 mm. in length, has in Needham's sac 22 spermatophores m^easuring

A male specimen from station 4957, which, though only 71 cm. long, 

 is already mature enough to produce spermatophores, is referred 

 with great hesitation to the present species. The v/arts on the surface 

 are conical, roundish, and not continuous with one another at base 

 as in other specimens. The suckers on each arm become rapidly 

 larger to the eighth pair; then tliere come about four pairs of mark- 

 edly enlarged suckers, which are in their turn succeeded by five or six 

 pairs of rapidly diminishing suckers. The suckers on the hectocoty- 

 lized arm number only 41 pairs, being several pairs fev/er than in 

 the ordinary form.
