CAMPANULARIADJ1 : CAMPANULARIA. 109 



Couch's observation, that " the animal possesses the power of corru- 

 gating the whole," readily explains this variation in its appearance. 

 " This elegant microscopic sepcies is furnished with a delicate 

 joint or hinge, situated at the base of each little cup. This beauti- 

 ful contrivance is designed, I imagine, to enable this frail zoophyte 

 the better to elude the rude contact of the element by which it is 

 surrounded, by permitting it to bend to a force which it cannot re- 

 sist." A. H. Hassall. 



2. C. INTEGRA, " stem a single tube, filiform, creeping ; cells 

 on long slender twisted pedicles, campaniform, with the rim 

 entire; vesicles ?" W. W. Saunders.

" This species, which I believe to be new, differs from the pre- 

 ceding in having cells with the rim entire, and not serrulated, as in 

 C. volubilis. With C. syringa, the only other British species of the 

 genus which has a single tube for a stem, it can never be con- 

 founded : the ' denser corneous texture, cylindrical tubular cells, 

 and short pedicles' of (7. syringa are perfectly distinctive." J. Mac- 

 gillivray. 



In January, 1841, I received specimens of this species from Mr. 

 Saunders, named by him C. Icevis. In habit, texture, and size, it 

 resembles C. volubilis very exactly, but the rim of the cell is even 

 and smooth. The stalk is twisted like a screw, except at the top, 

 where there are four or five annuli, as represented in our figure. 

 Of his Camp, laevis Mr. Couch says, that the cells are " on long 

 slender unringed footstalks," but the even or ringed condition of the 

 stalk affords no specific character. " The polype," he adds, " has 

 eleven long and slender tentacula." 



3. C. INTERTEXTA, " texture spongy, composed of single 

 tubular fibres very much interwoven with each other, not 

 cells campanulate, apertures even.' 1 '' R. Q. Couch.
