CAMPANULARIA. Mihi. 

 Syn. Clytia, (pars) Lamaroux. (1812?) 



Campanirtaria, (pars) Lamarck. (1813?) 

 Eucope, {pars) Gegenbaur. (1856.) 



The bell is very deep for an Exostome. The digestive trunk 

 rather long, and remains long unprovided with labial appendages. 

 The radiate tube and sexual organs are each four in number, the 

 latter appear to be of the same type as those of Obelia and Epen- 

 thesis. The tentacula are more or less long and flexible, wanting 

 the stiff appearance visible in Obelia; they also want the re-en- 

 trant radix and have the type of bulb seen in Epenthesis. The 

 tentacula are either four or eight in number, perhaps sometimes 

 more but never numerous. The marginal capsules are eight in 

 number and contain each only one (?) corpuscle. 



The larvae are those Campanularidae which have usually creep- 

 ing stems, and deep cups for the digestive polyps. The rim of 

 these cups also is more or less deeply toothed, and the large vesi- 

 cles of the prolific polyps are annulate, either near the base or 

 throughout their whole extent. The deep character of the Medusa- 

 bell is exhibited at a very early stage of the bud, while it is yet 

 within the capsule, and it is never carried reverted as in Obelia. 



To this genus are probably referable all the Medusae from Cam- 

 panularidae like C. volubilis. Perhaps also such species as Thau- 

 mantias quadrata and T. seronautica of Forbes, and the Eucope 

 campanulata of Gegenbaur. 



Distribution. — British Seas, Coast of Holland, Mediterranean, 

 Charleston Harbor. 



CAMPANULARIA NOLIFORMIS, nov. spec. 

 PI. 11, Fig. 4. 



I have seen no specimen of this species which had attained 

 maturity, consequently the sexual organs have not been observed. 

 The young specimens possessing four tentacula, which have been 

 from time to time bred in my jars, exhibited a form of less alti- 

 tude than is represented by Gegenbaur in his E. campanulata, 

 the height of the bell in the present species being nearly equal 

 to its width. The diameter of the tentacular circle is not so much 

 less than that of the bell as to give the ovate appearance seen in 

 Gegenbaur's figure of the Mediterranean species. At this stage 

 the marginal capsules contain only a single corpuscle each, and 

 between every two of the four tentacula is a prominent bulb 

 representing the four additional tentacula of Eucope campanulata.
