“ AMPHIBIA, a zoological term originally employed by Linnaeus to denote a class of the Animal Kingdom comprising crocodiles, lizards and salamanders, snakes and Caeciliae, tortoises and turtles and frogs ”

“ An appeal made by Müller for observations on the development of the Caeciliae, and of those Amphibia which retain gills or gill-clefts throughout life, has unfortunately yielded no fruits.
In 1825 P. A. Latreille [6] published a new classification of the Vertebrata, which are primarily divided into Haematherma, containing the three classes of Mammifera, Monotremata and Aves; and Haemacryma, also containing three classes—Reptilia, Amphibia and Pisces. ”

“ Sir Richard Owen, in his work on The Anatomy of Vertebrates, followed Latreille in dividing the Vertebrata into Haematotherma and Haematocrya, and adopted Leuckart’s term of Dipnoa for the Amphibia. T. H. Huxley, in the ninth edition of this Encyclopaedia, treated of Brongniart’s Batrachia, under the designation Amphibia, but this use of the word has not been generally accepted. (See Batrachia.) (T. H. H.; P. C. M.)
↑ Brongniart’s Essai d'une classification naturelle des reptiles was not published in full till 1803. ”
