E = 6 to 4 r. 



A small species with a striking resemblance to A. c/lacialis, but 

 distinguished by the scarcity of major pedicellariae, which are only 

 found in the neighbourhood of the ambulacral groove. Arms 

 convex, rather stout, with a central row of spines and one or two 

 rows on either side, or with one of the rows irregular and poorly 

 developed. Ambulacra rather narrow, bordered by spines which are 

 generally alternately double and single ; on the sides of the lower 

 surface of the arm ordinarily two rows of spines. The greater 

 number of the spines appear very prominent on account of the large 

 number of minor pedicellarise which are developed on them. 



Colour in spirit whitish ; when alive said to be red, violet, or 

 ferruginous. 



Not known to be as much as 5 inches in diameter. 



Distribution. Both sides of North Atlantic ; North Sea ; White 

 Sea. 53-433 fms.
