HOYLE: REPORTS ON THE CEPHALOPODA. 39 



organ, found in this position in the genus Abraliopds. 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 speciuien. 



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 specimen figured by Fischer was a very young one, it seems 

 worth while to give a full description 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, attaclied to the body for only about one- 

 half their length : the bx'eadth across the two expanded tins is about two-thiixls 

 the length of the body. The siphon is short and bluntly conical with double 

 supporting bands ; the valve is small, but distinct; the fu7mel-organ consists of 

 a roughly triangular pad, with the sides somewhat excavated ; lying on the doi-sal 

 wall of the funnel on either side of it are two oval pads, with the anterior 

 extremities directed oblii^nely inwards. 



The Head is large and n)unded, distinctly wider than the body: the eyes are 

 globular, occupying the whole of each side of the heail: the ocular aperture is 

 contracted and shows no sign of an emargination. Tbere is otdy a shallow de- 

 pressioa for the si[)hoii. Beluw and behind each eye is the olfactory organ in 

 the shape of a minute papilla. Around the inferior circumference of the eye.
