Calyptotheca wasinensis   (Waters,  1913) (Bryozoan)
Organism information awaits expert curation
Class: Gymnolaemata

Loosely encrusting. Zooecia usually short, convex, irregularly reticulo-punctate. Proximal lip of orifice often slightly raised or prolonged into a sort umbo or mucro; usually confined to some of the fertile zooecia; or extended proximally as a slight median ridge. Orifices and opercula (ordinary) mostly wider than long, but sometimes with the two diameters equal; a difference depending largely on the extent of the wide rounded sinus, which may be shallow or deep; (fertile) rather larger, wider than long, the sinus shallow. Avicularia very small, a lateral oral pair nearly always present (and no others) in the youngest colonies; in later stages also on lateral sutural lines, where they may be numerous. Ovicells, present in nearly all the specimens, globose, often with triradiate sutural lines.
