Bell (6) proposes an arrangement of the species .of A sterias, and sug- 
gests a method of formulation, by means of which their leading characters 
may be rapidly recognized ; a brief method of referring to the descrip- 
tions of known species is also adopted.

small, not widely open, the modified spines of the mouth-organs gene- 
rally Goniasterine in arrangement ; the ventral intermediate plates con- 
tinuous, but not imbricated, bearing short spines, which in character and 
arrangement recall the same parts in Asterina. Marginal plates almost 
completely confined to the sides of the arm and disk •; . . . the whole of
