THE HERPETOLOGY OF HISPANIOLA 135 



of enlarged, keeled scales, the inner ones about as large as the ventrals, 

 the outer rows becoming smaller and merging rapidly with the lateral 

 granules, which in their turn give way to the medium-sized, keeled, 

 and imbricate ventrals; about 17 or 18 scales along the middle of the 

 back equal the standard distance from tip of snout to center of eye; 

 scales of gular fan scarcely longer than ventrals and only half as wide, 

 wrinkled and set in longitudinal series on the naked skin of the gular 

 fan, the edge of which is slightly thickened; throat scales quite small, 

 mostly rectangular, bluntly keeled; arms above covered with keeled 

 scales as large as the ventrals; femur with some scales considerably 

 larger than the ventrals ; scales covering hands and feet very strongly 

 pluricarinate ; digits very long and slender, expansion moderate; 20 

 lamellae under the second and third phalanges of fourth toe, 33 under 

 the entire toe; tail very long, more than 2% times the length of the 

 head and body, moderately compressed, covered by large, imbricate, 

 keeled scales with but slight indications of verticils, and the median 

 series above consisting of similar but somewhat more heavily keeled 

 scales forming a very feebly serrated edge; a pair of postanal plates 

 large and prominent. Nuchal fold quite apparent, dorsal fold very 

 weak. 



Dimensions: Head and body, 38 mm.; tail, 105 mm.; tip of snout 

 to posterior ear, 12 mm.; width of head, 6 mm.; foreleg, 13 mm.; 

 hindleg, 30 mm. 



Color (in alcohol) : Above olive-brown, with a distinct metallic 

 iridescence; below olive-buff, also highly iridescent; a white stripe 

 originating on the rostral, continuing backward along the upper lip, 

 involving the lower half of the ear, and continuing sharply demarked 

 along the sides nearly to the groin, where it gradually fades out; 

 below this lateral stripe between axilla and groin a few dusky mot- 

 tlings of light olive-brown set it off much less sharply from the ventral 

 color; skin of gular fan white, the scales besetting it finely punctate 

 with minute black dots; lower labials and adjoining scales powdered 

 with many small black dots mostly concentrated on the anterior 

 portions of the scales ; upper portions of limbs with similar powderings 

 of dots, which on the hindlegs form themselves into broad indistinct 

 dark bars and which appear on the tail even less distinctly; a very 

 distinct dark-brown diagonal bar across the temporal region. 



Variations. — In 162 individuals, all from Rio San Juan, the supra- 

 orbital semicircles were in contact in only 3 cases; there was one 

 row of scales between the semicircles in 77 cases; two scale rows in 

 80 cases, and 3 scale rows in 2 cases. 



The maximum size of this species is apparently attained by a male, 

 U.S.N.M. No. 74829, of which the head and body taken together 

 measure 40 mm. and the tail 116 mm.
