I collected only two specimens of tliis species, one at Prome on tlie Irawady, and 

 the other at Ava on the same river, in Independent Burma. 



The measurements of the Ava specimen are as follows : Length 7 inches. Head 

 0-17 ; gape 0-17 ; taU 0-25. 



It has 216 ventrals and 7 sub-caudals. The scales are ranged in nineteen 

 longitudinal series ; the ventrals are nearly twice as large as those on the vertebral 

 line. The vertical is much longer than broad and smaller than the superciliary. 

 The occipitals are a little smaller than the vertical and are rounded behind. The 

 nasals are more than half the size of the frontals. There are six upper labials, the 

 third and fourth entering the orbit. Temporals 1 + 2 + 2. 



In colour it is uniformly irridescent bluish-black, with pale yellow bands 

 across the back, but not extending on to the belly and frequently interrupted on the 

 back. Another series of smaller and more indistinct yellow bands along the sides 

 of the belly, alternating with the dorsal bands and not prolonged on to the sides of
