In 1910 Lahillia luisa was described from the Antarctic Upper Senonian (11), and L. larseni Sharm. & Newt. sp. from the Antarctic Tertiary (12). Woods (13) in 1917 described a Lahillia from the Upper Senonian of New Zealand under the name Mactra? This determination was rectified by me in 1920 (14). In 1907 v. Ihering (15) wrote, “The genus Lahillia, which is well developed in the Upper Cretaceous and Palaeogene faunas of Patagonia and Chile, has not been found in New Zealand,” and “Lahillia seems not to have reached New Zealand.” One sees that his cautious manner of speaking was justifiable. Gastropoda. Arrhoges Gabb. Arrhoges haastianus O. Wilck. 1922. Arrhoges haastianus O. Wilckens, The Upper Cretaceous Gastropods of New Zealand, N.Z. Geol. Surv. Pal. Bull. No. 9, p. 9, pl. 2, figs. 5–7. An internal cast with strongly weathered surface. The determination would scarcely be possible were the shell not well preserved at the margin of the outer lip, so that the outline of the wing can be seen. Locality.—Shag Point, loc. 592.

No. 9, p. 11, pl. 2, figs. 8, 9. A sculptured internal cast of 3–4 whorls, reaching down to the beginning of the outer lip. Locality.—Shag Point, loc. 592. Protodolium O. Wilck. Protodolium speighti (Trechmann sp.). 1917. Neritopsis speighti C. T. Trechmann, Cret. Moll. from N.Z., Geol. Mag., n.s., dec. 6, vol. 4, p. 300, pl. 19, figs. 12–15. 1922. Protodolium speighti Trechm. sp.: O. Wilckens, Upp. Cret. Gastrop. N.Z., N.Z. Geol. Surv. Pal. Bull. No. 9, p. 18, pl. 4, figs. 3–5. Three sculptured casts. Only to one of these are attached some small remnants of the shell. The normal internal cast of Protodolium possesses smooth whorls. Such sculptured internal casts as occur at the locality 592 (see above, Lahillia!) may have been formed in the following manner: The shell was equally dissolved on the whole surface, so that finally the ornamentation was transferred to the cast when the innermost layers of the shell were dissolved. Locality.—Shag Point, loc. 592. Three specimens. Pleurotoma Lam. Pleurotoma otagoensis O. Wilck. 1922. Pleurotoma otagoensis O. Wilckens, Upper Cret. Gastrop. N.Z., N.Z. Geol. Surv. Pal. Bull. No. 9, p. 35, pl. 5, figs. 18, 19. The specimens are badly preserved sculptured casts, and exhibit nothing that can increase our knowledge of this species. Locality.—Shag Point, loc. 592. Six specimens.
