Description.— No. 5706rt, U.S.N.M. Adult ; Oahu or Kauai ; collection 

 U. S. Exploriug Expeditiou. Eostral broadly in contact with nasals 

 and frontonasal; nasal long, lozenge-sbaped, pierced in the middle by 

 the round nostril and with a groove, or suture, near the upper posterior 

 corner from nostril to loreal suture; frontonasal large in contact with 

 nasals, first loreals and prefrontals, not in contact with frontal; frontal 

 small, considerably smaller than frontoparietal, in contact with two 

 supraoculars; four supraoculars, second, third, and fourth in contact 

 with frontoparietal; four supraciliaries (or five on the right side of the 

 present specimen); frontoparietal large, nearly rectangular, narrowly 

 in touch with frontal, and composed of the fusion of the two fronto- 

 parietals and interparietal; parietals large, broadly in contact behind 

 frontoparietal; one pair of large nuchals scarcely in touch behind parie- 

 tals, and followed by a double series of short very wide plates or scales 

 which gradually decrease in width backward, emerging into the two 

 median dorsal scale rows; first loreal high and narrow separating nasal 

 from prefrontal; secotul loreal which is C(msiderably lower and wider 

 in contact behind, with only the upper preocular which is considerably 

 larger than the lower one; the upper suture of the supralabials from 

 the rostral to the anterior side of the subocular supralabial deeply 

 depressed, forming a slightly arclied groove which even indents the 

 anterior portion of the subocular supralabial; seven supralabials, sixth 

 largest, fifth forming a long low subocular (eight on left side, sixth 

 entering orbit, in present specimen); ear opening round, nearly the size 

 of the anterior supralabials, with smooth margins without anterior 

 knobs or lobules; mental rather short, followed by a single unpaired 

 postmental; six narrow infralabials, fourth and fifth very elongate- 

 twenty-eight rows of scales, more or less longitudinally rugose, those 

 on back larger, nearly twice the size of those on sides and belly, their 

 rugosities forming about five very blunt keels; those bordering anal 

 opening in front scarcely enlarged; a median series of moderately 

 widened scales under tail; covering under toes consisting of smooth 

 scales like those on top. 



Ground color above a light brownish bronze with numerous irregular 

 dark brownish dots all over and a distinct pale band on each side from 

 superciliaries to base of tail, and even fairly indicated on basal half 

 of the latter; this pale band has very ragged edges, being intruded 

 upon by blackish spots which form an irregular dark border on each 

 side; sutures on the head with dark edges; sides and upper side of 

 legs darker brownish with numerous whitish dots scattered all over; 

 underside whitish; terminal third of tail becoming gradually pale 

 brownish flesh color.

 from vent to tip of tail, 59 mm. ; from snout to ear-opening, 10 mm. ;
