Calloporidae Norman, 1903

Colonies generally encrusting laminar sheets, rarely erect. Zooids often with extensive gymnocyst, an oval area including a cryptocyst which varies from minimal to extensive. Spines marginal to area absent or present, and may arch over the frontal membrane forming a protective cover. Interzooidal communication by septular pores or through pore-chambers. Avicularia variable in frequency and type: absent in some species, adventitious, interzooecial or vicarious in others. Ovicells range widely from barely detectable caps to prominent hyperstomial types.
