SEELEY ON THE STRUCTURE, ORGANIZATION, American type is derived from Professor Copes writing and figures ; and althoughthe vertebral column obviously differs in many details, and especially in the greatdevelopment which the intercentrum attains, so as to occupy the visceral surfaces inthe dorsal region, there are many resemblances between Pareiasaurus and JEryops, sothat the relation between them may be closer than has been supposed, and, perhaps,justify the grouping of Eryops among true Reptiles, in the order Pareiasauria. Themode of attachment of the ribs appears to be similar. The external characters of theskull are not unlike. The shoulder girdle is almost identical in essential points. And Fig. 7. ilium ischium. Pelvis of JSryops megacephalus, after Cope, drawn in a position to compare with the os innominatum of Pareiasaurus and Anomodonts. if the pelvis is inclined so as to bring it into harmony with the Dicynodonts alreadyfigured, I can see no difference of plan to separate it from the pelvis of an AnomodontReptile. There has been no demonstration given of the Labyrinthodont organizationof JEryops or of the Amphibian organisation of its immediate allies, and, therefore,instead of interpreting resemblances to JEryops as Labyrinthodont characters, it seemsto me more legitimate to regard those characters as probably Pareiasaurian, especiallyas they are nearly all common to other Anomodonts. The Limbs of Pareiasaurus Baini. On the right side of the animals the limbs are well preserved, and were in theirnatural positions in contact with the pelvis and shoulder girdle, th
