APPENDIX
This Appendix contains a taxonomic list of all planktonic foraminifers cited in the text, listed in the distribution charts (Tables T2, T3, T4, T5), and illustrated in Plates P1, P2, and P4 and arranged in alphabetic order by genus and species. Comments are included for some species to clarify the taxonomic concepts used in this study and to report significant morphological features observed in the assemblages. The generic and specific concepts follow Luterbacher (1964), Boersma and Premoli Silva (1983), Berggren and Norris (1997), Olsson et al. (1999), and references therein.
Acarinina Subbotina, 1953.
Acarinina mckannai (White) = Globigerina mckannai White, 1928.
Acarinina nitida (Martin) = Globigerina nitida Martin, 1943.
Acarinina strabocella (Loeblich and Tappan) = Globorotalia strabocella Loeblich and Tappan, 1957.
Acarinina subsphaerica (Subbotina) = Globigerina subsphaerica Subbotina, 1947.
Globanomalina Haque, 1956, emended.
Globanomalina imitata (Subbotina) = Globorotalia imitata Subbotina, 1953.
Globanomalina pseudomenardii (Bolli) = Globorotalia pseudomenardii Bolli, 1957.
Globanomalina ehrenbergi (Bolli) = Globorotalia ehrenbergi Bolli, 1957.
Igorina Davidzon, 1976.
Igorina albeari (Cushman and Bermudez) = Globorotalia albeari Cushman and Bermudez, 1949.
Igorina albeari "chubby"
Remarks: The specimens included in this group seem to be an intermediate form between Igorina pusilla and I. albeari. The inferred relationship with I. pusilla is supported by having similar compressed chambers and strongly curved and slightly depressed sutures on the spiral side. On the other hand, this form resembles I. albeari in having a strongly biconvex test, a circular profile, and a low interior marginal aperture with an arch extending toward the peripheral margin but differs in lacking the peripheral keel. This morphotype has previously been reported and illustrated by Berggren and Norris (1997) as I. albeari from ODP Hole 758A.
Igorina pusilla (Bolli) = Globorotalia pusilla pusilla Bolli, 1957.
Igorina pusilla "high trochospire"
Remarks: This group includes the specimens of I. pusilla characterized by having a high trochospire. Similar morphotypes are illustrated by Olsson et al. (1999) from ODP Hole 761B (Wombat Plateau, Indian Ocean).
