lower sides, in contact behind with anterior nuchals, the lower much 

 wider behind, wedge-shaped, with the apex towards the front and 

 narrowly in contact with the anterior temporal ; two small scales be-

 teriorly with three small lobules; mental medium, followed by two 

 unpaired postmentals, the anterior narrow, band-like, with parallel 

 anterior and posterior edges, the posterior larger, pentagonal, mucii 

 wider than long; seven lower labials, sixth long and narrow; 24 

 perfectly smooth subequal scales around the middle of the body, 48 

 in a longitudinal series next to the median line of the back between 

 nuchals and a line from groin to groin ; a pair of large preanal plates; 

 length of hind leg contained about twice and a half in distance from 

 snout to vent ; the adpressed limbs overlap by about the length of the 

 fingers; scales on dorsal aspect of femur small, becoming abruptly 

 much larger on underside, the largest being more than three times as 

 large ; sole of hind foot with subequal, small, nearly granular scales 

 and a few larger ones near the heel; 14 scales under the fourth toe; 

 a small scale behind each corner of the vent with a faint indica- 

 tion of a pointed keel or tubercle; tail gradually tapering, with a 

 series of median, wide, transverse plates on the underside. 



Color (in alcohol) : above dark, nearly blackish brown, becoming 

 paler brownish gray on terminal* half of tail, with five longitudinal 

 narrow yellowish stripes, one on the dorsal median line, the next on 

 the middle of the third scale row from the median line, and a lat- 

 eral one on the fifth and slightly also on the sixth scale row from 

 the median line; the median stripe bifurcates on the interparietal 

 shield proceeding forward over the frontoparietals and the lateral 

 margins of the frontal, across the middle of the prefrontals meet- 

 ing again on the rostral which is pale ; the next stripe proceeds for- 

 ward on the head over the outer edge of the supraoculars; the lat- 

 eral stripe extends forward through the ear-opening and the lower 

 half of the temples to the supralabials ; the median stripe disap- 

 pears on the terminal half of the tail, the next one on the basal third, 

 and the lateral one just above and behind the insertion of the hind 

 leg; underside from pectoral region forward and from groin back-
