l86 NUTTING [l68] 



phore is borne on a pedicel which resembles those of Garveia, having 

 a distinct expanded collar a short distance below the hydranth. 



Distribution. — Sitka Harbor and Yakutat, Alaska, abundant (Harri- 

 man Expedition) ; Shetland Island, Scotland (Allman). 



This beautiful species bears considerable resemblance to Euden- 

 drium annulatutn Allman, especially in its gonosome which Allman 

 describes as follows: "The gonophores are grouped in clusters, con- 

 sisting of from eight to twenty egg-shaped bodies attached around the 

 axis of gonoblastidea, which are of moderate length."' 



Were it not for a peculiar character of the trophosome, i. e., the ex- 

 panded pseudo-hydrotheca investing the body below the tentacles much 

 as in Garveia, there might be some suspicion that S. vaginatum and 

 E. annulatum are synonyms, particularly in view of the fact that both 

 were described from the Shetland Islands. 



It also seems not improbable that Eudendrium pygmcEiim Clark' 

 may be another synonym of B. vaginatum, as Clark's description of 

 the gonosome agrees well with the gonosome described above. If 

 this be true, it is also likely that the dried stems described by Clark 

 from Santa Cruz, California, will be found to belong to this same 

 species. 



Family TUBULARID^E. 

 Trophosome. — Hydranths large, with a basal whorl of filiform ten- 

 tacles and a distal set of closely crowded shorter filiform tentacles. 



Gonosome. — Reproductive elements developed in sessile medusae 

 borne in clusters just above the basal tentacles and producing actinules 

 instead of planulas. 



TUBULARIA. 



The only genus included in the family in the sense here used. 



TUBULARIA HARRIMANI sp. nov. 

 (Plate XVI.) 



Trophosome. — Stem usually unbranched, attaining a height of i J^ 

 inches, irregularly and sparingly annulated and increasing in size from 

 the proximal to the distal end, but more rapidly on the basal portion ; 

 a marked constriction some distance below the hydranth body ; stem 

 canaliculated between the constriction and the hydranth. Hydranth 

 with forty to fifty basal tentacles and about twenty in the distal set. 



Gonosome. — Gonophores borne in about twelve very long and 

 densely crowded racemes, which are supported by long, tentacle-like
