with the loreal; three posterior supraoculars separated from the 

 supraciharies by a single row of granules; last supraocular separated 

 from the outer occipitals by a double row of small scales; five large 

 supralabials ; five large infralabials; between infralabials and chin- 

 shields a wedge of three or four small scales extending only to the 

 third infralabial; chin and throat covered with granules of slightly 

 varying size, no distinct grouping of the larger granules; on the area 

 between the two throat folds several rows of large hexagonal scales; 

 under side of the body with eight longitudinal rows of scales (ten 

 including the large granules terminal on each cross row) and thirty- 

 five transverse rows; preanal plates, a pair of large marginal ones and 

 a median pair of about the same size; on the lower arm a single, 

 partly double row of antebrachials breaking up into granules just 

 before reaching the elbow joint; on the upper arm a single row of 

 much narrower brachials; on the posterior side near the elbow joint 

 a double row of postbrachials scarcely differentiated from the granules 

 of the arm; under side of the thigh covered with three rows (four 

 proximally) of hexagonal plates of which the outer series is larger than 

 the others; twelve femoral pores; on the under side of the tibia two 

 rows of plates, the outer row greatly enlarged; upper side of the 

 wrist with an irregular, part regular, series of transverse plates; outer 

 toe extending a little further than the inner; tail covered with smooth, 

 oblique scales; about thirty scales in the fifteenth ring from the base. 



Coloration: — General tonality milky, slightly olive on the head, 

 grayer on the tail; three dark brown or blackish bands running the 

 length of the body but not extending on the tail; the median dark 

 band arises in the occipital region and extends not so far as the thigh ; 

 the two lateral dark bands arise just before the eye and extend back- 

 ward covering nearly all the flanks; ventral surface including the lower 

 part of the flanks whitish tinged with blue; under surface of the tail, 

 and the gulars tinged with greenish. 



Variation: — The female and young differ from the adult males 

 in being generally brighter, that is in being more black and white. 



Remarks: — The description was made of an adult male that meas- 

 ured sixty-six millimeters from snout to vent. 



Habitat: — Confined to Great Inagua in the southern Bahamas.
