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 zooecia 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 - l 5 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, off Heard Island, 7 5 fathoms, volcanic mud. Off Prince Edward 
Island, 80 to 150 fathoms. 
[Shetland (V), E. Forbes; Mediterranean, Milne-Edwards; Adriatic, Heller; Naples, 
Waters; Teneriffe and Canaries, d’Orbigny; Madeira, I. G. I.; Gulf of Florida, Smitt ; 
Port Jackson and Queensland, Haswell.] 
With respect to the Shetland locality 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. 
(2) Pustulopora proboscidioides, Smitt (sp.) (PI. IV. fig. 4). 
Entalophora probosidioides, Smitt, Florid. Bryoz., vol. i. p. 11, pi. iv. figs. 26, 27. 
Character. — Zoarium composed of elongated, forked, cylindrical branches, 0'7 to 1 mm. 
in diameter, constituted of about six longitudinal series of zooecia, almost entirely 
immersed, except a short, cylindrical, exserted portion with a circular orifice, about
