Tentacle-bulbs large pyramidal, without ocelli and without nettling warts. Tentacles tapering, 

 shorter than bell-height when contracted, their proximal parts with scattered nematocysts, 

 and distal two-thirds with ring-like nettle-batteries. 4 straight, slender radial-canals without 

 an axial-canal above the stomach. Gonads and tentacle bulbs )ell()vvish-brown, other pans 

 colorless. From Todohokke and Hokkaido, Japan. ll\droid unknown. It is probabl)- an 

 Arctic form. 



It is distinguished from .9. respleiulcns and S. brachygaster by having no ocelli, and from 

 iV. apitula bv having no axial-canal and by its bluntly rounded apex. Its nearest relative is 

 .9. jlnmuica, with which, indeed, it may prove to be identical.

Krumbach gives a detailed account of Elmthcria. Unfortunately I have not seen his 

 paper and am unable to review it.

Binder gives a good description of the hydroid from the Atlantic coast of France, and 

 Richters records it from Helgoland, German Ocean.
