APPENDIX

Albatrossidium sp.

Remarks: Rare pterocorythid fragments encountered in the Site 1128 material show great similarity with species illustrated in Sanfilippo and Riedel 1992, pl. 1, figs. 1, 2, 7, 8, 12, 13, 18, 19; pl. 2, figs. 1, 2, 7; pl. 6, fig. 3a, 3b (Pl. P2, fig. 21).

Amphisphaera minor (Clark and Campbell) Sanfilippo and Riedel, 1973, p. 486, pl. 1, figs. 1-5; pl. 22, fig. 4 (Pl. P2, fig. 6).

Amphymenium splendiarmatum Clark and Campbell, 1942, p. 46, pl. 1, figs. 12, 14 (Pl. P2, fig. 18).

Aphetocyrtis rossi Sanfilippo and Caulet, 1998, p. 18, pl. 2, figs. 8, 9, 12, 13; pl. 7, figs. 1-9 (Pl. P2, figs. 1-3).

Axoprunum pierinae (Clark and Campbell) group Sanfilippo and Riedel, 1973, p. 488, pl. 1, figs. 6-12; pl. 23, fig. 3 (Pl. P2, fig. 7).

Botryocella cribrosa (Ehrenberg) group Hollis et al., 1997, p. 53, pl. 4, figs. 1-4 (Pl. P1, fig. 18).

Remarks: The Oligocene samples contain sporadic, very rare cannobotryids, which probably all belong to one species and are superficially similar to early members of the Botryopyle dictyocephalus Haeckel group, except that they have a postcephalic tube at the base of the cephalis.

Botryostrobus cf. B. hollisi O'Connor, 1997b, p. 105, pl. 1, figs. 9-12, pl. 5; figs. 1-4 (Pl. P1, figs. 13-15).

Remarks: The morphotypes encountered at Site 1128 differ from B. hollisi in that their general shape is cylindrical (as in O'Connor, 1997b, pl. 1, fig. 12, pl. 5, fig. 1) and in that the abdomen frequently has more than two transverse rows of pores. The forms described by O'Connor (1997b) are from lower Miocene deposits in New Zealand.

Botryostrobus joides Petrushevskaya group, Petrushevskaya, 1975, p. 585, pl. 10, fig. 37; Hull, 1996, p. 137, pl. 4, figs. 5, 6, 20 (Pl. P1, figs. 3, 12).

Remarks: Included in this group are forms with 6-10 segments. The thorax is truncate conical with three to five rows of pores. The features of the cephalis and thorax are obscured by a "cockscomb" or frilled ornamentation connecting the apical horn and vertical tube, which extends downward covering the surface of the cephalothorax and sometimes including the abdomen and the first postabdominal segment. The apical horn varies in length from equal in length to twice the length of the cephalis. Morphotypes have been observed where the horn is bladed, sharply pointed, or consists of a crown of thorns or a flared apical tube. The forms in Hole 1128C are rather similar to Spirocyrtis sp. A described by Hollis et al. (1997, p. 56, pl. 4; figs. 33-35) from southwest Pacific DSDP Site 277. Members of the B. joides group differ from Spirocyrtis proboscis O'Connor (1994, p. 341, pl. 2, figs, 1-4, pl. 3, figs. 13-16) in having smaller thoracic pores, no bandlike distinct lumbar stricture, and in having post-thoracic segments that are rounded rather than angular and from Botryostrobus rednosus Caulet (1991, p. 535, pl. 3, figs. 9, 10) in having a less robust shell and by having three to six rows of pores on the postabdominal segments in transverse rows. The resemblance of these taxa is striking, and the differences in morphological features may be ecologically controlled.

Carpocanistrum spp. (Pl. P1, fig. 22).

Remarks: Forms included here vary in the degree of the longitudinal alignment of the thoracic pores, degree of constriction of the mouth, and presence or absence of peristomial teeth.

?Cyrtocapsa osculum O'Connor, 1997a, p. 75, pl. 1, figs. 15-17; pl. 2, figs. 1, 2; pl. 8, figs. 3-10 (Pl. P2, figs. 19, 20).

Remarks: Moderately rare two-segmented forms without any trace of a third segment and a very constricted mouth are questionably tabulated as C. osculum. These forms are present only in Sample 182-1128C-13H-2, 130-132 cm.

Cyrtolagena laguncula Haeckel, 1887, p. 1451, pl. 75, fig. 10 (Pl. P2, fig. 4).

Dictyoprora urceolus (Haeckel) Nigrini, 1977, p. 251, pl. 4, figs. 9, 10; Hollis et al., 1997, p. 56, pl. 4, figs. 36, 37 (Pl. P2, figs. 10-12).

Remarks: Specimens encountered at Site 1128 resemble Dictyoprora gibsoni described by O'Connor (1994, p. 338, pl. 1, figs. 5-8; pl. 3, figs. 4-7) but differ in having a more inflated thorax, an abdomen that is elliptical to inflated medianly, and varying in its degree of lateral compression in the sagital plane. The transverse section of the abdomen of the forms, herein identified as D. urceolus, varies from elliptical to circular but is not as markedly compressed as that described by O'Connor (1994) in D. gibsoni.

?Eucyrtidium spinosum Takemura, 1992, p. 746, pl. 5, figs. 5-8 (Pl. P1, fig. 4).

Remarks: Takemura (1992) separates E. spinosum from E. cheni (Takemura, 1992, p. 746, pl. 4, figs. 1-4), based on the length of the apical horn. In E. spinosum, the apical horn is approximately twice the length of the cephalis, whereas in E. cheni, it is shorter than the length of the cephalis. The forms herein are questionably assigned to E. spinosum because the apical horn is often broken.

Heliodiscus inca Clark and Campbell, 1942, p. 38, pl. 3, fig. 17; Hollis et al., 1997, p. 53, pl. 4, figs. 1-4 (Pl. P1, fig. 6).

Hexacontium sp. A (Pl. P2, fig. 17).

Remarks: Spherical cortical shell, thick-walled with a rough surface and hexagonally framed rosette-shaped pores, rather regular in size and arrangement. Six external spines, mutually perpendicular, short, pronouncedly bladed near the bases. Medullary shell double, joined to the cortical shell by six strong bars colinear with the external spines.

Remarks: The specimens encountered herein are similar to T. bianulus in all respects except that the cylindrical abdomen only has one annular part instead of two. In this respect, the Site 1128 forms are more like Eucyrtidiidae gen. et sp. "rocket" illustrated by Petrushevskaya and Kozlova 1972, p. 547, pl. 28, figs. 2, 3 and Eucyrtidium sp. cf. E. "rocket" in Ling 1975, p. 731, pl. 12, fig. 19.

Ebridians (marine planktonic silica-secreting organisms commonly found in cold or temperate waters) were found to be rare to few in the siliceous sediments cored at Site 1128 (Pl. P1, figs. 23, 24). Their fossil record goes back to the Paleocene, although most genera and species are recorded from the Eocene and Miocene. The species Ammodochium ampulla Deflandre, 1934, is present at Site 1128. Perch-Nielsen (1975) recorded this species in assemblages from the sub-Antarctic southwest Pacific, DSDP Sites 277, 281, and 283. A. ampulla was originally described from the upper Eocene diatomite of Oamaru, New Zealand.
