THE HERPETOLOGY OF HISPANIOLA 237 



ocular, the posterior very large; nasal in contact with rostral; inter- 

 nasals not unusually elongate, separated from each other; the frontals, 

 prefrontals and internasals embracing a median series of three con- 

 tiguous scales, the central one slightly the largest, the anterior one 

 in contact with the rostral; frontals and prefrontals separated from 

 the canthals by an elongate scale; three superciliaries ; six supraoculars; 

 occipital small, bordered by two distinct pairs of parietals on each 

 side, the inner about two-thirds as large as the outer; four (on left 

 side of head only three) upper labials and five lower labials to a 

 point below the center of the eye; a conspicuously enlarged, heavily 

 keeled scale on the temporal region just above and in front of the ear 

 opening; anterior border of the ear with four large projecting scales. 

 Dorsal scales large, imbricate but not mucronate except towards the 

 tail, some of the dorsals near the median line being hexagonal in 

 shape with the tips squarely cut off; laterals slightly smaller than 

 dorsals; ventrals larger than dorsals, smooth, their posterior edges 

 highly denticulate; about 46 scales around the middle of the body; 

 about 57 scales from occiput to a point directly above the vent; 

 about 14 dorsal scales to a head-length; nuchal scales quite small; 

 those on the side of the neck like the dorsals; those behind the ear 

 keeled and imbricate, not granular. Shoulder folds present, but no 

 lateral folds. The adpressed hindleg reaches to about the center of 

 the eye. Digits compressed; the fourth toe with 26 keeled lamellae. 

 A low but distinct dorsal crest and a higher caudal crest; the other 

 caudal scales mucronate. The keels of the lateral and dorsal scales 

 are directed backwards and upwards, so that the longitudinal scale- 

 rows converge strongly on the back. Tail highly compressed. 



"Dimensions. — Snout to vent, 65 mm.; head, 14 mm.; tail (tip 

 reproduced), 87 mm. 



"Color (in alcohol). — Head brown; back iridescent bronze-green 

 with indications of cross-bands on the nuchal region ; traces of a dark- 

 brown, much interrupted lateral stripe leaving the eye, continuing 

 over the shoulder and onto the side of the tail where it persists only 

 as a series of small brown spots widely separated; upper surfaces of 

 arms and legs bronze. Chin and throat with alternating dark brown 

 and light bronze stripes which are somewhat irregular and tend to 

 anastomose. Remainder of under surface tan, with occasional 

 bluish scales. Beneath the eye two light patches, set off by dark 

 vertical marks. 



" Variations. — In the two paratypes, secured under the same con- 

 ditions as the type specimen, not much variation is shown. The 

 scales around the body seem to be 45 to 49 in number in these two 

 paratypes, but as the longitundinal rows are exceedingly uneven, due 

 to the convergence on the back, the count varies at practically every 

 scale. The number of scales from the occiput to a point directly
