 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 triangulär black spot, these series of spots 

 form a continuous black line along both the sides of the belly.

 neck to the posterior temporal shields is missing in both of them, 

 whilst in the smaller specimen from Kotting scarcely a trace of the 

 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 13* and 14* ventral a black crossband
