94 THE VOYAGE OF H.M.S. CHALLENGER. 



Octopus pictus, Brock, Y&r. fasciata, nov. (PI. VIII. fig. 3). 

 Habitat. — Port Jackson, Australia, April 23, 1874; 6 to 15 fathoms. 



The variety differs from the typical form (l) in the somewhat elongated not spheroidal 

 shape of the body, (2) in the inequality in the shape of the arms, (3) in the prominence 

 of the suckers ; none of which are points of great importance, being possibly due to 

 varying states of contraction. 



On the other hand, it agrees in the type of colouring, but here the dark pigment is 

 arranged in continuous bands, which are not broken up into rounded patches as is the 

 case in all the specimens I have seen ; the spots of the type are, however, arranged in 

 rows disposed similarly to the bands. Furthermore, each band contains an opaque-looking 

 median streak like the centre of the spots, and the number of transverse stripes on the 

 arms corresponds roughly in both forms.

 1885. „ „ Hoyle, Prelim. Eep. I., p. 103. 



Habitat. — Bermuda. One young sjjecimen, $ . 



The Body is spheroidal, acuminate behind, and with a median groove ventrally. The 

 mantle-opening extends rather less than half round the circumference of the body, and 

 terminates some distance behind and a little below the eye. The siphon is long and 

 smooth, and attached by nearly all its length to the head ; it extends fully halfway to 

 the umbrella-margin. 



The Head is much narrower, and more depressed than the body ; the eyes are 

 scarcely at all prominent. 



The Arms are unequal, in the order 1, 2, 3, 4 ; about six times as long as the body ; 

 they are very long and slender, tapering but slightly. The umbrella is smaU. The 

 suckers are small, prominent, and closely set, and the first four stand in a slightly 

 zigzag line. The only specimen being a female, no hectocotylised arm was observed. 



The Surface is smooth for the most part, but the skin is wrinkled over the posterior 

 acuminate extremity, owing to the action of the spirit ; there is one very smaU wart over 

 each eye. 



Tlie Colour is yellow ochre, with a pale sienna patch on the back and one on the 

 head.
