Stn Low 45 , several polysiphonic stems, up to 60 mm high, with male gonothecae, on bryozoans. Diagnosis. Polysiphonic, irregularly branched stems, up to 70 mm high. Branches originating from hydrophore of primary hydrotheca. Hydrothecae alternately arranged in one plane. Hydrotheca at the end of long, free hydrophore distinctly directed adcaudally and provided with pseudodiaphragm. Hydrotheca distinctly widening distally; rim everted. Up to sixth-order hydrothecae. Female gonotheca bivalve-shaped, both abcauline and adcauline walls of similar development. Aperture all distal part, from the widest part upwards. Male gonotheca of similar shape, but much smaller.

Hydrothecae alternately arranged in one plane and placed at the end of long hydrophores (Fig. 11 A–D); ratio between adcauline length of hydrophore and diameter at diaphragm 1.1–1.4.
