DESCRIPTIONS OF NEW AND LITTLE-KNOWN FOSSIL 

 LIZARDS FROM NORTH AMERICA 



By Charles W. Gilmore 



Since the appearance of my memoir entitled "Fossil Lizards of 

 North America" ^ in 1928, the United States National Museum has 

 acquired, either through purchase or from its various paleontological 

 expeditions, a number of fossil lizard specimens. Some of these con- 

 tribute to a better understanding of forms already known, while 

 others are here described as new. The type of Rhineura Htembergii 

 Walker is illustrated for the first time. AJl the illustrations have 

 been made by Sydney Prentice. 



Family AMPHISBAENIDAE 



Genus RHINEURA Cope 



The genus Rhineura as applied to extinct forms now includes the 

 three species R. liatcherii Baur, R. coloradoensis Cope, and R. stern- 

 hergii Walker. A fourth species, R. minutus, is described below. 

 All are from the Oligocene, R. coloradoensis being from the Chadron, 

 the others from the Brule.
