head, the moderately-long neck, the presence of a broad and generally brilliantly- 

 colored appendage on the throat of the males, the slender body, which may be 

 either compressed, cylindrical, or slightly depressed, the relatively -long hind-limbs, 

 the large feet, in which the toes are of very unequal length, and their middle 

 joints expanded, with smooth transverse plates on the under surface, and the long, 

 curved, and sharp claws, which are raised above the level of the expanded joints. 

 The tail is long and hard, although not prehensile; the covering of very* minute 

 scales on the back and tail is not unfrequently elevated to form a crest; the cheek 

 teeth are characterized by their distinctly tricuspid crowns; and teeth are generally 

 present on the pterygoid bones of the palate. Lastly, these lizards possess the 

 power of changing their color to even a greater extent than is the case with the

chamseleons. From among more than one hundred species belonging to the genus 

 we select for illustration the red-throated anolis (Anolis carolinensis] , which inhabits 

 the Southeastern United States and Cuba, and presents the following distinctive 

 features. The head, which is long, triangular, and depressed, is nearly smooth in 

 the young, but in the adult has well-marked frontal ridges, and some large rough 

 shields on the crown; and the appendage on the throat of the males is relatively 

 small. The body is not compressed, flat beneath, and not keeled above; the scales 

 on its upper and lower surfaces being keeled and approaching an hexagonal form, 

 with their edges either in apposition or slightly overlapping. The tail is cylin- 

 drical and tapering, with some slightly-enlarged scales on its upper surface, and
