Each entry of this nomenclator links to the protologue (Gk. protos, first, logos, discourse) which includes everything associated with that name when it was first published. Information from these data are used in the determination of the nomenclatural type for that name, being that element (usually a preserved specimen) to which that name is permanently attached.
