This concluding part of the Catalogue of the Fossil Eeptilia becomes 

 of the highest importance to students of Vertebrate Palaeontology 

 as affording, in a collected form, the results of those recent 

 researches which have been so successfully carried on, by Pro- 

 fessors Credner, Fraas, Fritsch, Gaudry, Seeley, and others, con- 

 cerning the structure and affinities of the Anomodontia and the 

 Amphibia. 



Splendid material for working out the anatomy of these oldest 

 and most generalized types of Eeptiles has of late years been obtained 

 from the Carboniferous and Permian formations of France, Germany, 

 Bohemia, South Africa, and also from Eussia, India, and North 

 America. 



The series of South-African Anomodont Eeptiles forms one of 

 the most important features in this section of the Museum ; indeed, 

 it may be justly claimed to be unrivalled ; many additions to the 

 Pariasauria having been made by Prof. Seeley while this Catalogue 

 was passing through the press. 



The finest Labyrinthodonts discovered are preserved in the 

 Museums of Leipsic, Stuttgart, and Prague ; but the series of speci- 

 mens of Archegosaurus from the Permian of Saarbrueken, and of
