Fig. 4. Haimeicyclus haimei (Chapuis and Dewalque, 1853). A. Juvenile specimen IPUM−Sic.93 with 48 septa on polished base (herein in distal view). B. Proximal view of IPUM−Sic.94 attached to the bivalve shell incrusted by juvenile specimen IPUM−Sic.94a with 12 septa (arrows). C. Etched, initial portion of the corallum IPUM−Sic.68 with voids corresponding to position of protosepta (arrows mark position of six septa on half of corallum). D. IPUM−Sic.88 incrusted by serpulid tubes and juvenile scleractinians, in distal (D1) and proximal (D2) views in conventional photographs, and on SEM micrographs (proximal views D3, D4) showing enlargement of twelve septate juvenile (two septa of additional cycle marked with smaller arrows). E. IPUM−Sic.9191 in oblique view (E1) with juvenile (?bud) attached laterally (E2, enlargement). All from Sinemurian Black Limestones, Longi, Sicily.
