The body of this octopus is shoi-t and purselike, dark, dirty olivaceous upon the 

 dorsal surface and buff beneath ; body 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 base by a short 

 web, all of about the same thickness. The right dorsal is shorter than the left ; 

 it has 38 pairs of suckers, the left having 67 pairs. The suckers are of moderate size, 

 excepting the seventh pair from the base on the 2 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. The presence of these large suckers indicate the 

 male sex of the specimen, and this is substantiated by the hectocotylized lower arm 

 of the right lateral pair ; this has only 36 pairs of suckers, whereas the corresponding 

 arm on the other side has 75 pairs.
