Hatching of , in the Tobaaquarium, Japand until the first-chamber stage. During our experiments, 19 animals hatched after relatively long embryonic periods ranging from 269 to 362 days. The embryonic periods of these animals are shorter than those of the specimens of . hatched in the Waikiki Aquarium at lower temperatures (22.2°C on average).

The Proposal of Ebenezer Howardposed of long mural parts of the septa and/or of the prismatic layer of the primordial rostrum. The first septum is prismatic; others are formed by the nacreous layer Type 2 (Mutvei, 1970), which in sections gives an impression of a granular structure; the mural parts of the septa show tabular nacre
