OphiophoUs aculeata is given with some doubt by Fewkes (10) 

 from Lady Franklin Bay, Grinnell Land ; but the determination is made 

 from a drawing, and it is said of it that it "also resembles OpMocoma". 

 I am most inclined to think that the brittle-star in question is not 

 OphiophoUs aculeata, but Ophiacantha bidentata.
