Though the fos.sil turtles of the Mauvaises Torres of Nebraska, liave most analogy, in tlie details of 

 the anatomy of the carapace, to the land tortoises, still their general form and appearance clo.sely 

 approximate to the arpiatic turtles, and for this reason it is not improbable that they were partly 

 aquatic in their habits.
