stating that, "the scales (of Sceloporus elongatus) are not so strongly 

 carinated, the keel being lower and mostly confined to the terminal 

 half of the scale." Since similar variations were found among speci- 

 mens of the swifts collected in eastern Colorado, all of our Colorado 

 specimens are here listed as Sceloporus consohrinus. 



Several of the specimens of this swift in the museum of the Uni- 

 versity of Colorado have small red mites clinging to various parts of the 

 body, particularly to the sides of the head in the lateral folds.
