294 ON TWO NEAV SPECIES OF LABYRINTHODONTS. 



and this, with the evidence previously recorded, serves to show that 

 the Anomodonts and Lab3Tinthodonts of the Permian of Texas, of 

 the probablj' equivalent beds of Brazil, and of the Karoo system of 

 the Cape were closely related, not only to one another, but also to 

 those of the Gondwanas of Central India and the Hawkesbury beds 

 of Australia ; while more or less closely allied types also occur in 

 the Upper Permian of the Urals. 



[Since the foregoing was written I have been informed by Dr. E. 

 Fraas that the Munich Museum possesses some rhachitomous 

 Labyrinthodont vertebrae from the Karoo system, which are pro- 

 bably referable either to the form described above or to Ehytid- 



osteus.^
