Colour: Body and tail dark brown; upper part of head and sides brown as far as the inferior margin of the orbit; irides--; upper jaw, chin, throat, under parts of abdomen and tail, light straw colour-the latter mottled with brown.
Abdominal scuta 158 : subcaudal 28.
This species very much resembles the C. fuscus, for the young of which it might be taken; it differs from it, however, in the form of the head, which is much more depressed, and in the arrangement and form of its plates; the tail also is much shorter.” (Hallowell 1845, plus dimensions, not given here)
