ovate, with a small round terminal orifice. The wall varies in 

 thickness and may be slightly wavy. Aerocysts containing three 

 or four embryos were found on female colonics from Catalina. 

 Male gouothecae are smaller than female. 



Transitions between all the forms of hydrothecae can be 

 traced in the same colony. The typical form is different, how- 

 ever, in different localities. As a rule the Catalina specimens 

 have thicker walls than those from Pacific Grove, whose walls 

 are often quite thin; the San Diego material is intermediate in 

 this respect. 



G. everta may be distinguished from Glytia compressa, which 

 it closely resembles, by the gonosome only. The gouothecae 

 have a much narrower aperture and the gonophores are fixed 

 sporosacs. 



Campanularia fascia, sp. now 



PI. IV. Fig. 38. 



Trophosome. Height of longest stem, 45 mm. Branching irregularly and 

 profusely, forming a coarse, shrubby tuft. Stem and branches polysiphonie; 

 ultimates alone mouosiphonic. Perisare thin throughout, wrinkling easily. 

 Ultimates wavy or ringed, never with more than two hydranths. Shorter 

 hydranth stalks with 8-10 rings; longer with 9-11 at base and 5-8 immedi- 

 ately below hydranth, with wavy interval. Hydrothecae less than twice as 

 long as broad, cylindrical in distal half, tapering gradually to narrow base. 

 Rim with 11-12 moderately sharp teeth. Hydranth with 20-24 tentacles. 



Gonosome absent. 



Distribution. Pt. Loma, San Diego, Cal.; hard sand bot- 

 tom. Covered with Galycella syringa. 



Campanularia fusiformis Clark. 



C.fusiformis, Clark, Trans. Conn. Ac, 1876. Ill, p. 254. 



Distribution. Point Reyes Peninsula, growing on Bimeria 

 annulata; Dillon's, Cal., on Sertularia anguina. Vancouver I., 

 on iS'. anguina. Between tides. 



This sj ies resembles V. urccolata closely. The hydrothecae 



are deeper, narrower, with fewer and blunter teeth. The gono- 

 theca often has a long neck. It may be sessile or raised on a 

 peduncle with five or six annulae. Gonophores present July 7, 

 1898, and August 10, 1892.
