Scales in thirteen rows. One praeocular, two postoculars, one lo- 
real, temporals 1 + 2 the anterior in contact only with the lower post- 
ocular. Upper labials seven, the third and fourth entering the orbit, 
the sixth is the largest and as long as the anterior temporal. Ven- 
trals 117; subcaudals 90. Upper parts dark brown, lower parts yellow 
without stripes or spots. Head and neck black with two white small 
spots on the occipitals. Three yellow cross-bands on each side of 
the neck, the first pair melting together across the back and 
forming a collar, the third not clearly visible. A yellow spot behind 
and under the orbit, the three anterior upper-labials partly yellow 
partly black. In each corner of ventrals and subcaudals nearest to the 
outer rows of scales there is a triangular black spot, these series of spots 
form a continuous black hue along both the sides of the belly.

black line running behind the eye is to be seen. Moreover the larger 
specimen from Sikka shows a very peculiar coloration along the sides 
of the body. Just above the IStt and 14tli ventral a black crossband
