back and sides, becoming paler on the ventral surface and on 

 the funnel. The colour is due to minute chromatophores, 

 which are closely crowded together on the dorsal surface of 

 the head, body, arms, and web, more scattered on the ventral 

 surface, and sparsely dotted on the funnel. Chromatophores 

 occur also to a slight extent on the sides of the arras outside 

 the limit of the web, especially on the inner (dorsal) aspect. 

 Chromatophores are completely absent from the internal (oral) 

 surface of the arms and web, except for a few at the tips of 

 the arms. 



The skin is of a firm consistency and there is no lateral 

 fold of the mantle. 



The papulation is characteristic. All over tlie dorsal 

 surface of head, body, and web there are papillary areas ; 

 these are more or less circular patches of a lighter colour than 

 the surrounding skin, having in the centre a low conical 

 papilla, while round the periphery stand six or seven smaller 

 papillge. In a large female these areas are as much as 7 ram. 

 in diameter, and the peripheral papillee are distant from the 

 central one ; but in two smaller males the areas are smaller 

 and less well defined, and the peripheral papillaj are set close 

 round the base of the central papilla. The papillae are 

 whitish in colour, owing to the absence of chromatophores 

 from their tips. These papillary areas are not found at the 

 sides nor on the ventral surface of the web. 



Above the eyes, which are small, there is a large conical 

 cirrus, 2-3 mm. high, on which are set a number of small 

 papilla (much as in some specimens of Polypus arcticus, 

 figured by Verrill). Round the eyes, but not extending to 

 the lower lid, are a number of large papillse, which may have 

 subsidiary papillee at their base. 



It is not improbable that the "papillary areas" are directly 

 comparable with the papillated cirrus above the eyes. One 

 has only to suppose them erectile to have the homology 

 clearly demonstrated. In the two small males the areas have 

 indeed much the look of half -collapsed papillated cirri. 



The ventral surface is perfectly smooth. 



The funnel is large, 1-6 cm. long in the smallest male. 

 The free margin below the mantle-flap shows a broad sinus. 



The arras are stout and well developed. The order of size 

 is 1, 2, 3, 4, but the differences are not great. The dorsal 

 arms (measured from the beak) are a little more than three 

 times the length of the mantle (measured dorsally to the eye). 

 There is a strong web which occupies from one-quarter to 

 one-tbird of the length of the arms. It is more or less equally 

 developed between all the arms, except between the ventral
