Figure 8. Typical Trilobatus quadrilobatus and intergradation with Trilobatus sacculifer. A–K, Trilobatus quadrilobatus (d'Orbigny, 1846); L–P, Trilobatus sacculifer (Brady, 1877). A, B, E, F, G–K, ODP Site 871, Limalok Guyot, Marshall Islands, equatorial Pacific 3H/03/60–62 cm (A, E–I, K, umbilical view; B, detail of wall texture, including spine holes, infilled pores, broadened interpore ridges; J, detail of wall texture and imperforate lip developed on primary aperture); C, D, GLOW-3, south-west Indian Ocean (C, umbilical view; D, spiral view). L–P, ODP Site 871, Limalok Guyot, Marshall Islands, equatorial Pacific 3H/03/60–62 cm (L–P, umbilical view; for L note slight chamber flattening compared with I–K). Scale bars = 100 Lm, except for close-up images B and J, where scale bars = 20 Lm.
