208 Dr. W. C. M'Intosh on the Zoophytes of St. Andrews. 



Genus Campanulauia, Lamarck. 



Camfpanularia voluhilis, L. ; Hincks, Brit, H. Z. vol. i. 



p. 160. 

 Common ; on crabs, the stems of Sertularia argentea and 

 other zoophytes from deep water. It is a smaller and more 

 delicate species than C. verticillata. The shape of the cup 

 and the very distinct " spherical ring " below distinguish it 

 when the gonothecte are absent. 



Campanularia Hincksii, Alder ; Hincks, Brit. H. Z. 

 vol. i. p. 162. 

 Occasionally found on the stems oi Antennularia antennina 

 from the deep water of the bay. This species presents certain 

 variations. In some the stem is nearly smooth from the base 

 to the cup, where there are only a few slight twists ; in others 

 there are several distinct though irregular rings or twists at 

 the base, a few about the middle of the stem, and others at 

 the base of the calycle ; in almost all there is one very distinct 

 ring at the base of the latter, as Mr. Alder shows in his 

 figure *. There is also a peculiar hollow at the base of the 

 calycle ; but this cannot be called a ring. 



Campamdaria verticillata, L. ; Hincks, Brit. H. Z. vol. i, 



p. 167. 



Common in deep water. Many specimens were also found 

 in the stomach of Echinus esculentus from the laminarian 

 zone. 



Campanularia flexuosa, Hincks, Brit. H. Z. vol. i. p. 168. 



Not uncommon on the under surfaces of stones near low- 

 water mark. The peculiar zigzag form of the stem, with the 

 arms of the forks tending in opposite directions, together with 

 the short, broad, and smooth-edged hydrothecge, are character- 

 istic. The long pedicels of the hydrothecae had their central 

 smooth portions peculiarly flattened out, so as almost to 

 assume a fusiform aspect. 



Campanularia raridentata, Alder ; Hincks, Brit. H. Z. 

 vol. i. p. 176. 



Occasionally found on Antenrndaria antennina and other 

 zoophytes from the coralline ground. The form agrees in most 

 respects with the published description. The calycle is very 

 narrow and deep, with six to eight large teeth on the margin ;
