With larger embryos the sac pro- jects as shown in Fig. 57 A, but is still in close contact with the frontal membrane. Two sacs with large and apparently advanced embryos are free from the membrane except for a distal attachment proximal to the operculum (Fig. 57 B), and an empty shrivelled sac has a similar attachment (Fig. 57 C). In this last specimen the frontal membrane is mainly convex, but shows a well-marked depress

In this last specimen the frontal membrane is mainly convex, but shows a well-marked depression where the sac may be presumed to have rested at an earlier stage. This depression is, however, not to be seen in the specimen shown in Fig. 57 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
