Figure 1 in Revision of the north-eastern Atlantic and Mediterranean species of the genera Herentia and Therenia (Bryozoa: Cheilostomata)

Figure 1. Herentia hyndmanni (Johnston, 1847). (A, B) PMC.R.I.H.B-3c, Ionian Sea; (C, E, F) NHM 1899.5.1.1154, off Northern Ireland; (D) lectotype, NHM 1847.9.16.156, off western Scotland. (A) Kenozooidal ancestrula and first autozooecium; while the ancestrular gymnocyst is bored and damaged, we consider the central hole (arrow) as representing the remnant of an extremely reduced opesium; note the spine bases on the distal orifice margin of the autozooecium, the central pair of spines is already covered by the calcified rim encroaching the distal orifice margin; (B) ancestrula and early astogenetic colony; note the presence of a central hole in the ancestrula and the relatively proximally positioned avicularia in the autozooecia; (C) autozooecia and an ovicellate zooecium at the colony growth margin; note that in this and the other photos showing ooecia the vertical component, i.e. the distally raised ooecium hood, is understated; (D) general aspect of unbleached colony; (E) close-up of orifice and avicularium; (F) ovicellate zooecium; note slightly narrower condyles compared to those of autozooecia. Scale bars: 100 mm (A); 200 mm (B–D); 50 mm (E, F).
