NO. 1174. HAWAIIAN LAND UEVTILES—STEJNEGER. 809 



frontal long, in contact with two auterior snpraoculars; four large 

 supraoculars j eight supraciliaries; frontoparietals and interparietal 

 fused into a large shield in contact with frontal, second, third, and 

 fourth supraoculars, though only very narrowly with the second, some- 

 what longer than frontal: parietal broadly contiguous behind fronto- 

 parietal (abnormally fused together in the present si)ecinien), followed 

 by a single large pair of nuchals in contact; first loreal in contact Avith 

 postnasal, supranasal, frontonasal, prefrontal, second loreal, and second 

 supralabial, higher than wide; second loreal hirger, wider than high, 

 in contact with second and third supralabials, and behind with two pre- 

 oculars, of which the lower is the larger; eight supralabials, sixth and 

 seventh much higher than the others, fifth very wide, twice the width 

 of the anterior ones, bordering the whole lower edge of the orbit (abnor- 

 mally divided in two on the right side of the present specimen); lower 

 eyelid with a large transparent disk; ear-opening oval, small, about the 

 size of the anterior supralabials: mental nearly straight behind, fol- 

 lowed by a single unpaired postmental; eight narrow infralabials, of 

 which the first is very small, triangular, aiid barely touching the post- 

 mental; thirty rows of smooth scales around the middle of the body, 

 those on back and underside of uniform size and larger than those on 

 the sides; scales in front of anal opening somewhat enlarged; toes 

 underneath not covered with regular scales like those on top except 

 under the more compressed portion near the tip, but with a regular 

 series of very numerous transverse corrugations; tail underneath, 

 with a regular median series of transversely enlarged scales. 



Color. — Scales on upper parts narrowly edged with dark brown form- 

 ing a regular network, the six median dorsal rows of a bronzed tawny 

 olive, those on the sides more dark brown forming a broad dark band 

 from behind the eyes to the root of the tail ; top of head like back, 

 interparietal and parietals each with a large ill-defined brown spot 

 occupying most of the shield except the margins; underside of body 

 paler than the back and more greenish, the throat with dusky margins 

 to the scales; tail like upper surface becoming dull dark bluish on 

 the i)osterior half. 



Dimensions. — Total length, 120 mm.; snout to vent, 43 mm.; vent to 

 tip of tail, 83 mm.; snout to ear-opening, 11 mm.; greatest width of 

 head, 7 mm.; axilla to groin, 22 mm.; fore limb, 15 mm.; hind limb, 

 21 mm. 



Variation. — The arrangement of the head shields offers but few 

 variations in the specimens before me; the number of scale rows 

 around the body is somewhat varying, however, as in Nos. 23449, 23452, 

 U.S.N.M., for instance, I count twenty eight rows. In most of the speci- 

 mens there are a couple of minute knobs or lobes in the anterior border 

 of the ear opening, but these are indistinguishable in the specimen 

 described. 



As to coloration there seems to be three distinct stages according to
