and interparietal together ; frontal in contact with the second supra- 

 ocular (in one specimen in contact with the second and third supra- 

 oculars) ; four supraoculars, second largest ; normally six supra- 

 ciliaries, first largest (in one specimen there were six supraciliaries 

 on one side and seven on the other, another specimen had only 

 five) ; frontoparietals distinct, as long as or slightly shorter than 

 the interparietal, AA'hich entirely separates the parietals, except in 

 one specimen, where they just touch each other behind the inter- 

 parietal ; a pair of nuchals ; four labials anterior to the subocular, 

 which is large and not narrowed inferiorly. Ear-opening oval and 

 oblique or nearly round, as large as or a little larger than a lateral 

 scale ; no projecting lobules. 28 scales round the middle of the 

 body in fourteen specimens, 30 in four specimens ; dorsals very 

 slightly larger than the remainder ; dorsals distinctly bicarinate 

 in seven specimens, feebly so in one specimen, distinctly tricarinate 

 in two specimens, and in the remainder some are bi- and some 

 tricarinate, the keels being either distinct or indistinct ; ventrals 

 very feebly bicarinate or smooth. The hind-limb reaches the elbow 

 of the adpressed fore-limb. Subdigital lamellae smooth, 24 to 2G 

 under the fourth toe. 



Colour (in life). Above bronze-brown, the back generally uniform 

 and immaculate, but sometimes with five more or less distinct 

 narrow longitudinal black lines ; along each side from behind the 

 eye to the basal part of the tail a broad black or dark brown line, 

 2^ to 3 scales wide (in two specimens this dark line was sparsely 

 dotted with light bronze), separated from the bronze back by a 

 narrow, sharply defined, pale yellow line, one scale wide. Labials, 

 sides of neck and body pale sulphur or greenish yellow, usually 

 sharply defined from the dark lateral line above, but in a few 

 specimens spotted viith dark brown. Lower surfaces pale or bright 

 emerald, or yellowish green. 



Size. Total length 330 mm. (snt. to vnt. 116 mm. ; tail

Localities. Of this skink, which does not seem to have been 

 previously recorded from either the Malay Peninsula or Siam, I 

 have seen twelve specimens. One I got in the Larut Hills, Perak, 

 elevation 1000 feet ; one I caught in the jungle of the Dong Phya
