* My supposition that this snake is identical with D. ater has proved to 
be quite incorrect. (Col. Snak. p. 127.) 
+ The specimen formerly referred to this species is different, but in so 
bad a condition that its determination is almost impossible. The diagnosis 
of the species (Col. Snak. p. 171) is partly incorrect, there being a series 
of white spots along each side of the belly, and not of black ones. The 
lateral edges of the vertical are convergent. 
{ Frontals sometimes united into a single pair.
