Distribution. — Bering Sea (Jaderholm). 

 HALECID^ 



TropJiosome. — Hydrothec® arranged alternately; shallow sauc- 

 er-shaped, not deep enough to contain the contracted hydranths ; 

 margins even, often duplicated. Hydranths with conical pro- 

 boscis, surrounded by a single whorl of filiform tentacles. 



Gonosome. — Gonophores producing planulffi, (or medusoids, if 

 we are to include Dr. Torrey's genus Campalecium) usually dif- 

 ferent in the two sexes. 



Genus CAMPALECIUM 



"Tropliosome. — As in Halecium. 



"Gonosome. — Gonotheca, each with a blastostyle bearing sev- 

 eral medusoid gonophores ' '. ( Torrey ) . 



I have seen no type of this genus that Dr. Torrey has instituted, 

 nor has any other so far as I know. Dr. Torrey himself, has given 

 no more recent reference to it, but if his conclusions are correct, 

 it would seem that the characters are sufficient to make a new 

 genus.
