CAMPANULARIA OCCIDENTALS sp. nov. 



Prof. S. F. Clarke mentions three species of Campan- 

 ularia from our Pacific coast. C. everta is recorded from 

 San Diego ; C. fusiformis from Vancouver Island and 

 Santa Cruz, while the locality of C. cylindrica is not 

 given. 



A Campanularia, which differs from these, was found 

 by me at Santa Barbara. 



The stem is irregularly branched and of light brown 

 color. It is ringed with moderate sized ferrules, with four 

 annulations at the basal joints. 



Hydrothecae are large, cup-shaped, slightly bulging at 

 the sides, with an entire, not dentiferous rim. 



Gonothecae large, oval, tapering from attachment to 

 truncated, distal termination. Orifice small, with slightly 

 raised lips. Sporosacs conspicuous, numerous, readily 

 seen through the sides of the gonothecae. 



Polypites have a brownish yellow color ; their tentacles 

 are slightly webbed. 



ATRACTYX.OIDES FORMOSA gen. et sp. nov. 



(PLATE IV, PIGS. 2, 3.) 



Stems solitary, erect, brownish, with masses of attached 

 algae on their external surfaces. The distal ends funnel- 

 shaped. Attached to a creeping stem. Each polypite 

 (hydranth) projects from a cup-shaped hydrotheca. 



Hydranth with single circle of tentacles ; mouth and in- 

 tratentacular region of whitish color. Hydrothecal base 

 annulated. 



The sporosacs arise from the base of attachment on sol- 

 itary, erect stems. Each male capsule has a central axis 

 (spadix) which has a green and yellow color. Near its
