Figure 5. Comparison of early astogeny in (A–C) Alecto compacta (Norman, 1867) [5Oncousoecia dilatans (Johnston, 1847)] (NHM 11.10.1.64) and (D–F) Microeciella suborbicularis (Hincks, 1880), two species formerly considered synonymous. (A) Ancestrula and first budded zooids; (B) ancestrula with short distal tube; (C) large protoecium with tiny pseudopores around perimeter (best seen top right); (D) fan-shaped young colony; (E) ancestrula with long distal tube; (F) protoecium with a few, non-perimetrical pseudopores and two larger, enigmatic punctures or borings (left). Scale bars: 500 mm (D); 200 mm (A); 100 mm (B, E); 50 mm (C, F).
