S}). Char. — Body elongate ; disc probably of medium size, but general 
proportions unknown. Bays long, very slowly tapering, straight sided, 
forming with one another an angle of from 60° to 75°; abactinial surface 
moderately convex, bearing several (five or six) rows of small convex poly- 
gonal plates, inclusive of the marginal pieces, and becoming much crowded 
at the apices of the rays, where they form oblique rows ; marginal plates 
strong, short, thick, high, or somewhat pyramidal, and subhexagonal in out- 
line. Actinial surface more or less flattened; avenues narrow, straight sided; 
ambulacral plates unknown; adambulacral plates transversely oval, thick, 
and arched, clothed with short, subulate, stout spines, arranged in about 
three alternating rows ; oral plates very small, the two halves of each, 
pustuliform. Madreporiform plate unknown.

is a straight rayed, and non-petaloid form, of the true Palceaster outline, and 
so differing from the latter, as well as in the increased number of plates on 
the abactinial surface.
