formed like that of an Octopus rather than like that of an Eledone, 

 as shown in Verrill's figure." In the light of our present knowledge 

 that even relatively slight differences in the structure of the hecto- 

 cotylus are important in distinguishing species, there is evidently 

 available here a sufficient diagnostic character to separate the two 

 forms. A new name therefore seems expedient for the Kermadec 

 species.

Sketches are now given of one of the curious hood-shaped suckers 

 which appear along the distal regions of the arms, and also of a 

 portion of the gladius (figs. 1-3). 



The gladius of this species, as shown by a few fragments extracted 

 from the poorly preserved paratype (S. S. B. 410), is exceedingly 

 slender and consists of little but the narrow rhachis. The wings 

 are narrow and set very obliquely, so that the ventral concavity is 

 unusually narrow and deep. They finally terminate in a very 

 small, delicate, spoon-shaped cone, which is supported by a small,
