The examination of the above specimens shows that Proajlophon 

 has its affinities with PaUeohatteria, and that it is not a near ally 

 of the Theriodonts. In only one important character does it re- 

 semble the Theriodonts viz. the possession of an ossified precora- 

 coid ; while the possession of abdominal ribs, a persistent noto- 

 chord, and the presence of 3, 4, 5, and 4 phalanges in the 4 outer 

 digits, remove it far from the Dir.ynodonts, tl\e Theriodonts, and 

 the Monotremes and place it somewiiere among the primiti\'e 

 Rhynchocephalians,— posf^ibiy not far from PaJceohatteria.
