This is a very striking species. I saw many specimens 

 brought up in the dredge on the " Albatross," when 1 had the priv- 

 ilege of being on board her, during her expedition in the Sagami 

 and Suruga Seas. It is very hirge, hiter measurements showing 

 it to be about 25 cm. long and 12 cm. broad, and about as 

 much in lieight. While it was one of the commonest among 

 the spoils of the " Albatross," I had never seen one, or a 

 piece of one, brought up by the long line, on which we depended 

 mostly for deep-sea forms. It was only by his diligence and 

 resourcefulness that Kuma Aoki succeeded at last, in June 1Ö05, 

 in bringing up some specimens of this species with a dredge 

 at the same place in which he obtained Ewjpniastes eximia 

 Théel. 



While it is such a striking form, it is one of the hardest 

 forms to identify, owing to two circumstances : (1) the total 

 absence of any calcareous spicules and of the calcareous ring, and 

 (2) the difficulty of preserving tlie specimens in anything 

 like the original shape. The skin comes off almost entirely in
