with descriptions of new Species. 1 79 



AUman, Esq. of Bandon has supplied me with abundant speci- 

 mens of a Campanularia from the coast of Ireland, which, to my 

 no small delight, has proved to be identical with Mr. Boswell's 

 species. A careful examination of these has fully convinced me 

 that this elegant form can be referred to none of the species 

 hitherto described as British. 



The remarkable peculiarities of internal structure are in them- 

 selves sufficiently distinctive. The double cup and the inner 

 casing of the medullary pulp are, so far as I know, unique. But 

 there are also other important characters which separate it from 

 C. Integra, its nearest ally. 



Fi'om the creeping stem of C. caliculata, which spreads, in 

 the specimens I possess, over one of the red sea-weeds, rise 

 at intervals crenated pedicles, bearing campanulate cells, which, 

 instead of being wide and basin-shaped like those of C. 

 integra, are rather in the form of a wine-glass. They are per- 

 fectly transparent and have the rim entire. Within is a second 

 cup of most graceful form, resembling an inverted hand-bell, in 

 which the body of the polype is lodged. This inner cup, the 

 walls of which ai-e continuous above with those of the cell itself, 

 is produced below into a tubular sheath, which encases the me- 

 dullary pulp throughout its entire length, and is crenated hke 

 the stalk. I have likened the inner cup to an inverted hand- 

 bell, and the resemblance is veiy striking ; for one segment of 

 the crenated sheath, mentioned before, is always included within 

 the outer cup, so as to represent the handle of the bell. 



The stalks which support the cells are very constant in their 

 characters. Amongst a great number examined, I have met with 

 scarcely any variation. They are somewhat thick in proportion 

 to their length, and are composed for the most part of about 

 nine or ten crenations, of which the one immediately below the 

 cell is always the smallest. Like the cells they are double 

 throughout, as is also the creeping stem. Throughout the en- 

 tire structm-e there is an inner envelope which immediately sur- 

 rounds the animal substance, and which is very distinctly visible 

 when the polype and the pulp have perished. 



Mr. Boswell, who had the pleasure of examining the polypes 

 when alive, informs me that they are " exceedingly opaque and 

 the tentacles rather small." 



A mere description, however faithfully it may give the cha- 

 racters, can hardly do justice to the beauty of this interesting 

 species. This want however is supplied by Mr. Tuffen West's 

 expressive drawing, than which nothing could be more true to 

 the original (Plate V. B.). 



Hab. Discovered by Mr. R. S. Boswell in Pegwell Bay. Near 

 the Old Head of Kinsale, County Cork, R. AUman, Esq.
