Upper labials five; the first pair of lower labials in contact with 
each other ; there is no azygos shield in contact with the anterior chin- 
shields. Vertical shield six-sided with an obtuse anterior angle, and 
the posterior angle almost a right one. The third and 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, irregular 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 hght 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. nigro-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.
