phrydidcB, Discoglossidce.

 Order Gymnophiona. (Gymnophiona Miiller.) 



Family: Cccciliidcz Gray, 1850. 

 Order Urodela. 



Families: Plcurodelida Gray, 1858; Salamandrida: Gray, 1858; Hyiwhiidts Cope, 1866; 

 Desmognathida Cope, 1866; Thoriidas Cope, 1869; Plethodontidce Cope, 

 1866; AmblystomidcE Cope, 1866; Menopoinida; (Protonopsida Gray, 

 1850), AuiphiitmidfE Cope, 1866; Cocytinidce Cope. 

 Order Proteida. 



Family: Proteida Gray, 1850. 

 Order Trachystomata. 



Family: Sire-nidce 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. 



Order II. Embolomeri. Order VI. Trachystomata. 



BATRACHIA. 



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:
