The cirri are 7 mm. long, composed of 10 segments of which the third and fourth are 
the longest, two and one half times as long as the diameter of the greatly expanded distal 
ends, and the antepenultimate is one third again as long as broad. 
The arms, which resemble those of the other species of the genus, are 35 mm. long.
