Like Chun, he also made the mistake of including several other unrelated specimens in the species, including Anne L . Massy's " Helicocranchia pfefferi ", and Chun's " Desmoteuthis pellucida " and " Teuthowenia antarctica " ( now known to be " Galiteuthis glacialis " ); thus coming to the mistaken conclusion that " Teuthowenia megalops " inhabits both the northern and southern hemispheres.
