leaving deep 

 but very narrow chinks leading to the holes in the network 

 of the skin. The spinules of the paxilli are so crowded that 

 the surface of each appears nearly smooth. Below the 

 paxilli are still more crowded, but are here quadrate in 

 shape and arranged in three or four rows on each side of 

 the ambulacral furrow ; those of the ambulacral row hav- 

 ing their spinules less crowded and somewhat longer, form- 

 ing the marginal series. Diameter, two inches. 



Found in Puget Sound, by Dr. Suckley.
