The purpose of this application, under Articles 23.9.3 and 81.2.1 of the Code, is to conserve the specific name 'Productus compressus' Waagen, 1884 for the type species of the Permian brachiopod genus 'Compressoproductus' Sarytcheva in Sarytcheva et al., 1960. The name is a junior primary homonym of 'Productus compressus' Say in James, 1823, which has been seldom used since it was established. Waterhouse & Piyasin (1970) proposed 'Compressoproductus morahpressus' as a substitute name for Productus compressus Waagen, 1884, but this name has never been used other than by Waterhouse (1978, 1983). It is proposed that the name 'Productus compressus' Waagen, 1884 be conserved by suppression of 'Productus compressus' Say, 1823.
