APPENDIX B

Citations and/or descriptions for all taxa listed here are given in Lazarus (1992), with the exceptions noted individually below.

Order Spumellaria Ehrenberg, 1875.

Collosphaeridae Müller, 1858.

Acrosphaera Haeckel, 1881.

Acrosphaera australis, Lazarus, 1990, pp. 712-713 (pl. 1, figs. 1-6).

Acrosphaera? labrata, Lazarus, 1992, pp. 793-794 (pl. 1, figs. 1-10).

Remarks: Forms seen are comparatively "late forms" with reduced bar widths and resemble to some degree the shell structure of an orosphaerid.

Acrosphaera? mercurius, Lazarus, 1992, p. 794 (pl. 1, figs. 11-16).

Siphonosphaera, Müller, 1858.

Siphonosphaera vesuvius, Lazarus, 1992, pp. 794-795 (pl. 2, figs. 1-8).

Actinommidae Haeckel, 1862, emend. Sanfilippo and Riedel, 1980.

Stylatractus Haeckel, 1887.

Stylatractus universus Hays, 1970, p. 215 (pl. 1, fig. 1); Lazarus, 1990, p. 717 (pl. 6, figs. 9-11).

Amphistylus Haeckel, 1881.

Amphistylus angelinus (Campbell and Clark) Chen, 1975, p. 453 (pl. 21, figs. 3, 4).

Remarks: In Lazarus (1992), the above two species were noted to be similar and were thought to represent an evolutionary lineage A. angelinus > S. universus, with the transition occurring in the middle Miocene. The forms seen here in the late Miocene and recorded under the name S. sp. cf. universus appear to be intermediate between S. universus and A. angelinus.

Druppatractus Haeckel, 1887.

Druppatractus hastatus Blueford, 1982, pp. 206-208 (pl. 6, figs. 3, 4).

Saturnalis circularis Haeckel, 1887, p. 131; Chen, 1975, p. 454 (pl. 24, fig. 2).

Spongodiscidae Haeckel, 1862, emend. Riedel, 1967.

Amphymenium Haeckel, 1881.

Pyloniidae Haeckel, 1881.

Prunopyle Dreyer, 1889.

Prunopyle titan Campbell and Clark, 1944, p. 20 (pl. 3, figs. 1-3); Lazarus, 1990, p. 717 (pl. 5, figs. 1-4).

Prunopyle hayesi Chen, 1975, p. 454 (pl. 9, figs. 3-5); Lazarus, 1990, p. 717 (pl. 5, figs. 5-8).

Prunopyle sp. "elliptical rings" (Pl. P1, figs. 1-4).

Remarks: The medium-large prunoid species is characterized by four to five elliptical shells, the outermost with clear larcoid gaps at the acute polar ends. Shell wall characteristics are similar to Lithelius nautiloides—fairly coarse, rounded pore and bar structure with rough, thorny surface. Shells are connected by numerous fairly stout radial beams. These are few-common in many late Miocene Antarctic samples, including Sites 745 and 746 on the Kerguelen Plateau.

Order Nassellaria Ehrenberg, 1875.

Suborder Spyrida Ehrenberg, 1847, emend. Petrushevskaya, 1971.

Desmospyris Haeckel, 1881.

Desmospyris rhodospyroides Petrushevskaya, 1975, p. 593 (pl. 10, figs. 27-29, 31, 32); Lazarus, 1992, p. 797 (pl. 7, fig. 4).

Dendrospyris "haysi" Lazarus, 1992, p. 797 (pl. 7, fig. 4).

Remarks: D. "haysi" in this report refers to the relatively fine-pored variant of D. rhodospyroides. It is not clear if this is really a distinct species or what the precise morphologic boundary between the two forms should be, but the D."haysi" form seems more characteristic for the late Miocene and the more robust D. rhodospyroides form for the older Miocene; thus, they were recorded separately here.

Triceraspyris Haeckel, 1881.

Triceraspyris coronata Weaver, 1976, p. 580 (pl. 2, figs. 4-5; pl. 6, figs. 8-9), Lazarus, 1992, p. 797 (pl. 7, figs. 5-9).

Antarctissa "bullet" (Pl. P1, figs. 5-8).

Remarks: This is a very small antarctissid with an indistinct cephalis and short thorax; height and width are approximately equal; it has a rough surface of small irregular pores and thorns. The base is always closed. This has a complex and not fully detailed set of internal beams. It is similar to A. cylindrica but smaller and shows even less evidence of a distinct cephalis either in outline or in cross-sectional view. There is no obvious apical spine. Some specimens have a furrow in the cephalic region, giving a faintly lobed appearance to the shell. These are few-common in late Miocene sediments of the Antarctic.
