Diagnosis
IDENTIFICATION. Body small to medium (about 2-3 cm tall), with heart-shaped rhopaliar niche ostia, scalpel-shaped pedalia, and epaulette-like phacellae. The velarial canals are 2 per octant, with the adperradial typically being much less branched than the adinterradial. The South Western Australian form of C. xaymacana has statoliths of a similar shape to C. rastonii, i.e., rounded pentagonal shape, broad and dome-shaped, or thick, kidney-bean-shaped, depending on one’s perspective. The tentacular nematocysts of the southwestern Australian form are of two types: 1) large club-shaped microbasic euryteles, range 26-37 x 12-15 and 2) small oval isorhizas, 9-12 x 5-7 The tentacular euryteles of the Caribbean form are about the same size (29-33 x 12-15 but have a much finer tubule; isorhizas could not be found.
