Exumbrella devoid of radial ridges. Mesoglea rather thin, comparatively thickened at margin, accommodating a belt of chordal cells on which the tentacles insert. Over 300 tentacles, inserted at 3–5 superimposed levels, apparently not forming distinct rows or clusters; solid, core composed of a single row of chordal cells; proximally constricted, leaving tear drop-shaped scars when shed; blunt-ended to pointed distally, and there devoid of adhesive pads; nematocysts evenly dispersed in epidermis, except for the distal tip, where they are comparatively crowded. Manubrium cross-shaped (four perradial lobes are distinguishable), except proximally where it assumes an octagonal shape at the origin of the radial canals; relatively long, though devoid of a peduncle, and extending somewhat beyond the bell margin; mesenteries absent; mouth square, with four simple lips provided with ciliated cells in the epidermis. Eight radial canals with rounded cross sections connect to the broad ring canal, elliptical in cross section, longer axis oral-aboral; centripetal canals absent. A conspicuous nematocyst ring on lower side of umbrella margin. Velum extremely broad and strong. Eight slender, elongated gonads, in four perradial pairs; one pair conFned to each manubrial lobe. Eight small, shortstalked, interradial statocysts with single, spherical statoliths; one statocyst in each octant. Cnidome: almost spherical stenoteles [(7–8) × (6–7) µm], tear drop-shaped microbasic euryteles [(4–7) × (3– 5) µm], and atrichous isorhizas (ca 2 µm); the capsules occur in both tentacles and the marginal ring. Color: umbrella translucent, with white to yellow epidermal spots at junction of radial canals with the ring canal.</paragraph>
