WEST COAST HYDROIDS 23 



Distribution. — Yakiitat and Sitka, Alaska (Nutting) ; Santa 

 Catalina Island, San Francisco, Cal. (Torrey) ; Port Renfrew, 

 Ucluelet. 



In this case, as in many other cases later in the work, I have 

 followed the principle that because two species or two genera 

 intergrade, it does not follow that the two should be combined 

 under one name. Dr. Torrey has often taken the opposite view, 

 and has here combined Garveia and Bimeria, both genera insti- 

 tuted by Wright and used by most authors since that time, under 

 the name Bimeria. Even if some of the sporosacs of this species 

 are entirely covered with chitin, it does not necessarily follow, 

 that hence the whole genus Garveia should be combined with the 

 genus Bimeria. 



IGAEYEIA FORMOSA (Fewkes) 



Perigoniimis formosu.<i Fewkes, New Invert, of Cal. Coast, 1889, p. 6. 

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



Distribution. — Santa Cruz, Cal. (Fewkes). 



Fewkes' description of this is not sufficiently clear to decide 

 very definitely as to the genus to which it belongs. It is evidently 

 not a Perigonimus. Torrey in his list has placed it with Bimeria^ 

 but he includes Garveia with Bimeria in any case. It seems to 

 me that it is probably a Garveia, and I have so placed it.
