Hydrothecae borne on short, smooth pedicels; deeply campanulate, tapering basally, and there provided with a transverse, thing diaphragm; walls parallel, widening distally; rim well-marked, aperture closed by a conical operculum composed of 13–15 elongate, triangular flaps, not connected between them, and folded either inwards or outwards. Nematothecae given off irregularly among the hydrothecae; globular, borne on moderately-long pedicels, aperture distal, circular.

. Nevertheless, there are several morphological characters which allow their specific differentiation. The latter is distally ramified, its nematothecae are borne on both the hydrorhiza and hydrothecal pedicels, and the hydrothecal aperture is closed by an operculum composed of 8–10 flaps. None of these features were observed in our material; moreover, the opercula of our hydrothecae are composed of a higher number of flaps.
