Java: Buitenzorg, 7 spec. 



Upper labials flve; the first pair of lower labials in contact with 

 each other ; there is no azygos shield in contact with the anterior chin- 

 shields. Vertkal shield six-sided with an obtuse anterior angle, and 

 the posterior angle almost a right one. The thirdand the fourth upper- 

 labial in contact with the eye. One posterior and one anterior ocular 

 shield. The number of ventrals varies from 157 — 167, that of the 

 pairs of subcaudals from 16—28. One of our specimens has 179 ven- 

 trals and 16 pairs of subcaudals. 



Upper part blackish, head somewhat lighter, rostral shield of a 

 lead-colour, the lower part of the upper labials whitish. The lower 

 part of the head whitish with a dark, longish, irregulär spot on every 

 shield. Ventrals and subcaudals of a light colour with two crescent- 

 shaped dark spots, placed side by side with the convex side behind. 

 These spots regularly arranged two on every ventral do not meet on 

 the middle of the belly. On the anterior part of the tail the dark 

 spots on the subcaudals leave a light Space about the region of the 

 subcaudal line ; lower down these spots increase so much in size that 

 the underpart of the extremity of the tail is of a dark colour. 



This species is closely allied to C. nigra albus Gthr. which has the 

 lower parts of a uniform whitish colour, and to C. modesta D. et B. 

 which has one crescentshaped dark spot on the ventrals, and a black 

 subcaudal line.
