Subgenus Dentalina, d'Orbigny.
Nodosaria (Dentalina) consorbrina, d'Orbigny sp.

Dentalina consobrina, d'Orbigny, 1846, Foram. Foss. Vienne, p. 46, pl. ii, figs. 1–3. Nodosaria (D.) consobrina, d'Orbigny sp., Brady, 1884, Rep. Chall., vol. ix, p. 501, pl lxii, figs. 23, 24.

A single specimen was found in our sample.

Nodosaria (D.) consobrina, d'Orb. sp., var. emaciata, Reuss.

Dentalina emaciata, Reuss, 1851, Zeitschr. d. deutsch. geol. Gesellsch., vol. iii p. 63, pl. iii, fig. 9.

Nodosaria (D.) consobrina, d'Orb. sp., var. emaciata, Reuss, Brady, 1884, Rep. Chall., vol. ix, p. 502, pl. lxii, figs. 25, 26.

This slender variety is more common than the type form in the present series. It has already been recorded from the South Pacific.

Nodosaria (D.) filiformis, d'Orbigny.
Plate III, fig. 5.

Nodosaria filiformis, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 253, No. 14. Flint, 1899, Rep. U S. Nat. Mus. (1897), p. 310, pl. lv, fig. 6.

This species is distinguished by its long, slender, recurved test, with oval segments. It is not uncommon in the present series. Some of the specimens have a bulbous commencement, whilst others have the extremity attenuated and finely pointed. The latter variation agrees with the form figured by d'Orbigny under the name of Dentalina elegans.

N. (D.) filiformis has been recorded from the South Pacific, but not from the neighbourhood of Great Barrier Island.

Nodosaria (D.) farcimen, Reuss sp.

Dentalina farcimen, Reuss (after Soldani), 1863, Bull. Acad. Roy. Belg., ser. 2, vol. xv, p. 146, pl. i, fig. 18.

Nodosaria farcimen, Soldani sp. Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 309, pl. lv, fig. 5.

One specimen of this universally distributed form found in our series.

Nodosaria (D.) soluta, Reuss sp.

Dentalina soluta, Reuss, 1851, Zeitschr. d. deutsch. geol. Gesellsch., vol. iii, p. 63, pl. vii, fig. 4.

Nodosaria soluta, Reuss sp, Flint, 1899, Rep U.S. Nat. Mus. (1897), p. 310, pl. lvi, fig. 3. Millett, 1902, Journ. R. Micr. Soc., p. 516.

This species is not uncommon in the present series. Its occurrence at 110 fathoms off Great Barrier Island is in accordance with Dr. Brady's remark that in the South Pacific this species affects shallower water than in other localities. N. (D.) soluta has been recorded from the “Challenger” station 169 by Dr. Brady.

Nodosaria (D.) pauperata, d'Orbigny sp.

Dentalina pauperata, d'Orbigny, 1846, Foram. Foss. Vienne, p. 46, pl. i, figs. 57, 58.

Nodosaria (D.) pauperata, d'Orb. sp., Brady, 1884, Rep. Chall., vol. ix, p. 500, woodcuts, figs. 14 a-c.

This species is fairly typical, and occurs frequently in our series.

Nodosaria (D.) roemeri, Neugeboren sp.

Dentalina roemeri, Neugeboren, 1856, Denkschr. d. k. Akad. Wiss. Wien, vol. xii, p. 82, pl. ii, figs. 13–17.

N. (D.) roemeri, Neug. sp., Brady, 1884, Rep. Chall., vol. ix, p. 505, pl. lxiii, fig. 1.

This form has been recorded by Brady as being chiefly found in the North Atlantic, at depths of less than 1,000 fathoms. It is therefore the more interesting to meet with it in the present sounding off Great Barrier Island at 110 fathoms, where it is not uncommon.

Nodosaria (D.) obliqua, Linné sp.

Nautilus obliquus, Linné, 1767, Syst. Nat., 12th ed., p. 1163, 281; 1788, Ibid, 13th (Gmelin's) ed, p. 3372, No. 14.

Nodosaria (D) obliqua, Linné sp, Brady, 1884, Rep. Chall., vol. ix, p. 513, pl. lxiv, figs. 20–22. Goës, 1894, K. Svenska Vetenskaps-Akad. Handl., vol. xxv, No. 9, p. 70. pl. xii, figs. 691–696; pl. xiii, fig. 697.

This is one of the most noteworthy species of Foraminifera in the present series, and is here very abundant. It is not uncommon to find specimens reaching the extraordinary length of 9·5mm. Some of the shells are rather irregular in growth, and tend to become sinuous

N. (D.) obliqua has been previously recorded from “Challenger” station 169, near the present locality.

Nodosaria (D.) obliqua, L. sp., var. vertebralis, Batsch var.
Plate III, fig. 5.

Nautilus (Orthoceras) vertebralis, Batsch, 1791, Conchyl. des Seesandes, p. 3, No. 6, pl. ii, figs. 6 a, b.

Nodosaria vertebralis, Batsch sp., Bradv, 1884, Rep. Chall., vol. ix, p. 514, pl. lxiii, fig. 35; pl. lxiv, figs. 11–14.

– 95 –

N. obliqua, L sp., var. vertabrahs, Batsch, Goës, 1894, K. Svenska Vetenskaps-Akad. Handl., vol. xxv, No. 9, p. 70, pl. xiii, figs. 698, 699.

That this form is only a variety of N. obliqua is clearly demonstrated by the present series of specimens. Indeed, it is somewhat difficult to satisfactorily separate the variety from the species in some cases.
