thirds times in distance from snout to vent; the adpressed Hmbs 

 overlap by about half the length of the fingers; sole of hind foot with 

 two somewhat irregular series of enlarged tubercles from heel to base 

 of third and fourth toes; tail with a series of transversely enlarged 

 plates underneath. Color (in alcohol) above nearly uniform olive, 

 head more clay color (in life probably red), underneath whitish.

The type described above is in very poor state of preservation and 

 is probably a female. A fully adult male in excellent condition 

 (U.S.N.M. No. 34080) from Ishigaki shima agrees in all essential 

 details with the type, except that the head is considerably more 

 swollen at the temples. This specimen measures: Total length, 

 357 mm.; snout to vent, 159 mm.; vent to tip of tail, 198 mm. ; 

 snout to ear, 39 mm. ; greatest width of head, 34 mm. 



I find in none of these specimens any specially differentiated, keeled 

 scale behind the vent near each corner as in Eumneces latiscutatus and 

 its allies. 



The half-grown specimens have a median dorsal pale band bordered 

 with dark-brown lines, a dorso-lateral whitish stripe on each side 

 similarly bordered above, and with a broad brown lateral band, 

 below which again a whitish line. 



A young specimen (Science College Museum, Tokyo, No. 35), from 

 Iriomote shima, measuring 60 mm. from tip of snout to vent, differs 

 in having the frontal shield somewhat broader in front than behind. 

 The stria> on the dorsals show almost as plainly as in the adult. It 

 has three pairs of nuchals, but is abnormal in lacking a postnasal. 

 The coloration is indicated below. 



Variation. — I have six very large adult and adolescent specimens 

 before me, two from Ishigaki shima, two from Iriomote shima, and 

 two from Miyakoshima. In scutellation they are practically identical, 

 and the postnasal is present and well developed in all. Its presence 

 may therefore be regarded as normal in this species. Five of them in 

 addition have three nuchals, three specimens have them on both sides, 

 two on one side, while the sixth has two only on both sides (No. 34081) ; 

 there is conse([uently reason to l^elieve that three ])airs is the normal 

 number. In addition to these fidl-grown and nearly full-grown speci- 

 mens, there is a seventn, quite young, black with yellowish stripes. It
