Case 3384: Cornwallius tabatai Tokunaga, 1939 (currently Paleoparadoxia tabatai; Mammalia, Desmostylia): proposed conservation of usage of the specific name by the designation of a neotype.
Bull. Zool. Nomenclature 64(2): 113-117. June 2007.
–In its Opinion 2232, the ICZN (2009) declined to take action on this proposal, on the grounds that Inuzuka's (2005) designation of a lectotype, which threatened the established usage, was invalid to start with. Consequently, Shikama's (1966) original designation of the Izumi skeleton as neotype of P. tabatai was maintained, as Hasegawa & Kohno desired.
