228 " ENDEAVOUR ' SCIENTIFIC RESULTS. 



animals as C. hoylci Goodrich, and C. chuni Pfeffer are but 

 yovang stages of some of the larger species. Compared to the 

 one under discussion, however, the discrepancies are of such 

 a nature {e.g., the jully toothed arm suckers of C. hoylei, the 

 partially toothed tentacle suckers of C. chuni, etc.) that I doubt 

 whether either will ever prove identical with it. 



C. miranda is not a typical Calliteuthis, as it lacks accessory 

 chitinous structures on the tentacle club ; it is not a typical 

 Stigmatoteuthis, as it possesses the series of cartilaginous 

 tubercles on the dorsum and dorsal arms, and there are too 

 many series of photophores on the ventral arms ; it is not a 

 typical Meleagroteuthis, as there are far too few photophores 

 over the whole body. In several respects it stands midway 

 between the two latter groups and helps materially to break 

 up the boundary between them. It shares with all other 

 members of the family the extraordinary asymmetry of the 

 eyes, head, and head photophores, a phenomenon which is 

 still as inexplicable as ever.

Animal moderately large, loliginiform ; its body (Figs. 

 10-11) slightly compressed, more or less cylindrical in front, 

 tapering at first gradually, then very rapidly between the 

 fins to an acute point ; mantle margin with only a very weak 

 nuchal sinuation and an emargination below the funnel.
