A HISTORY OF SUSSEX 



THECAPHORA 



CAMPANULARIID.S: 



1 1 . Clytia joknstoni, Alder. 



Colonies trailing over most objects, sea- 

 weed, stones, shells, wood, etc., throwing 

 up delicate partly-ringed stems terminating 

 in calycles with dentate margins. The 

 capsules are annulated and nearly always 

 borne upon the stolon ; gonozooid medusi- 

 form, minutely spotted with opaque white. 

 Very common, ranging from the beach to 

 moderately deep water. Hastings. 



12. Obelia geniculata, Linnaeus. 



This very common little species throws 

 up a zig-zag stem from a trailing stolon, 

 giving off at each bend a short branch 

 ending in a plain-rimmed calycle. Cap- 

 sules borne in the axils. The gonozooids 

 of Obelia have the peculiar habit of often 

 turning the swimming-bell inside out. 

 Common upon weed, stones, shells, etc., 

 upon the beach, and in deeper water. Has- 

 tings. 



. 1 3. Obelia ge/atinasa, Pallas. 



A very beautiful zoophyte suggestive of 

 a young and graceful birch tree. The 

 stem is compound and the branches are 

 usually given off in regular whorls. The 

 calycles are said by Hincks to be dentate, 

 but they are very difficult to define under 

 the microscope, the margin usually appear- 

 ing folded inwards. The capsules are deep 

 and vase-like and are formed in the axils. 

 A large and common species often growing 

 in very exposed positions on the shore. 

 From imperfect specimens preserved the 

 impression is gained that this species may 

 also occur with simple stolonic stem, over- 

 running other zoophyte stems. Hastings. 



14. Obelia /ongissima, Pallas. 



A species sometimes over a foot in 

 length, branching and tapering gradually 

 to the summit. The calycles are squarely 

 dentate ; capsules a little deeper than wide. 

 Amongst the trawlers' rubbish it may be 

 readily mistaken for a tangle of hair. 

 Common in the trawl from deep water.

15. Obelia dichotoma, Linnaeus.* 

 Hastings. 



1 6. Campanularia Integra, McGillivray.* 

 Hastings. 



17. Campanularia verticil/ata, Linnaeus. 

 Stem and main branches compound. 



Around the axis are given off simple, partly- 

 ringed branches, rather long and of equal 

 length terminating in dentate calycles. 

 The capsules are long and narrow-necked, 

 and occur on the compound parts of the 

 axis. Not uncommon in the trawl from 

 moderately deep water. Hastings. 



1 8. Campanularia flexuosa, Hincks. 



The notes and sketches at hand of this 

 species only allow of the remarks that the 

 calycles have a plain margin and are borne 

 upon rather long and well-ringed foot- 

 stalks, and that the capsules are an elongate 

 oval in form. Hastings. 



19. Campanularia neglecta, Alder.* 

 Hastings. 



20. Lovlnella clausa, Lov6n. 



A minute species throwing up long slender 

 stems ringed at the top, undulating else- 

 where, with deep elegant calycles of which 

 the scalloped margins are prolonged into 

 pointed segments which meet overhead, 

 closing the aperture. The chitine appears 

 to be of some thickness at the bottom of 

 the calycle, gradually thinning out towards 

 the top ; polypite with from twelve to 

 fourteen tentacles ; no capsules observed. 

 A single specimen associated with Perigs- 

 nimus repens upon Nucula nucleus. Coral- 

 line zone. Hastings. 



21. Gonothyrea graci/is, Sars. 



This zoophyte at first glance with the 

 hand-glass may be mistaken for Clytia 

 jobnstoni, but the calycles are much 

 deeper, the teeth of the margin longer and 

 sharper, and inclining inwards rather than 

 outwards. The stem just below the caly- 

 cle has four or five rings and again at the 

 base is ringed. Branches bearing a ter- 

 minal polypite are given off at about two- 

 thirds of the distance up the stems. Upon 

 Tutu/aria indivisa ; rare, Hastings. 



CAMPANULINIDJE 



22. Opercularella lacerata, Johnston. 



Zoophyte of very slender habit. It oc- 

 curs wound like fine thread around the 

 polyzoan Anguinella palmata, throwing up 

 short branching stems much annulated. 

 The calycles on short ringed footstalks 

 have the plain margin cut into segments 

 which meet over the centre, forming an 

 operculum. The polypite stretches out of 

 its calycle fully to the extent of the length 

 of the calycle. The species also occurs 

 upon sponges ; not general. Hastings.
