n=O bOmhe 
A small species with a striking resemblance to A. glacialis, but 
distinguished by the scarcity of major pedicellarie, 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 pedicellarize 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.
