12 NEW REPTILES AND STEGOCEPHALIANS FROM 



THE LITERATURE OF THE TRIASSIC VERTEBRATES OF 



NORTH AMERICA. 



Our knowledge of the Triassic vertebrate life of North America is so limited 

 that it is not yet time to attempt a summary statement of the material at hand, 

 but it will not be amiss, as a step in progress, to list the main articles which have 

 from time to time partially reviewed the work done up to the time of their appear- 

 ance. The bibliographies in these articles will lead to the original publications.
