JAVAUX AND SCOTT: BENTHIC FORAMINIFERA FROM BERMUDA v. 1808 Archaias spirens de Montfort, 1808, p. 190, 48e genre. v. 1808 Helenis spatosus de Montfort, 1808, p. 195, 49e genre. v. 1808 Ilotus rotalitatus de Montfort, 1808, p. 199, 50e genre. v. 1816 Orbiculina adunca (Fichtel and Moll). Lamarck, 1816, pl. 468, figs. 2a-c. v. 1822 Orbiculina angulata (Fichtel and Moll). Lamarck, 1822, p. 609, no. 2 v. 1822 Orbiculina numismalis Lamarck, 1822, p. 609. v. 1928 Archaias angulatus (Fichtel and Moll). Cushman, 1928, p. 218, fig. 9. This species lives in reefs of many tropical and subtropical areas. It is abundant in Bermuda lagoons and reefs, Florida-Bahamas outer reefs and patch reefs, Jamaica backreefs and reefs, St. Lucia open bay with reef patches, in reefs of Cuba, Barbuda and Panama, and in reefs of the Belize Shelf where it forms an “Archaias-Asterigerina dominant” assemblage characteristic of high turbulence area. Genus ASTERIGERINA d'Orbigny, 1839a Asterigerina carinata d'Orbigny, 1839a Figure 2.8 and 2.9 v. 1839 Asterigerina carinata d'Orbigny, 1839a, p. 118, pl. 5, fig. 25; pl. 6, figs. 1, 2. Bock, 1971, p. 54, pl. 19, fig. 12; pl. 20, fig. 1. This large biconvex species is commonly found in Bermuda outer reefs (high turbulence). It is also reported in backreefs and reefs of Florida-Bahamas, Jamaica, St. Lucia, Cuba; and in the forereefs, backreefs and reefs (hight turbulence areas) of Belize Shelf. Genus BORELIS de Montfort, 1808 Borelis pulchra (d'Orbigny), 1839a Figure 2.10 and 2.11 v. 1839 Alveolina pulchra d'Orbigny, 1839a, p. 70, pl. 8, figs. 19, 20. v. 1884 Alveolina melo (part) (not Fitchell and Moll), Brady, 1884, p. 223, pl. 17, figs. 14, 15. v. 1930 Borelis pulchra (d'Orbigny). Cushman, 1930, p. 55, pl. 15, figs. 9, 10. Bock, 1971, p. 37, pl. 14, fig. 7. This species is found in low abundance in lagoon and reefs of Bermuda and Florida-Bahamas. Genus BROECKINA Munier-Chalmas, 1882 Broeckina orbitolitoides (Hofker), 1930 Figure 2.12 and 2.13 v. 1930 Praesorites orbitolitoides Hofker, 1930, p.149, pl. 55, figs. 8, 10, 11, pl. 57, figs. 1-5, pl. 61, figs. 3, 14. Bock, 1971, p. 35, pl. 13, fig. 15. Hallock and Peebles, 1993, p. 284, pl. 2, figs. 5, 6. This large species is found in lagoons of Bermuda and Florida-Bahamas. Genus CARPENTERIA Gray, 1858 Carpenteria proteiformis Goës, 1882 Figure 2.15 v. 1882 Carpenteria balaniformis Gray var. proteiformis Goës, 1882, p. 94, pl. 6, figs. 208-214; pl. 17, figs. 215-219. v. 1884 Carpenteria proteiformis Goës. Brady, 1884, p. 679, figs. 8-14. Bock, 1971, p. 62, pl. 23, fig. 4. This species is found in backreefs and reefs of Bermuda. It has probably been overlooked in many areas because of its unusual morphology. Genus CIBICIDES de Montfort Cibicides refulgens de Montfort, 1808 Figure 2.16 and 2.17 v. 1808 Cibicides refulgens de Montfort, 1808, p. 122; Barker, 1960, p. 190, pl. 92, fig. 7-9. This species is present in Bermuda caves and lagoonal reefs. It is not reported in other areas although it is figured in Barker’s report of Atlantic expedition. Genus CLAVULINA d'Orbigny, 1826 Clavulina tricarinata d'Orbigny, 1839a Figure 2.14 v. 1839 Clavulina tricarinata d’Orbigny, 1839a, p. 111, pl. 2, figs. 16-18. Bock, 1971, p. 11, pl. 2, fig. 14. Steinker, 1980, p. 135, pl. 2, fig. 2. This agglutinated species occurs in low abundance in nearshore and lagoons of Bermuda. It is also reported in nearshore, lagoons, and patch reefs of 13
