1. Polypus Campbell!, E. A. Smith, 1902. Plate 69, fig. 3. 



Polypus Canipbdli, E. A. Smith, Voy. " Southern Cross," Moll., 1902, 201, 

 pi. 24, f. 7; Suter, T.N.Z.I., xxxviii, 1905 (1906), 333; Subantarct. 

 Islds. N.Z., i, 1909, 48. 



Body short and purse-like, 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 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. The presence of these large suckers indicate the 

 male sex of the specimen, and this is substantiated by the hecto- 

 cotylized 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. (E. A. Smith. 



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.

2. Polypus communis, J. Park, 1885. 



Octopus communis, J. Park, T.N.Z.I., xvii, 1884 (1885), 198; Chall. Kc-p.. 

 xvi, 13, 220 ; Index, 57.. 



Body oval, stout, fan-shaped behind, smooth, without fins. Head 

 large, long, rounded. Eyes large, round, prominent. Arms long, 

 tapering, unequal ; dorsal pair one-third longer than the ventral pair. 

 The hectocotylus is shorter and more robust than the other arms, 

 ending abruptly in a long, flattened process with a deep longitudinal 

 groove. Suckers in 2 rows, not opposite, sessile, tenth sucker in 

 row largest, gradually diminishing both ways ; those on dorsal arms 

 one-third larger than those on ventral arms. The suckers vary in 

 number from 138 pairs on the largest arms to 110 on the shortest, 

 while the hectocotylized arm is furnished with only 52 pairs. Colour : 

 Above, dark steel-grey, blotched irregularly with pale grey, almost 

 black round the eyes ; below, pale grey, blotches smaller and less 

 numerous. (J. Park.) 



Measurements. Length of body and head, 1 ft. 1 in. (330 mm.) ; 

 length of dorsal sessile arms, 3 ft. (915 mm.) ; length of ventral sessile 

 arms, 2 ft. (610 mm.) ; length of hectocotylus, 1 ft. 6 in. (457 mm.) ; 

 length of other sessile arms, 2 ft. 9 in. (838 mm.) ; circumference of 

 body, 1 ft. 5 in. (432 mm.) ; diameter of eyes, 0-5 in. (13 mm.) ; dia-
