| Diagnosis | Stolonal colonies composed of stolons creeping on substratum and giving rise to sock-shaped hydrothecae, adnate to substratum to a varied degree. Adnate part of hydrothecae provided with striae on dorsal side; striation highly variable. Hydrothecal aperture circular, rim even. Cnidome composed of two kinds of nematocysts, small and large ones. Coppinia composed of a set of firmly adpressed gonothecae surrounded by a fence of long defensive tubes usually curved towards the centre of the gonothecal mass in such a way that they constitute a nest or corbula. Defensive tubes forked or unforked, provided with distal, circular aperture. Gonotheca tubular, basally truncated and with a distal, unraised, circular aperture, usually on a slightly raised, cone-shaped part. Eggs remaining on gonothecae, immersed in a sort of nourishing mass. |
