especially anteriorly, separated by three rows of scales. Supra- 

 oculars mostly small, but five or six larger are keeled and are 

 separated by a row of scales from supraorbitals. Twelve rows of 

 scales at widest part of front; three canthal scales, and six rows 

 of loral scales. Occipital not larger than surrounding scales, 

 smaller than auricular meatus. The extended hind leg reaches 

 to the middle of the orbit. Fan large, extending on thorax to 

 between shoulders. Digital expansions well developed, twenty- 

 five lamellae on penultimate joint of fourth posterior toe. 

 Postanal plates present in male.

The color is brown, changeable into bright green when the 

 skin is stretched. A wide blackish band extends from one orbit 

 to the other, passing over the nape posterior to the line of the 

 auricular meatus. A large triangular blackish spot above each 

 humerus meets its mate of the opposite side on the middle line, 

 and joins the postorbital band by its inferior anterior angle. 

 Upper lip pale, which color continues as a stripe to above ear. 

 Belly uniform green; tail below brown. 



This, the largest continental South American species, be-

 and a new species which I now describe as A. purpurescens* 



•ANOLIS PURPURESCENS Sp. BOV. 



Tail eylindric, covered with rather small flat equal keeled scales. 

 Dorsal and lateral scales sub-equal, small, convex, two medium rows at 

 one point a little larger and keeled obtusely. Ventral scales twice 

 as large as dorsals, smooth. Head 1.5 as long (to occiput) as wide, 

 without frontal ridges, and concave medially anterior to the orbits; 

 Frontal bone concave; parietal ridges converging posteriorly: Tibia 

 equaling length from end of muzzle to auricular meatus; the latter
