HOYLE: REPORTS ON THE CEPHALOPODA. 39 
organ, found in this position in the genus Abraliopsis. At this stage of growth 
there is no trace of hooks : they are represented only by suckers. "The colored 
drawing here reproduced was made on the voyage immediately after the capture 
of the specimen. r 
The specimen [H. 143] captured on the later cruise shows rudimentary 
phosphorescent organs, when examined under a lens just as the alcohol has 
evaporated from the surface. One ventral arm has a little brown patch near 
the tip.

As the type speeimen figured by Fischer was a very young one, it seems 
worth while to give a full deseription of a more mature form. 
The Body (Plate 7, Fig. 6) is conical; about three times as long as broad. 
The fins are each broadly elliptical, attached to the body for only about one- 
half their length : the breadth across the two expanded fins is about two-thirds 
the length of the body. The siphon is short and bluntly conical with double 
supporting bands ; the valve is small, but distinct; the funnel-organ consists of 
a roughly triangular pad, with the sides somewhat excavated; lying on the dorsal 
wallof the funnel on either side of it are two oval pads, with the anterior 
extremities directed obliquely inwards. 
The Head is large and rounded, distinctly wider than the body: the eyes are 
globular, occupying the whole of each side of the head: the ocular aperture is 
contracted and shows no sign of an emargination, There is only a shallow de- 
pression for the siphon, Below and behind each eye is the olfactory organ in 
the shape of a minute papilla, Around the inferior circumference of the eye,
