Genus Pulvinulina, Parker and Jones.
Pulvinulina truncatulinoides, d'Orbigny sp.

Rotalina truncatulinoides, d'Orbigny, 1839, Foram. Canaries, p 132, pl. ii, figs. 25–27

R. micheliniana, d'Orbigny, 1840, Mém. Soc. Géol. France, sér 5, vol. iv, p. 31, pl iii, figs 1–3.

Pulvinulina truncatulinoides, d'Orb. sp., Rhumbler, 1900, in K. Brandt's Nordische Plankton, heft 14, p. 17, fig. 16

P. micheliniana, d'Orb. sp., Millett, 1904, Journ. R. Micr. Soc, p. 500.

Although there seems to be reason for supposing that d'Orbigny's two works, to which reference is made above, were published almost simultaneously, yet the actual dates of publication differ, and therefore, according to the rule of priority, the better-known specific name, P. micheliniana, unfortunately must lapse.

This species has been already recorded for the South Pacific, and notably at sta. No. 169. It is not uncommon in our series.

Pulvinulina crassa, d'Orbigny sp.

Rotalina crassa, d'Orbigny, 1840, Mém. Soc. Géol. France, ser 5, vol. iv., p. 32, pl. iii, figs. 7, 8.

Pulvinulina crassa, d'Orbigny sp., Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 329, pl. lxxiv, fig. 1. Rhumbler, 1900, in K. Brandt's Nordische Plankton, heft 14, p. 17, figs. 12, 14, 15. Millett, 1904, Journ. R. Micr. Soc., p. 500.

This species has been recorded from the east coast of New Zealand (sta. 169). It is rather rare in our series.

Pulvinulina canariensis, d'Orbigny sp.

Rotalina canariensis, d'Orbigny, 1839, Foram. Canaries, p. 130, pl. i, figs. 34–36.

Previously recorded from the South Pacific. It is rare in our sounding.

This species is not uncommon in the present series.

It has occurred in the South Pacific at depths between 17 and 275 fathoms (“Challenger”). Egger also records it from Western Australia.

Pulvinulina schreibersii, d'Orbigny sp.

Rotalina schreibersii, d'Orbigny, 1846, Foram. Foss. Vienne, p. 154, pl. viii, figs. 4–6.

This handsome species is not uncommon in our series.

Brady notes this form as being almost peculiar to the South Pacific.
