HERPETOLOGY OF PORTO RICO. 639 



many times larger than the largest dorsal granules; supraorbital disk 

 consisting of about ten enlarged, polygonal keeled scales surrounded 

 by several rows of granules; two small and one large scale between 

 the superciliaries and the supraocular semicircle bordering the supra- 

 ocular granules anteriorly; canthus rostralis sharp, consisting of five 

 elongated shields, the second one from the superciliary ridge being 

 particularly large; superciliary ridge consists of one very long and 

 narrow anterior shield followed by a double series of smaller scales 

 which separates the supraocular granules above from those covering the 

 lateral orbital region; loreal rows six, with raised lower edges; subocu- 

 lar semicircle keeled, separated f rom supralabials by one row of scales; 

 supralabials nine, the suture between seventh and eighth being under 

 the center of the eye; temporals granular, with a bare indication of an 

 enlarged supratemporal line; dorsals minutely granular, the granules 

 being pointed or keeled, with a bare indication of a median double 

 series of slightly larger ones; ventral scales large, imbricate, rounded 

 behind and flat or slightly convex, those on the throat smaller, more 

 elongate and more strongly convex; fore legs above with sharply 

 keeled scales, those on the upper arm smaller, those on the lower arm 

 larger than the ventrals; anterior face of femur and underside of 

 tibia similarly covered, the scales on the former gradually decreasing 

 on the underside, the upper side of both being covered with granules 

 like those on the back; scales on fingers and toes sharply carinate; 

 digital expansion wide, about 20 lamella? under phalanges ii and iii of 

 fourth toe; tail moderate, compressed, the basal half above with a fin 

 supported by about 14 bony rays; caudal verticels distinctly indicated 

 by a vertical series of more enlarged scales, those between being 

 pointed and smaller, in about nine vertical, somewhat irregular 

 series, all imbricate and keeled; the scales covering the upper edge of 

 the tail raised and spinous, forming a serrated ridge the teeth of which 

 increase in length toward the posterior end of each verticel, about six 

 spines corresponding to each verticel in the basal portion; dewlap 

 large, with distant series of scales, the anterior edge thickened; post- 

 anal scales slightly developed. 



The dermal folds on upper neck and back are present, the former 

 quite prominent, the latter perhaps less so than in Anolis gundlachi.
