Most mature nectophores relatively large and flimsy, with typical heart-shaped appearance. Younger ones with distinct notch on lateral wings. Long ascending and descending mantle canals of approximately equal length. No pigmentation. Bracts in enantiomorphic pairs; broad, leaf-like, tapering toward the proximal end; lower surface flat, upper domed. Indistinct longitudinal ridge from distal, median point to about half the length of the bract. Distal point, in young bracts, bearing nematocysts. Bracteal canal in contact with lower surface of the bract for about one-third its length; distal part, inflected into the mesogloea; relatively long in youngest bracts but gradually shortens to a short process in mature bracts. Tentilla of unique form, with involucrum forming two lateral flaps, and inflated terminal process bearing two asymmetrically placed horns, one terminal the other sub-terminal. At some stage in its development, the cnidoband spirally coiled and containing only one kind of nematocyst, probably mastigophores. Desmonemes (?) present in the terminal process, particularly in the horns. Proximally attached palpons possess a palpacle although often lost before the palpon becomes fully developed in the preserved state.

) the ridge was quite broad and included two or three rows of distinctive ectodermal cells. The bract tapered down, proximally, more rapidly on the inner side than the outer to form a prominent protuberance at the proximal end. The length of the bracteal canal varied according to the age of the bract, but it was never seen to extend the whole length of the bract. In the youngest ones the canal stretched to about three-quarters the length of the bract, and the part enclosed within the mesogloea was twice as long as the part that ran along the lower surface. The former part was also much broader, and included a broad canal.

). In the preserved specimens the distal end of this tube was often curved to one side, and it was part that next began to elongate and to twist itself into 2–3 spirals to form the rudimentary cnidoband, which at this stage did not appear to be covered by a membrane. At the same time the involucrum, between the pedicle and the cnidoband began to differentiate. It formed a horseshoe shaped swelling with the two loose ends closely apposed. Simultaneously the terminal process began to form as a flattened irregular swelling at the distal end of the cnidoband, with two short, broad distal protuberances (

At the next stage of development the pedicle began to elongate considerably, becoming thinner walled, and with its central canal straightening out again, except at its distal end where, in the preserved state at least, it remained coiled.

Thus a thin-walled spherical cavity was formed that enclosed, usually in its proximal half, the cnidoband, and still retained the terminal and sub-terminal "horns". On one tentillum (

they grew the gonophores became more elongate with a wide pedicle, through which the gastrovascular cavity passed, occupying approximately a third of its length, and the subumbrella cavity extending distal to the sexual products, and was widely open. In its lining were four straight lateral canals. Further development saw a re-shortening of the pedicle, which still remained wide, and an enlargement of the subumbrella cavity; although the overall length of the gonophore only increased slightly. No nematocysts were noted on the gonophores.
