FIGURE 6. SEM micrographs of Smittina imragueni n. sp. A, aspect of colony fragments (right, holotype SMF 40005; left, paratype SMF 40006). B, cross-section through a branch, showing thick secondary calcification and different profiles of zooidal chambers (paratype SMF 40007). C, interior view of primary orifice and suboral avicularium (SMF 40007). D, autozooids showing a relatively early developmental stage of the peristome (SMF 40010). E, secondary orifice with an intermediately developed peristome (SMF 40006). F, immersed secondary orifice late in ontogeny; note the vertical orientation of the avicularium (SMF 40007). G, ancestrular area (paratype SMF 40008). H, transition between encrusting and erect growth (paratype SMF 40009). Scalebars: A, 2 mm; B, G, 500 µm; C, E, 100 µm; D, F, H, 200 Μm.
