'I'lic liddy of tliis Octoinis is short and j)Ui-se-like, dark, dirty 

 olivaceous upon (lie dorsal surface and buff' beneath ; body finely 

 j,n~anular above and below, the f»ranules small and very close together 

 on the ventral surface ; above each eye is a small compressed cirrus. 

 Arms (in spirit), keeled above, connected at the l)ase by a short weV), 

 all of about the same thickness. The rifjht dor-sal is shorter than the 

 left, probably bitten by a fish or crustacean; it has thirty-eight pairs 

 of suckers, the left having sixty-seven ]iair8. The suckers are of 

 moderate size excepting the seventh pair from the base on the two 

 lateral pairs of arms : these are enormously developed and stand out 

 4 mm. from the surface and are about the same in diameter. It is 

 cmions that the upper oi" the left lateral pair has developed only a 

 single large sucker instead of two. The presence of these large 

 suckers indicate the male sex of the specimen, and this is sub- 

 stantiated by the hectocotylized lower arm of the right lateral pair. 

 This has only thirty-six pairs of suckers, whereas the corresponding 

 arm on the other side has seventy-five pairs.

This Antarctic whelk has hitherto been only known from 

 Kerguelen and Heard Island. The specimens in the present 

 collection are mostly a little narrower than those from Kerguelen 

 and generally rather darker in colour, in some instances being dark 

 l)urplish lirown. The colour of the interior of the aperture is also of 

 a somewhat deeper l)rown tint. The following measurements will 

 show the variation in the proportions of two selected examples.
