Plate 6: This cross section of a later neurula stage (35h pf, 18°C) reveals that the coelomic cavities of the first mesodemial segment are still comparatively spacious. Medial myoge- nic and lateral coelothelial mesodemi cells are easily distinguished. The medial cells diffe- rentiate into myocytes displaying irregularly an-anged myofilaments at this stage already. The two diverticula of Hatschek are seen on this cross section. They are still continuous with the archenteron. Note also the relatively voluminous
