'Challenger 1 Cephalopoda. 229 



The Colour is yellow-ochre, with two pale sienna patches on 

 the back and on the head. 



Hah. Bermuda. One specimen, ? juv. 



Octopus levis, n. sp. 



The Body is oblong, depressed, and bulges a little at the 

 sides ; the mantle-opening extends about one third round the 

 circumference, terminating about midway between the siphon 

 and the eye. The siphon is short and small, extending 

 scarcely one third the distance to the umbrella-margin. 



The Head is almost as broad as the body, and the eyes are 

 large, spheroidal, and prominent, with very small circular 

 apertures. 



The Arms are subequal and short compared with the body, 

 being about three times its length ; they taper gradually to 

 moderately fine points. The umbrella is large, extending 

 about one third up the arms. The suckers are small and 

 prominent and arranged in two rows from the commencement ; 

 a narrow well-marked groove runs across the arm between 

 each two suckers (possibly due to contraction). The hecto- 

 cotylus is well developed, short, and tapering rapidly to a blunt 

 point ; the median groove has about ten transverse bars. The 

 circumoral lip is unusually thick. 



The Surface appears to have been perfectly smooth, but is 

 now covered with wrinkles, due to the action of the spirit. 



The Colour is a dull grey, inclining to stone-colour below. 



Hab. Off Heard Island, Southern Ocean, 75 fathoms 

 (Station 151). Four specimens, 1 $ , 1 J juv., 2 ? juv. 



Octopus Januarii, Steenstrup, MS. 



The Body is rounded, widening a little posteriorly • the 

 ventral groove is very faint. The mantle-opening terminates 

 just below the eyes. The siphon is bluntly conical and ex- 

 tensively attached to the umbrella ; it extends less than half- 

 way to the umbrella-margin. 



The Head is small and the sides are entirely occupied by 

 the enormous eyes, which are swollen and globular, but with 

 very small palpebral openings. The skin covering them is 

 so thin that the dark pigment within is distinctly visible. 



The Arms are unequal, the dorsal pair being the largest- 

 on an average they are four times as long as the body. The 

 ■umbrella is about equally wide all round, except that it is 

 a little shorter between the two ventral arms. The suckers 

 are comparatively small, prominent, and separate ; more 

 widely in one specimen than in the other, probably owing !<•
