 ern Japan, but it is a more slender species and possesses only ten arms. 



Cirri XX, 84-90, 55 mm. long, more slender than those of A. anthus. 



Radials with a moderately prominent dorso ventral ly elo)igate median tubercle ; 

 IBr series with a faint narrow low median carination. 



Ten arms 80 mm. long, slightly more slender than those of .4. anthus, with 

 slightly longer brachials; arms strongly compressed distally as in that species ; 

 but the overlapping spines developed on the brachials are not nearly so long or 

 so stout.
