the front of the orbit. Scales on exposed surfaces of femur and forearm 

 large, keeled. Fan large. 



The general color is a golden green. On the back is a series of blackish 

 chevrons, with the angle directed posteriorly, and with the lateral branches 

 thickened anteriorly. From the apex of each branch a delicate blackish 

 line descends vertically, stopping on the side below its middle, thus divid- 

 ing the side into vertical areas. Head more yellow above ; limbs reddish 

 brown.

This species is allied to the A. tropidonotus Pet. and the A. xmiformis 

 M., coming nearest the latter in its scutellation. The scales of the head 

 are however quite different, and the dorsal scales less numerous and of 

 a different form. The color is unlike anything hitherto observed in the 

 genus. 



One specimen from the San Juan river, Nicaragua, obtained by Robert 

 Kennicott. 



Anolis uniformis, sp. nov. 



This species is very near to the Anolis tropidonotus of Peters, and I 

 should hesitate to separate it had I not a considerable number of speci- 

 mens of both. The differences are three. First, the equality in size be- 

 tween all the scales of the frontal region, so that the supraorbitals can- 

 not be distinguished by size ; second, the smaller number of rows of 

 larger dorsal scales, and third, the uniformily smaller size. The color also 

 differs in all the specimens. 



The dorsal scales are in 10-12 rows, while in the A. tropidonotus they 

 are in 14-16 rows ; in both the scales are imbricate and not truncate. 

 There are three rows of supraoculars which are in contact with the supra- 

 orbitals as far as they go, the middle two only being larger than the rest. 

 There are five rows between the anterior prolongation of the supraorbitals 

 on the muzzle. All the scales have one strong keel ; those round the 

 small occipital consisting of little more than a longitudinal keel. Facial 

 rugse obsolete ; cavity slight. Auricular meatus much larger than occipi- 

 tal plate. The extended hind leg does not quite attain the nostril ; tibia 

 a little shorter than the short head. Seven rows of loreal scales ; and two 

 of suborbitals. Infralabials small, keeled. 



The color is reddish brown above and greenish below, limbs and head 

 above brown.
