Organism information awaits expert curation
Class: Gymnolaemata

Size (Zooecium): Length 400 µ; breadth 260 µ.

Encrusting on shells. Zoaria (preserved in alcohol) yellowish brown. The size of the zooecia increases towards the margin of the colony. Zooecia arranged in longitudinal rows where the substratum is smooth. Mural rim thin and corrugated. Walls heavily calcified. Gymnocyst wanting. Cryptocyst well developed, descending distally, highly tuberculated, invade slightly the proximal portion of the zooecia. Opesia sub-triangular, proximal border frequently straight but may be arched in certain cases. Adventitious avicularia paired, placed at the sides of the zooecia distally. The slightly elevated rostra of the avicularia direct distally in a slanting manner towards the median line. The mandible triangular and pointed. Operculum membraniporine with a main marginal sclerite. Vicarious avicularia rare. The rostrum rounded distally more than half the length of the zooecium. Two condyles present, to which attach the ends of the strongly calcified basal sclerite of the mandible. No ovicell noticed. Spines wanting.
