202 So7ithern Cross. 



The body of this Octopus is short and purse-like, dark, dirty 

 oli^'aceous upon the dorsal surface and buff beneath ; l)ody finely 

 granular above and below, the granules 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 Itase by a short web, 

 all of about the same thickness. The right dorsal is shorter than the 

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

 of suckers, the left liaving sixty-seven pairs. 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 

 curious that the upper of the left lateral pair has developed only a 

 single large sucker instead of two. I'he 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. 



Length from web between dorsal arms to the end of body 48 mm., 

 width of body across back 24 mm., from back to front 19 mm. 



Habitat. — Campbell Island.

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 

 purplish brown. The colour of the interior of the aperture is also of 

 a somewhat deeper brown tint. The following measurements will 

 show the variation in the proportions of two selected examples.
