THE HERPETOLOGY OF HISPANIOLA 165 



May 11, 1931. Top of head with two ( )-shapGd frontal ridges, 

 disappearing before reacliing the level of the nostrils and enclosing 

 a frontal hollow; head scales nearly smooth, only those of the supra- 

 orbital disks with a keel; the distance between the anterior portions 

 of the orbits very nearly equaling that from the orbit to the end of 

 the snout; rostral low, slightly narrower than the mentals; five or 

 six scales between the narrow scales bordering each nostril above; 

 supraorbital semicircles composed of six enlarged scales, the second 

 much the largest, the thu'd and fourth in close contact with their 

 fellows for nearly their entire length; occipital about three-fourths 

 the size of the ear opening, separated from the supraorbital semicircle 

 by one row of scales; a single scale of the anterior margin of the 

 occipital plate a little larger than the surrounding scales; the scales 

 posterior to the occipital irregular; supraorbital disk composed of 

 about seven polygonal keeled scales, separated from the semicircle 

 by one or two rows of relatively large granules, which in front of the 

 disk enlarge to form a patch of small but distinct scales; canthus 

 rostralis sharp, consisting of four elongate shields of which the middle 

 two are the longer; superciliary ridge consisting of one very elongate 

 scale followed by a short one, this in turn being followed by a double 

 row of differentiated scales larger than the granules above and below 

 them; loreal rows five; subocular semicircle keeled, not in contact 

 with the supralabials; supralabials eight or nine, the suture between 

 the seventh and eighth under the center of the eye, the ninth very 

 small indeed; temporal granules shghtly smaller than the dorso- 

 laterals; a well-marked double series of small scales forming the 

 supratemporal line; dorsal and lateral granules relatively much larger 

 than in Anolis cybotes cybotes, flattened, not tubercular; a median 

 enlarged series of keeled scales down the center of the back beginning 

 just behind the occipital scale, not diminishing on the sacrum and 

 continumg on the tail as a low, serrate ridge; ventral scales relatively 

 very much smaller than those of Anolis cybotes cybotes, imbricate, 

 rounded beliind, smooth, those on the throat small and bluntly 

 tuberculate; anterior face of forelegs and hindlegs covered with large 

 faintly keeled scales, those on the anterior femur considerably larger 

 than the largest ventrals; scales covering hands and feet above faintly 

 unicarinate or practically smooth; digital expansion wide, with about 

 16 lamellae imder the second and third phalanges of the fourth toe, 

 26 under the entire toe; tail short, compressed, with well-marked 

 verticils of shghtly enlarged rectangular scales, those between being 

 romided and smaller, in about seven vertical, somewhat irregular 

 series, slightly imbricate, heavily keeled, surmounted by a strongly 

 serrate edge of enlarged triangular scales, three to every verticO, the 

 last one the largest; dewlap naked, with many close-set series
