THE Sauropoda are now generall.y recognized by anatomists as a well-marked order of the Sub-class ])inosau1"1a. In the previous articles of this series, the main characters of the two families of this order (AtlantosauridCl3 and M01'Osaui"'idce) alread.y named by the writer have been given.* A third family is represented by the genus Diplodocus, a study of which, more especially of the skull. throws light on the whole group of Dinosaurian reptiles.
