difference of opinion as to which name has the priority and ought to 

 be used. If the question is to be decided by strict priority then 

 neither name must be used, but Owen's term Serratidentia, proposed 

 in 1876 for the group to which Pareiasaurus belongs. As, however 

 Owen believed Pareiasaurus to be a Dinosaur, and as no one has 

 ever adopted Owen's term for the reptiles with a roofed temporal 

 region it seems necessary to use one of the other two terms. As 

 Seeley in 1888 manifestly did not mean his Pareiasauria to include 

 any but Pareiasaurus -[ike animals and in his classification puts the 

 Procolophonia and the Cotylosauria as other orders of equal value we 

 can hardly use his term as a super-order. On the other hand, Cope 

 in 1889 clearly made Cotylosauria an embracing order including all 

 the primitive reptiles with roofed temporal regions. And as most 

 later writers have continued to use Cope's term in this sense it 

 seems best to use the term Cotylosauria as a super-order and to use 

 the term Pareiasauria as a suborder of the Cotylosauria. 



In the following list I have used the terms which seem to me those 

 that have most claim. Very doubtful species I have omitted. 

 Species that are a little doubtful but possibly good I have re- 

 tained :
