Canda pecten Thornely, 1907

( Fig. 2F )

Colonies are erect, planar, biserial, and dichotomously branching. On the frontal side of branches autozooids face obliquely away from the branch axis, while on the abfrontal side is a disconnected series of triangular vibracula, each with a setiform mandible that curves round the frontal side. Short transverse rootlets from vibracular chambers connect adjacent branches at intervals. Autozooidal opesiae taper proximally and characteristic frontal avicularia curve obliquely across branches near a bifurcation ( Fig. 2F ). There is no scutal spine. The species is principally Indo-West Pacific in its distribution ( Harmer, 1926; Tilbrook, 2006).
