HISTORICAL REVIEW 



Certain lizards of the genus Cnenudoplionis have been known to 

 naturalists since the early part of the eighteenth century. Perhaps 

 tlie fii-st to be carried from the New World were lenuihcatus and 

 munnus. These interesting forms were figured by Seba in his his- 

 toric work of 1734 and 1735. The first appeared as Lacerta leninis- 

 cata. in the tentli edition of the Systemae Naturae, but the second was 

 overlooked until 17G8 when it was named by Laurenti. Only one 

 other species of Gnemidoflionts was made known by Linnaeus, 

 namely, the Lacerta sexlineata of 1766. During the period between 

 1766 and 1839 the generic position of the two Linnaean species of 

 Gnemidophorus was much varied. Ahhough often referred to the 

 hirge and uuAvieldly genus LMcerta, these early forms were also 

 placed at times in the Sefs of Laurenti, the Ameiva of Meyer, and
