Hydrothecacompletely free from internode, very delicate and often crumpled in basal part,curved outwards, widening towards aperture, with three well-developed mar-ginal teeth, one adcauline and two latero-abcauline. No internal teeth. Oper-culum of three valves. Floor similar to that of Sertularella (Fig. 8A, B, D;Fig. 9 left). The second colony (8/24-B) is in a very fragmentary condition, consistingmainly of small pieces of hydrocladia. There is, however, a stem of 110 mmwith a few stumps of hydrocladia left; it is fascicled for the first 45 mm. Anotherportion of stem 46 mm long bears regular pairs of hydrocladia as in 10 hydrocladia branch up to five times. This colony is fertile and bears.
