Remarks. — -The present species differs from all hitherto known 

 Oegopsids in many respects. The choroidal nature of the body, the 

 absence of hooks, the characters of neck and of its appendage, and the 

 shape of fins seem to indicate that it stands in nearest relationship to the 

 Chiroteuthida;, though it lacks luminous organs. However, the final 

 determination of the relationship may well be deferred until a more precise 

 knowledge is gained of the anatomical character of the species.
