The family-group name hippopodiidae Cox, 1969 (Mollusca, Bivalvia) is a junior homonym of hippopodiidae Kolliker, 1853 (Cnidaria, Hydrozoa). Both names are currently in use and refer, respectively, to a monogeneric family of fossil bivalves from the Jurassic of northwestern Europe and the Triassic of East Africa, and a group of hydrozoans (Siphonophorae) of worldwide distribution. The senior homonym is much older and has been more widely used than the junior and it is proposed that the homonymy be removed by changing the spelling of the molluscan family group name to hippopodiumidae by emending the stem of the name of the type genus Hippopodium J. Sowerby, 1819, while leaving the hydrozoan name (based on Hippopodius Quoy & Gaimard, 1827) unchanged.

The purpose of this application is to conserve the name Hippotragus Sundevall, 1845 for the African roan, sable and blaauwbok antelopes, and a number of Pliocene and Pleistocene African and southern Asian fossil species. The name was suppressed in Direction 23 (1955) on the grounds that it had been overlooked in Opinion 109 (1929), in which Hippotragus Sundevall, 1846 was placed on the Official List. As a consequence the family-group name hippotraginae Sundevall, 1845 became unavailable. The names are usually cited as Hippotragus Sundevall, 1846 and hippotraginae Brooke in Wallace, 1876, although both names were published earlier in, and have been cited from, a further 1845 publication. The present application seeks to stabilise the nomenclature of hippotragine antelopes at the species, genus and family-group levels.
