hollow where they are separated by small projection. One of the smaller specimens shows a minute 

 hectocotylised extremity to the third right arm, but it is too little developed to show any characteristic 

 features, and the groove leading up to it is but slightly indicated.

The Surface is practically smooth, except for wrinkles apparently due to the action of thespirit; 

 here and there on the body are traces of a shagreen-like pattern. 



The Colour is a very deep brown, almost black. The smaller specimens are even darker in 

 colour than the large one.

This species is well characterised by the very dark colouration, which suggested its specific name. 



Undetermined Octopod.

I have figured the radula (Textfig. 3) and am inclined to think it belongs to a species of 

 Tremoctopus.

The Body is slender and elongated, about four times as long as broad. It tapers gradually from 

 the anterior towards the posterior extremity, where it ends in a bluntly rounded point. The fin occupies 

 three-quarters of the length of the mantle ; its breadth is four-fifths of its length, and it is rhomboidal with
