BIMERIDyE 



ATEACTYLOIDES FOEMOSA Eewkes 



Atractyloides formosa Fewkes, New Invert, from Cal. Coast, 1889, p. 5. 



This species, when it was described by Fewkes, was given a 

 new generic as well as a new specific name. As he did not give 

 the generic characters separately, I have referred to it among 

 the species only. 



Genus BIMERIA 



Trophosonie. — Colony branched, invested with a conspicuous 

 perisarc. Hydranth fusiform, hypostome conical. Perisarc cov- 

 ering the base of the tentacles. 



Gonosome. — Sporosacs, covered with perisarc, arising from the 

 stem or branches. 



BIMEEIA FEANCISCAXA Torrey 

 Bimeria franciscana Torrey, Hydroida of the Pacific Coast, 1902, p. 28.. 

 Distrihution. — San Francisco Bay (Torrey). 



BIMERIA GRACILIS Clark 

 Bimeria gracilis Clark, Hydroids of the Pacific Coast, 1876, p. 252. 

 Bimeria gracilis Torrey, Hydroida of the Pacific Coast, 1902, p. 8. 



Distribution. — San Diego (Clark). 



BIMERIA ROBUSTA Torrey 



Bimeria robusta Torrey, Hydroida of the Pacific Coast, 1902, p. 29. 



Distribution. — San Pedro, Cal. (Torrey) ; San Juan Archi- 

 pelago. 



Some fragments in the San Juan material answer to the de- 

 scription given by Dr. Torrey, but as in his material, there were 

 no gonosomes present. The perisarc extended well up on the 

 base of the tentacles in all cases. 



Genus GARVEIA 

 Trophosome. — Colony branched. Perisarc conspicuous. Hy- 

 dranths fusiform. 



Gonosome. — Sporosacs borne on distinct branchlets, more or 

 less invested with perisarc, which regularly is confined to the 

 branchlets only.
