FIGURE 4. Hincksina neptuni (Jullien in Jullien & Calvet, 1903) n. comb. A. Overview of lectotype with auto- and ovicellate zooecia (MOM INV-22462). B. Slightly oblique view on two autozooids (MNHN IB-2008-1999). C. Oblique view on the two fan shaped, oral spines (top), the distalmost pair of mural spines proximal to these (centre), and two pairs of more proximally positioned mural spines (bottom) (MNHN IB-2008-1999). D. Incompletely developed zooids at colony growth margin, note the relatively thin vertical zooecial margins from which the mural and oral spines will develop by epithelial folding during later ontogeny. E. Ooecium (lectotype, MOM INV-22462). F. Avicularia with mandibles still in place (lectotype, MOM INV-22462). Scale bars: A, D, 200 µm; B, F, 100 µm; C, E, 50 µm.
