2. Amphibians. — A species of Dasyceps, D. Bucklandi, occurs at Durham, 

 England, and others of Branchiosaarus, Hylonomus, Ophiderpeton, etc., in 

 European beds. 



3. Reptiles. — The Reptiles of the foreign Permian, like those of America, 

 are in part Rhynchocephalians. The earliest genus, Palceohatteria of Cred- 

 ner (1888) is from the Middle Permian (Rothliegende) of Saxony. A skull 

 from one of Credner's figures is shown in Fig. 1150. The palatine bone has

teeth, and also the vomer, as common in Amphibians. The close relations to 

 the New Zealand Hatteria are pointed out by Credner. The beak-like form 

 of the anterior part of the head, to which the name Rhynchocephalian refers, 

 is absent in this early species of the group. Proterosaurus (Fig. 1149) is a 

 related but more lizard-like form from the Upper Permian of Thuringia. 

 With the Palseohatteria occurs also (Credner, 1889) a related Reptile, the 

 Cadaliosaurus. Like Mesosaurus {Stereosternum) , these Permian Reptiles
