minute, stand a little from tbe surface, and are campanulate 

 with even truncated apertures. I have been unable to refer 

 this to any described species, and have therefore proposed 

 to call it intertexta as descriptive of its appearance. As the 

 peduncles are not ringed, it has been necessary to make a 

 slight alteration in Johnston's generic character for its re- 

 ception. 



CAMPANULARIA L-EVIS. R. Q. C. Arising from a 



creeping fibre ; cells distant on long slender unringed 



footstalks, campanulate with patulous even apertures. 

 PI. si. 



Hab. On stones and shells from deep water, Polperro. 



This species is by no means uncommon, but to be seen 

 must be examined in water while recent. It arises from a 

 creeping fibre at irregular intervals, the footstalk is long, 

 slender and dilates gradually into the cell ; the cell is cam- 

 panulate with a patulous and an even aperture, the polype 

 Las eleven long and slender tentacula. 



It somewhat resembles the Clytia tirnigera of Lamouroux 

 pi. 5, fig. 6, but the cell does not swell so much, nor is the 

 aperture so contracted as in that species. 



* * Stem composed of many parallel tubes. 



HORSE-TAIL CORALLINE. C. Verticillata. Poly- 

 pidom erect, tapering, branched ; cells od long toot-stalks, 

 arranged in a verticillate manner at regular intervals, 

 funnel-shaped, with notched rims. Vesicles ovoid, on 

 short peduncles, with small even apertures, rising from the 

 trunk.

Hab. On Pinna ingens, off the Dcadman; not common. 

 From one to seven inches high, stiff. The trunk is straight 

 and tapering, as are also the branches, which are long and 

 erecto-patent. The cells are bell-shaped with serrated rims, 

 on long annulated footstalks, ringed at their extremities and 

 plain about the middle, arranged in a verticillate manner at 

 regular intervals, and generally about five in a whorl. 



CAMPANULARIA DUMOSA. Climbing, hirsute ; cells 

 deeply tubular, nearly sessile ; apertures even, unarmed, 

 patent.
