Figs 16–21 in Redescription of Strombidium coronatum (Leegaard, 1915) Kahl, 1932 (Ciliophora, Spirotricha) based on live observation, protargol impregnation, and scanning electron microscopy

Figs 16–21. Strombidium coronatum, Irish Sea specimens (16–18, scanning electron micrographs; 19–21, protargol impregnation, micrographs of several focal planes were stacked, using the computer program CombineZP from Alan Hadley). 16 – ventrolateral view; 17 – left lateral view showing uniquely shaped peristome, which is roughly triangular in outline and almost flat, extending in the sagittal plane. The extrusomes insert in short oblique rows anteriorly to the girdle kinety; note that some of them are just ejected (arrowhead); 18 – posterior cell portion showing the sharp, longitudinal ridges that have already been illustrated in the original description by Leegaard (1915); 19 – left lateral view of an early divider; 20 – dorsolateral view of an early divider; 21 – ventrolateral view. AP – apical protrusion, BM – buccal membranelles, CM – collar membranelles, DC – distended cell surface, EX – extrusome attachment sites, GK – girdle kinety, MA – macronucleus, OP – oral primordium, VK – ventral kinety. Scale bars: 40 µm (16), 20 µm (17, 19–21), and 10 µm (18).
