Halicornaria furcata, Bale, var. intermedia, Bale, Biological 
Results “Endeavour,” 1, 1, 1914, Addendum, p. 1; zd., 
Briggs, Rec. Austr. Mus., x, 10, 1914, p. 298, pl. xxv, fig. 3. 
Several monosiphonic, dichotomously branched colonies, 
the largest 285 mm. in height, are associated with Aglao- 
phenia tasmanica, on which this variety always occurs as 
an epizoon. Bale first recorded it from Oyster Bay, 
Tasmania, where ‘‘a large colony of it was found accom- 
panying Aglaophenia tasmanica, but whether it had com- 
menced as a parasite on that species, after the fashion of 
so many of its congeners, it was impossible to determine, 
the stems being matted together with other growths.”’ 
This variety was also found in association with specimens 
of A. tasmanica from 100 fathoms, seven miles east of Cape 
Pillar, Tasmania. The present specimens are quite similar 
to the colony originally described.
