H. platyceps has the following characteristics: 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.
Olive-brown above, with small black spots; frequently two black parallel lines or an elliptic marking on the nape; a light, black-edged streak on each side of the head, or a black line from eye to gape (corner of mouth); belly yellowish, with or without blackish dots; frequently a black line or series of elongate blackish spots along each side of the belly; lower surface of tail frequently mottled with blackish; throat sometimes black. In life, a coral-red band is said to run along the ends of the ventrals.[3]
