ZOOPHYTES. 27 



bay. Most of the specimens show a ring or two on the stem 

 above the calycles. 



Halecium Beanii, Johnston ; Hincks, Brit. H. Z. vol. i. p. 224. 

 Not uncommon in the coralline region, attached to other 

 zoophytes and to the tests of Ascidians. Young examples have 

 piles of little cups on the hydrothecse like those on the beautiful 

 southern H. tenellum, Hincks. 



Halecium labrosum, Alder ; Hincks, Brit. H. Z. vol. i. p. 225. 

 From the deep-sea lines of the fishermen. Bather rare. 



Fam. 8. Sertulariidae. 



Genus Sertularella, Gray. 



Sertularella polyzonias, L. ; Hincks, Brit. H. Z. vol. i. 

 p. 235. 



Abundant in the deep water of the bay, generally attached 

 to the roots of other corallines. All the specimens seem true 

 to the description of the species ; at least there is no tendency 

 to wrinkles in the hydrothecaa so far as examined. 



Sertularella rugosa, L. ; Hincks, Brit. H. Z. vol. i. p. 241. 

 Common under stones near low-water mark, and thence to 

 deep water, on seaweeds, Flustra foliacea, &c. 



Sertularella tenella, Alder; Hincks, Brit. H. Z. vol. i.p. 242. 



In profusion on Sertularia abietina and other zoophytes from 

 the coralline ground. 



Genus Diphasia, Agassiz. 



Diphasia rosacea, L. ; Hincks, Brit. H. Z. vol. i. p. 245. 



Abundant in deep water on other corallines, such as Hydr- 

 allmania falcata, Thuiaria thuja, Halecium, &c. The speci- 

 mens are large and luxuriant. Mr. Hincks is right in stating 

 that the male gonothecae have eight longitudinal ridges, and 

 not six as Dr. Allman says. 



Diphasia tamarisca, L. ; Hincks, Brit. H. Z. vol. i. p. 254. 

 Not uncommon in deep water attached to shells and stones.
