llydrolda from Kergueleiis Island. 115 



Gonosome. Gonangia cylindrical above, with a flat summitj 

 tapering below towards the verj short peduncle, which springs 

 from the creeping stolon. 



Hah. Swain's Bay [Eaton) ; also Baffin's Bay. 



In the absence of any fuller knoAvledge of its gonosome, 

 this species (which is undistinguishable from a species obtained 

 last autumn in Baffin's Bay by H.M.S. 'Valorous') is only 

 provisionally referred to the genus Camjjanularia. 



Genus Hypanthea, n. g. 



Trophosome. Hydrotliecaj pedunculate, inoperculate, with 

 the walls enormously tliickened, and so encroaching upon the 

 cavity as to prevent the complete retraction of the hydranth. 



Gonosome. Gonangia enclosing fixed sporosacs. 



Type H. repens^ n. sp. 



Hypantliea rep)ens^ n. sp. 



Tropliosome. Peduncles about :j inch high, springing at 

 intervals from a creeping stolon, with a globular annulus just 

 below the hydrotheca, but otherwise smooth. Hydrotheca^ 

 obconical with very oblique margin, their cavity forming dis- 

 tally a shallow cup, Avhich is prolonged as a narrow cylindrical 

 tube backwards through the axis of the hydrotheca. 



Gonosome. Gonangia elongated, narrow, passing gradually 

 into a short peduncle which springs from the creeping stolon ; 

 colonies monoecious, the male gonangia surpassing in height 

 the hydrothecal peduncles, fusiform, opening on the summit 

 by a narrow circular orifice ; the female shorter than the male, 

 scarcely narrowing towards the distal extremity, where is a 

 wide orifice. 



Hah. Swain's Bay [Eaton). 



Hydkoida Gymnoblastea. 



? Genus Coryne, Ehrenb. 



Coryne conferta^ n. sp. 



Trophosome. Hydrocaulus about 1^ inch high, much and 

 irregularly branched, forming dense tufts ; stems and branches 

 distinctly and regularly annulated. Hydranth with about 

 twenty tentacles. 



Gonosome not known. 



Hah. Observatory Bay [Eaton). 



In the absence of the gonosome, it is impossible to ascertain 

 whether this is a Corynf or a Hyuconinc.
