Remarks.—The specimen from station 5182 is no less than 120 mm. 
in horizontal diameter and is the largest specimen known of this 
species. The “bearded” part of the oral side is very large, the 
primary tubercles being confined to a narrow zone distally. 
The specimens from station 5103 are somewhat darker than usual, 
perhaps colored by comatulids; in life the color evidently was the 
usual, the label stating “ten lines of sapphire spots in interambulacral 
areas, on brown dorsal surface, below white.” 
Parasite—Two of the small specimens from stations 5358 and 5360 
carry a small parasitic gastropod (¢Mucronalia).
