peculiar feature of the oral surface is that the arms and web are coloured the same 

 purple hue, except for a circular band of paler colour about 30 mm. deep, which passes 

 round the mouth at the level of the 14th to the 20th sucker. The oral surface of the arms 

 (but not of the suckers, which is ochreous) preserves the purple shade ^. 



The mantle-aperture is very narrow ; but it is still to some measure free of the funnel, 

 and not in contact with it at its side. The temporary adhesion of the funnel to the mantle- 

 rim is, however, very perfect. The surface of the funnel is excavated to receive the

mantle-edge and the two elements of the locking apparatus are very well developed. 

 The cephalic element is singularly well developed, especially laterally. In fact I know no 

 other Octopod in which these ridges are so deeply flanged. When the latter are engaged, 

 it seems to me that the intake of water must be entirely prevented, as the base of the 

 funnel is so deep that there is no room for leakage at the sides. This condition is fore- 



'^ Since writing this description, which is based on the preserved specimen, I have seen the original 

 colour-sketch made when the animal was alive. The circular band of pale colour turns out to be a 

 circumoral ring of eight round white patches, each of which lies astride an arm. Between this ring 

 and the mouth, the web was bright reddish purple; peripherally and beyond the ring it was of an 

 intense bluish purple. This pattern and coloration are extremely vivid and arresting.
