Character. — Zoarium composed of long, straight, alternate, furcate, cylindrical 

 branches, 0'4 to 0"9 mm. in diameter, constituted usually of four longitudinal alternate 

 series of zocecia which are exserted for about one-third of their length, the exserted tube 

 curving outwards nearly at a right angle and constituted mainly of a peristomal produc- 

 tion, ringed, thin, not punctate, with an entire circular orifice about 0'15 mm. in 

 diameter; surface elsewhere finely punctate. Ooecia consisting apparently of a terminal 

 expansion, or of one situated close to a bifurcation. 



Habitat. — Station 151, ofi" Heard Island, 75 fathoms, volcanic mud. OS" Prince Edward 

 Island, 80 to 150 fathoms.

With respect to the Shetland locahty assigned to this species in the Brit. Mus. Cat. 

 on the authority of E. Forbes, as its occurrence in that locality is not noticed either by 

 Mr. Norman or by Mr. Hincks as a British form, and, moreover, is omitted by Professor 

 Smitt in Lists of Scandinavian or Arctic Polyzoa, it is highly probable that some mistake 

 has arisen. It would appear to be a Mediterranean and Atlantic form, extending as far 

 south as the Kerguelen region.

Character. — Zoarium composed of elongated, forked, cylindrical branches, 07 to 1 mm. 

 in diameter, constituted of about six longitudinal scries of zoa?cia, almost entirely 

 immersed, except a short, cylindrical, exserted portion with a circular orifice, about
