The distinction between family-series and class-series nomina in zoological nomenclature, with emphasis on the nomina created by Batsch (1788, 1789) and on the higher nomenclature of turtles

The Code only regulates the scientific names or nomina of zoological taxa from the rank subspecies to the rank superfamily, but not those of taxa at ranks above the latter (class-series nomina), and it is shown here that its current Rules are somewhat ambiguous regarding the availability of family- Series nomina and the distinction between the latter and class- series nomina.
