SYSTEMATIC ACCOUNT OF THE SPECIES. 
Keys. 
The following series of keys has been prepared to facilitate identifications, 
but they cannot be expected to prove serviceable invariably. The young of 
many species differ greatly from the adults, and, moreover, the adults often 
vary inter se in a surprising degree. With Anolis especially the difficulty of 
exact diagnosis is very great. The keys therefore should be used in connec- 
tion with the detailed descriptions; or, when possible, comparatively with 
typical or authentically named specimens.
