THE COAST OF CALIFORNIA. 



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

 given. 



A Campanularia, which diifers from these, was found 

 by nie 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. 



Hydrothecse 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 gonothecee. 



Polypites have a brownish yellow color ; their tentacles 

 are slightly webbed. 



Atractyloides FORMOSA gen. et sp. nov. 



(PLATE IV, FIGS. 2, 3.) 



Stems solitary, erect, brownish, with masses of attached 

 alffse 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 

 distal end the spadix is enlarged into a disk-shaped struct- 

 ure, and about midway in its length there arise lateral 

 branches from which originate the spermatic masses. The 

 proximal part of the spadix is connected with the inner 

 wall of the male capsule by a network of fibres represented 

 in fig. 3. At the distal end of the same organ the walls
