The upper, meso- and lower lateral ridges were very distinct, while the thrust block was barely developed. The ascending mantle canal was thick and very obvious. The nectosac was narrow, and was further constricted in its mid-region. There were no signs of a mouth-plate.

in length, the thrust block had considerably enlarged and on its lower side there was a deep median furrow. Proximally the ascending mantle canal inflected slightly into the mesogloea and formed a small swelling. Distally, it gave rise to a very short pedicular canal that, on reaching the nectosac, branched off only the upper and lower radial canals. The lateral radial canals arose, asymmetrically, from the upper canal at some distance from the pedicular canal. Either lateral canal could arise first. There was a large muscle-free zone on the proximal part of the lower surface of the nectosac. In the preserved state the distal end of the nectophore was bent upwards such that the ostium of the nectosac opened on the upper side of the nectophore. The nectosac itself, again in the preserved state, tapered down from its slightly emarginated proximal end and was very narrow distally.

Distally they merged with the meso-lateral ridges, on a level with the ostium, and together they continued below the ostium on either side of a small, broad mouth-plate. The upper lateral ridges did not extend down to meet them proximally, only merging with the meso-lateral ridges. They curved inwards on the upper side of the nectophore and then out lateral again. At that point they became much less prominent, and the two branches that each gave rise to were often difficult to detect. The inner branches ran to the top of the ostium and the outer pair curved round to reach its lateral margin in the region of a small lateral ostial process.</paragraph>

) the thrust block had increased further in size and occupied almost half the length of the nectophore. It was broad, only tapering in its proximal third, and its proximal end was formed by a digitate process that frequently was bent upwards. The ascending mantle canal arose below the tapering section of the thrust block and continued to about half the height of the nectophore. Typically, as noted in other

species, it was slightly inflected into the mesogloea at its proximal end, and formed a small swelling. The nectosac, in its preserved state, was narrow and tapered down from its proximal end. As with the younger nectophore, its distal end was bent upwards so that the ostium of the nectosac opened on the upper side of the preserved nectophore. There was a large muscle-free zone on the proximal part of the lower surface of the nectosac that also spread, in the central region, for a short distance onto the upper surface. In the middle of this zone, the very short pedicular canal gave rise to only the upper and lower canals. Again the lateral canals arose asymmetrically from the upper canal, at some distance from the pedicular canal. These ran obliquely to the sides of the nectosac and then ran directly to the ostial ring canal.

The mouth-plate was now well-defined although remaining relatively small. It was either rounded or very slightly emarginated in the mid-line. The lower nerve tract could distinctly be seen running over it. The lateral ostial processes were reduced to short, narrow strips.</paragraph>

Although this description is based on a single, very incomplete specimen there are certain characters that establish the specimen as a new species. Firstly, the single bract is very distinctive. There is, of course, the possibility that this single bract did not belong to the species being described, but evenso the morphology of the nectophores is sufficient to distinguish the specimen as a new species. Thus, for instance, the mature nectophores were much smaller than those of all the presently described species. The longest nectophore of
