Observations on the Anatomy of a rare Cephalopod (Gonatus fabricii)

Authors

  • William E. Hoyle M.A. (Oxon.), F.R.S.E.


Summary.

In addition to the general sketch of the anatomy of an interesting form, the preceding pages record the existence of several tracts of cartilage hitherto unobserved in the Cephalopoda, and give details regarding the structure of the pen-sac and the development of the pen, as well as new facts regarding the structure of the funnel-organ. The genus Gonatus is regarded as being somewhat more nearly related to Onychoteuthis than to Enoploteutkis, but as much further removed from both than they are from each other. The creation of the sub-family Gonatidæ is held to be justified.
