266 CLASSIFICATIONS OF THE AMPHIBIA. 



nopsis Reptilium,' — a work which then contained more ac- 

 curate and further information of these animals, than any 

 other that had appeared, and is still accounted one of author- 

 ity and reference, — divided his seven genera into two orders, 

 viz., those reptiles which leap in their progressive motion, 

 and those which walk ; as follow.— 



Classis.— REPTILIUM. 



Ordo I. — Salientia. Genera. — Pipa. Bufo. Rana. Hyla. 



Ordo II. — Gradientia. Genera. — Proteus. Triton. Salamandra. 



The Count de La Cepede, in the i Hist. Nat. des Quad. 

 Ovip.' tome i., which was given to science in 1788, naming 

 them Oviparous Quadrupeds, classed his four genera just as 

 simply, by taking for his characters the presence and absence 

 of a tail ; thus. — 



Classis I. — Quadrapedes ovipari caudati. 



Gen. II. Lacertus. Div. 8. Salamandra. 



Classis II. — Quadrapedes ovipari ecaudati. 



Genera. — Rana. Hyla. Bufo. 



Dumeril, (Zoologie Analytique, 1806), as Daudin had be- 

 fore done in his beautiful work, — c Hist. Nat. des Reptiles,' 

 1802, — followed Brongniart, (see his Essai dans le ' Bulletin 

 de la Societe Philomatique,' No. 36), who in 1799 first di- 

 vided the class Reptilia into four orders, and in the last of 

 which he placed these animals. Dumeril distinguished them, 

 after La Cepede, by the want and presence of a tail, and 

 merely assigned them new Greek, instead of the old Latin, 

 titles. His genera are the same as Laurenti's, with the addi- 

 tion of Siren ; as are here seen. 



Classe III.— REPTILES. 



Ordre4. Batraciens. 



Ire Famille. Anoures. Sans queue. 



Genres. — Pipa. Crapaud. Grenouille. Rainette.

The same system is adopted again, but with a new family, 

 by Oppel in his * Reptilien,' 1811 ; as follows. 



Classis III.— REPTILIA. 



Ordo III. Nuda, (Klein). Ordo IV. Batracii, (Brongniart).
