164: Ruthven — Description of a New Anolis from Brazil. 



broad, longer than the tibia by about half the distance between the eye 

 and ear. Upper head scales, except enlarged supraoculars, smooth, 9 

 and 10 enlarged and feebly keeled supraoculars. Scales of supraorbital 

 semicircles enlarged, the semicircles in contact medially. Occipital scale 

 large, as large as the ear, much larger than adjacent scales, and separated 

 from the supraorbital semicircles by a row of large plates. Canthal scales 

 2; loreal scales in five rows, 8 upper labials and 7 and 8 lower labials; 2 

 mental scutes. Ear opening a rather small and nearly vertical oval. 

 Body a little compressed, no dorsal crest. Gular appendage moderately 

 large, scales smooth. Dorsal scales keeled, very small, becoming slightly 

 larger on the median line and grading into the minute laterals. Ventral 

 scales smooth, much larger than the dorsals. Digital expansions broad. 

 Tail rather strongly compressed, and with a sharp ridge, for the proximal 

 two-thirds of its length, distal third rounded. Sides of flattened portion 

 with small obtusely keeled scales between single circumcaudal rings of 

 larger, elongate, obtusely keeled scales; a row of enlarged keeled scales 

 along the top of the crest and several rows on the ventral surface. Pos- 

 teriorly the lateral caudal scales become larger and more sharply keeled 

 and grade into the long, narrow, sharply keeled, and strongly imbricated 

 scales that cover the rounded part. No decidedly enlarged postanal 

 scales. The color can not be made out satisfactorily. The dorsal sur- 

 faces seem to have been yellowish ash, indistinctly marked with dark 

 brown. The darker markings were evidently distinct only on the neck, 

 temporal region and tail; they form a few elongated streaks on the neck, 

 a poorly defined broad stripe from the eye to above the ear, and small 

 spots on the top of the caudal ridge. Lower surfaces yellowish.
