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, Hahcium, &c. The speci- 

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

 that the male gonothecaj 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.

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 hych-othecse hke those on the beautiful 

 southern H. tenellum, Hincks. 



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

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

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 hydrothecaj 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 srround.
