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 hydrothecae 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. Sertulariidse. 
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 hydro thecae so far as examined. 
Sertularella ruyosa, 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.
