Small nectophores that, when mature, have a relatively short, broadly truncated basal process. A pair of small lateral ostial processes and, usually, a pair of patches of ectodermal cells on the lower lateral sides of the velum. No other patches present. Preserved specimens have a pair of furrows on the ostial side of the nectophores. The descending mantle canal is longer than the ascending one. Small rhomboidal bracts with more or less welldefined transverse and median ridges. The upper side is truncated; the distal margins formed by the transverse ridge, the proximal ones extremely vague. A pair of patches of ectodermal cells on the distal facets of younger bracts, but lost in the fully mature ones. Palpons are attached baso-laterally so that the proboscis and opening are at an angle of c. 135° to the stem.

On the ostial side of the nectophore, a pair of ill-defined ridges was present on the inner sides of the axial wings that continued down to above ostial level and demarcated a deep gutter between them. Also on the ostial side was a pair of lateral furrows that ran obliquely out and up from the lateral margins of the ostium. They may have been preservation artefacts, but their presence was quite constant.

They were very vague in the upper half of the nectophore, but more prominent basally before they petered out just below the lower level of the nectosac. In the younger nectophores they tended to approach each other more closely, while in the larger ones the mesogloea on the inner sides was thickened with the narrow hydroecial furrow running between them.</paragraph>

The radial canals had typical courses, the upper and lower being straight, the laterals first curving out and diagonally upwards, then down to join the ostial ring canal. The long descending mantle canal extended down into the basal process, although its distal portion was very vague. The ascending canal was shorter and extended up to the mid-ostial region. The pedicular canal gave rise to all four radial canals. Above each lateral radial canal, just before it joined the ring canal there was a small patch of ectoderm cells. Another pair of patches was present on the lower lateral sides of the velum. These patches were often extensive in the younger nectophores, but in the mature ones were smaller and more rounded.</paragraph>

in width. They were roughly rhomboidal in shape, with the younger ones resembling a diamond, the older ones more elongate. In the preserved state they were covered in pimples, but that was probably an artefact. The lower surface was flat, while the upper one was thickest centrally. There was a more or less well-defined transverse and median ridge; often with both appearing as just a rounded processes. Spherical nematocysts were found spaced out in a single row along the median ridge and, occasionally, onto the ridge demarcating the lower side of the distal facet. Also, on the younger bracts it was sometimes possible to see much smaller nematocysts arranged along the transverse ridge, but they had been lost in the mature ones.

Occasionally it was found that the truncation narrowed and stretched down to the proximal end of the bract. The bracteal canal arose close to, but not at, the proximal end of the bract and stretched up to its mid-length. It was terminated by a large ovoid swelling that was inflected into the mesogloea. The connection between this and the canal itself was sometimes very difficult to see. On the younger bracts there was a pair of patches of ectodermal cells on the distal facets, either side of the median ridge. These gradually disappeared such that there was no trace of them on the mature bracts.</paragraph>

However, the angle at which the proboscis region projects out from the main body of the palpon is quite different, being 135° in the former and 90° in the latter. The differences in the morphology of the bracts of these two species, as is discussed below, should, in association with the above, clearly distinguish the two.
