Opinion 1535: Halianassa studeri von Meyer, 1838 (Mammalia, Sirenia): neotype designated; and Halitherium Kaup, 1838 (Mammalia, Sirenia): Pugmeodon schinzii Kaup, 1838 designated as the type species.
Bull. Zool. Nomencl. 46(1): 83-84. Mar. 1989.
–Pursuant to the petitions of Domning (1987b), Halitherium is deemed to be the correct original spelling of Halytherium; the holotype of Pugmeodon schinzii is designated as the neotype of Halianassa studeri; P. schinzii is designated as the type species of Halitherium; Halitherium and (Pugmeodon) schinzii are placed on the Official Lists of Names in Zoology; and Halianassa, Halytherium, and (Halianassa) studeri are placed on the Official Indexes of Rejected and Invalid Names. The main outcome of these actions is that the name Halianassa studeri is fixed as an objective junior synonym of the Oligocene species Halitherium schinzii, and Halianassa and H. studeri are thereby made unavailable for application to the Miocene specimens for which they have most often been used.

Opinion 2232 (Case 3384): Cornwallius tabatai Tokunaga, 1939 (currently Paleoparadoxia tabatai; Mammalia, Desmostylia): proposed designation of a neotype not accepted.
Bull. Zool. Nomencl. 66(3): 295-296. Sept. 2009.
–The neotype fixation proposed by Hasegawa & Kohno (2007) is hereby declined and no action by the Commission is taken, on the grounds that the lectotype designation by Inuzuka (2005), which the proposal sought to set aside, was invalid to begin with. Accordingly, Shikama's (1966) designation of the Izumi skeleton as neotype of P. tabatai is maintained, as Hasegawa & Kohno desired.
