This appears to be the first record of the occurrence of this species 

 in American waters. There are many specimens in the collection, but 

 all are from the same locality. 



Distribution. — Juneau, Alaska (Harriman Expedition) ; Great 

 Britain (Allman and Hincks) ; Lofoten Islands, Norway (Sars). 



Family BIMERID^^. 

 TropJiosome. — Hydranths with a conical or dome-shaped proboscis, 

 around the base of which is a whorl of filiform tentacles. 

 Gonosome. — Sexual products developed in fixed sporosacs. 



GARVEIA. 



Trophosotne. — Colony branched ; perisarc conspicuous. 



Gonosome. — Gonophores borne on distinct branchlets which have a 

 chitinous investment ending in a cup-like expansion just below the 

 gonophore.

 American waters. The specimens were fragmentary, making the 

 identification somewhat uncertain, although I have little doubt of its 

 correctness. 



Distribution. — Berg Inlet, Glacier Bay, Alaska. (Harriman Ex- 

 pedition.) Originally described from the British Coast. 



GARVEIA ANNULATA sp. nov. 

 (Plate XV, figs. I, 2.) 

 Trophosome. — Colony attaining a height oi 1^4 inches, consisting of 

 a number of closely aggregated and sparingly and irregularly branched 

 stems. Stems strongly and evenly annulated throughout, the perisarc 

 expanding distally into thin chitinous pseudo-hydrothecae which cover 

 the hydranth body nearly to the level of the tentacles. Hydranths with
