and ear-opening, the diameter about one-half its distance from ear- 

 opening, which is roundish and smaller than the larger supralabials; 

 mental i)entagonal narrow, scarcely as wide as the nearest infralabials; 

 nine larger infralabials; the scale rows adjoining the infralabials con- 

 siderably larger than the granules covering the throat, and more or less 

 hexagonal, especially the pair behind the mental, but not clearly differ- 

 entiated as chin-shields, merging by degrees into the grannies; body 

 and legs above covered with small uniform granules barely larger than 

 those on head; throat with granules of the same size, but the rest of 

 the underside with imbricate scales two to three times larger than 

 dorsal granules; scales on preanal region somewhat larger, nonimbri- 

 cate, more or less liexagonal; an angular series of eight of these, the 

 angle pointing backwards, with obscurely developed pores. Join a sim- 

 ilarly modified series of eight scales on the proximal half of each thigh, 

 together twenty-four obscure pores; lingers and toes free, all except 

 inner ones (which are otherwise well developed) with a compressed 

 clawed joint adhering to the dilated basal portion; the distal part of 

 the latter underneath provided with seven to eight pairs of lamelhe; 

 tail flattened underneath, with a sharpish edge, and covered with 

 small scales, somewhat larger rnferiorly (proportion as 10 to 7), which 

 show a slight though perceptible verticillate arrangement every tenth 

 or eleventli scale row above and every sixth or seventh below, being a 

 trilie larger than the others and emphasized on the lateral edge by a 

 slightly enlarged spine-like scale imparting a light denticulation to 

 the edge. 



Color above pale drab with a few scattered blackish dots of which a 

 pair at the base of the tail is most conspicuous; hea<l with obscure 

 brownish raarblings, the labial sutures being also marked with brown; 

 a band of similar color and white-edged above from snout through eye 

 to above the ear; underside white; the terminal portion of the dilated 

 part of the digits dusky; tail like body, with alternating pale-brownish 

 irregular cross bars above. 



Dimensions. — Total length, 85 mm.; snout to vent, 38 mm.; vent to 

 tip of tail, 47 mm.; snout to ear-opening, 9.5 mm,; greatest width of 

 head, 8 mm. ; fore leg from axilla, 11 mm.; hind leg from groin, 14 mm.; 

 from axilla to groin, 18 mm. 



Variation. — All the specimens examined by me agree very closely in 

 structure with the specimen described above. One specimen (No. 23504, 

 U.S.N.M.) has the tail reproduced. It is much shorter. Hatter, and 

 broader at base, the scales rougher and not arranged in regular trans- 

 verse series. As a curiosity, it may be mentioned that the tij) of this 

 tail is bifurcate for a distance of about 3 mm. 



The chief variation is in the coloration. In some specimens black 

 spots are nearly absent above, while in others they are more numerous. 

 Thus in a specimen which I collected in Honolulu (No. 23508, U.S.N.M.) 

 there is from the shoulders to the base of the tail a double series of
