Body strongly compressed. Scales in 17 to 19 rows, with an 

 apical groove. Anal entire. Loreal higher than long. Ona 

 prseocular. Two postoculars. 8 upper labials, the third, fourth 

 and fifth entering the orbit. Colour pale reddish olive with a 

 series of round brown spots, pale within and bordered without 

 with white, and down each side of spine with a row of smaller and 

 less distinct spots alohg the side. Head symmetrically marked.

Inhabits Pegu, Tenasserim, the Malayan Peninsula, Siam, 

 Pinang, Java, Celebes, and, according to Gunther, China and Bengal. 

 The last locality, however, I doubt, and it requries strong confirm- 

 ation. This is a common species in Pegu, and the handsomest of 

 the genus, I think.
