 Order Gymnophiona. (Gymnophiona Miiller.) 



Family: Cceciliidce Gray, 1850. 

 Order Urodela. 



Families: PleurodelidceGray, 1858; Salamandridoz Gray, 1858; Hynobiida Cope, 1866; 

 Desmognathidw Cope, 1866; Thoriida Cope, 1869; Plethodontidce Cope, 

 1866; Amblystamidce Cope, 1866; Menapomidce (Protonopsidce Gray, 

 1850), Amphiumida Cope, 1866; Cocytinida Cope. 

 Order Proteida. 



Family: Proteida Gray, 1850. 

 Order Trachystomata. 



Family: Sirenidce Gray, 1850. 



In 1885 Cope proposed 2 new orders, which he arranges with the other orders 

 already known, as follows: 



Order I. Rachitomi. Order V. Urodela. 



BATRACHIA. 



Order II. Embolomeri. Order VI. Trachystomata. 

 Order III. Stegocephali. Order VII. Anura. 

 Order IV. Proteida. 



The new order Rachitomi was to include forms like Eryops and the new order 

 Embolomeri was to include forms like Cricotus; the other orders were as they had 

 been given before. 



Zittel in 1888 proposed (642) the next classification of any note in his "Hand- 

 buch der Paleontologie," where it stands as follows: 



Classe AMPHIBIA. 



Ordnung i. Stegocephali. Ordnung 3. Urodela. 



Unterordnung i. Lepospondyli. Unterordnung i. Ichthyoidea. 



Familie i. Branchiosauridas Fritsch. Familie i. Phanerobranchia. 



2. Microsauria Dawson. 2. Cryptobnincliin. 



" 3. Aistopoda Miall. Unterordnung 2. Salamandrina. 



Unterordnung 2. Temnospondyli. Ordnung 4. Anura. 



Genera: Archegosaurus, Eryops, etc. Unterordnung i. Phaneroglossa. 



Unterordnung 3. Stereospondyli. Familie i. Ranidcc. 



Familie i. Gastrolepidoti. 2. Bufonida. 



2. Labyrinthodonta. 3- Cystignatliida Cope. 



Ordnung 2. Cceciliae. 4- Pelobatidce Boul.
