Disc large, rounded, smooth and shining above, with numerous 

 small scales ; the scales below slightly larger ; the whole covered 

 with a smooth skin. Arms broad at base and narrowing rapidly 

 but not abruptly, quite delicate at tip ; arm-spines moderately stout, 

 pointed, generally three, with two tentacle-scales ; beyond the middle 

 of the arm one scale.

It is with some diffidence that I assign to this species (of which 

 it is known that specimens exhibit marked variability) two examples 

 from Franklin Island (29-8'^ Fahr., 10-24 fathoms), as they appear 

 to want the large pedicellariae that are so characteristic of the 

 creature ; the general condition of the collection, with other points 

 for consideration, apparently justifies the course adopted. 



Distribution. — Apparently circumpolar.

This species has been so fully discussed by Professor Alex. 

 Agassiz in his ' Challenger ' Keport that it would be superfluous to
