164 CAMPANULARIID^E. 



sharply carinated, truncate above, with a plain circular 

 orifice, below somewhat abruptly attenuated, and attached 

 by a short, smooth stalk. 



I HESITATE to identify the C. l<evis of Couch with this 

 species, although it may possibly be nothing else. He 

 speaks of " the footstalk " as unringed, and dilating gra- 

 dually into the calycle. The latter part of this description 

 has no application to C. Integra, nor to any other Cam- 

 panularia that I know of, while the pedicel of the present 

 species has always two or three very marked rings at its 

 upper extremity, and is distinctly twisted below them. 



When the capsules, which are profusely developed and 

 of most elegant form, are present, there are few prettier 

 sights of the kind than a colony of this species. 



Hab. Donmouth (Macgillivray) : Hastings (Saunders) 

 (it seems to be common on the south-eastern coast) : Ilfra- 

 combe, on red weed; Filey (T. H.) : on roots of Lamina- 

 rise and Ascidise, low-water mark, Bamborough (J. A.) : 

 Wick (C. W. P.) : Belfast Bay. 



[C. Integra occurs in immense profusion on weed from 

 Hamilton Inlet, Labrador, taken up in 15 fathoms. The 

 capsules are in great abundance and of very large size, 

 and the whole aspect of the specimens betokens a con- 

 genial habitat. The calycles have their chitinous walls 

 greatly thickened.]
