ITydrosome.—Only a few hydrocauli of this very small form were found. 
They are about 0°1 mm. in length by 0°06 mm. in breadth, and arise from a 
filamentous hydrorhiza. The hydrocauli are much shorter than in Campanulina A. 
and strongly ringed throughout their length. The hydrothece are 0°25 mm. in 
length by 0°15 mm. in diameter and apparently not so flexible as in A. 
Their margins are cleft to form about the same number of opercular flaps. 
There are about fifteen tentacles, 0°08 mm. in length. 
Gonosome.—Unknown.
