From Ancient Greek λισσός (lissós, “smooth”) + ἀμφίβια (amphíbia), nominative neuter plural of ἀμφίβιος (amphíbios, “two types of life”), from ἀμφί (amphí, “of both kinds”) + βίος (bíos, “life”).
Lissamphibia has previously been used to include all extant amphibians, while excluding the main Paleozoic tetrapod groups. There is debate as to whether it constitutes a clade. Some writers argue that Gerobatrachus hottoni (early Permian) belongs in Lissamphibia. For more details, see Lissamphibia on Wikipedia.Wikipedia
