A) was the fact that the upper lateral ridges ended, distally, well above ostial level and without dividing. Both the upper and lower lateral ridges were well-defined while the vertical laterals were less so, although they clearly joined with the other two ridges. There was a prominent lateral spot on either side of the nectophore just distal to the vertical lateral ridges and as the lateral radial canals passed over the lateral apices of the nectosac they were considerably thickened. The lateral ostial processes were not prominent at this stage, and the canal running through them was ill-defined. However, they bore nematocysts measuring c.

Distally, the upper lateral ridges turned inwards and ran directly toward the midline, before turning back toward the ostium and becoming much less distinct and gradually petering out. The lower ones continued to the ostium. Just distal to the vertical lateral ridge there was a small patch of ectodermal cells. The axial wings increased further in size and formed a pair of extensive lobes. The thrust block remained relatively small but now took on its characteristic form, consisting of two rounded lobes, on the upper side of the nectophore, behind which where two smaller digitate flaps.

in maximum width. They possessed two pairs of lateral cusps, with the distal pair being almost symmetrical, while the proximal pair were distinctly asymmetrical, with the cusp on the inner side being considerably more distal than the other. The distal end of the mature bracts was pointed and formed a right-angle. Proximally the inner side was thickened. The bracteal canal arose on the upper side of the bract and, once it had passed over to the lower side, remained in contact with the lower wall of the bract for most of its distance. However, distally it narrowed considerably and ran obliquely through the mesogloea to end below a large patch of cells, including nematocysts, that was raised above the upper surface of the bract just prior to its distal end. In the youngest bracts, this cluster of cells was formed into a ball that projected beyond the distal tip of the bract. A small circular patch of ectodermal cells was present in the mid-line on the upper side of the bract, usually approximately on a level with the more distal of the proximal pair of lateral cusps. This was not always to be seen on the younger bracts.

B, D, 45). Although, for many, the cnidoband was of about the same length, the degree to which the lure was developed varied considerably. Only a few had the fully developed red-pigmented lure (

The relative sizes of the cnidoband and the lure varied during the development of the tentillum. At the very youngest stage (

D), in its preserved state, it consisted of a highly contracted pedicle, with the relatively wide gastrovascular canal concertinaed. The cnidoband formed a hemispherical partial covering to an inflated cavity, with the very small stalkless photophore projecting out from the other side. The earliest stage photographed in life (

E). Only at the final stages in the development of the tentillum did the photophore, with its covering of fluorescent material, greatly increase in size and the vacuolated stalk considerably elongate. At all stages of development the tip of the stalk could be flicked through strong contractions of the stalk itself. One young specimen, with only sixteen nectophores, was found to have retained the larval tentacle at the posterior end of the siphosome (

It was flicked in a similar manner to the adult one, through contractions of the stalk, and the photophore consisted of a small hemispherical protuberance from close to its distal end.

On reaching the subumbrella this canal initially gave rise to five radial canals and, after a short distance, three of these divided so that eight canals ran down to the ostial ring canal. Whether this was also the case for the male gonophores could not be elucidated. After preservation the egg turned a dark brown colour and no superficial structures could be seen. However, in life there were 11 bluish ribbon-like structures which connected with the region that was presumed to contain the nucleus (
