DESCRIPTION OF A NEW SUBSPECIES OF CNEMI- 

 DOPHORUS LBMNISCATUS LAURENTI. 



By AeKxander G. Ruthven. 



A study of a large series of specimens from Colombia and 

 British Guiana reveals the fact that the Colombian specimens 

 usually referred to Cnemidophorus lemniscatus differ from 

 specimens from British Guiana sufficiently to merit subspecific 

 recognition. The material studied consists of the collections 

 of the Bryant Walker Expeditions to British Guiana and the 

 Santa Marta Mountains, and nine specimens from the Santa 

 Marta Mountains in the jMuseum of Comparative Zoology, 

 Cambridge, Massachusetts. 



Cnemidophorus lemniscatus gaigei,^ subsp. nov. 

 Diagnosis: Similar to Cnemidophorus lemniscatus but 

 dififering in the following particulars: size larger; the width 



1 Named for Frederick M. Gaige, entomologist of the expedition to Colombia.
