  • 🧍 The Lists Editor has corrected the original spelling of the specific epithet aegyptiaca to aegyptia. However, the Latin adjective aegyptiacus -a -um has been used by Aulus Gellius (a grammarian of the second century A.D.) and, later, by Saint Jerome. Examples (i) Aulus Gellius: Noctes Atticae, Liber X, paragraph 10: Causam esse huius rei Apion in libris aegyptiacis hanc dicit, ... (ii) Saint Jerome: Latin Vulgate, Genesis 41, 45 ... et vocavit eum lingua aegyptiaca ... — 🧍 The Subcommittee on the taxonomy of Halobacteriaceae recommends the use of the name Natrialba aegyptiaca.
