The Miiuvsaiiria are characterised by somewhat narrow crania, smooth cranial 

 simple or non-plicated teeth, well-developed liml) bones and ribs, elonjjjated

Though ])robably to be included in the group Stci/ncepJaih, as defined, and 

 l»redoniiiiantly llatrachian in their atiinities, they presented in form, clothing, and 

 probably in habits of life, a closi' approximation to the lacertiatis. Their predomi- 

 nating terrestrial habits ale evidenced bv the circumstance that in nearly all the 



s[)ecies the length of the t 



(iinir coincides very nearly with that of the mandible, while 

 their lacertian ibrni is indicatid ly the liict that in death their crania and skeletons 

 lie on one side and not on the hack or front. 



The following genera of this grouji are represented in the erect trees of the South
