    Description

    Eye moderate; rostral just visible from above; suture between the internasals as long as that between the pre-frontals or shorter; frontal longer than its distance from the end of the snout, shorter than the parietals; loreal longer than deep ; one preocular (sometimes divided); two or three postoculars; temporals 1+1, or 1+2, or 2+2; 8 upper labials, third, fourth, and fifth entering the eye; 4 or 5 lower labials in contact with the anterior chin shields, which are much shorter than the posterior chin shields.

    Dorsal scales in 19 rows, faintly or feebly keeled. 177-235 ventrals; anal divided; subcaudals 75-107, also divided.
