Rhinophis

R. blythii

Blyth's Earth Snake

Sri Lanka

TL 37 cm

Head details: snout acutely pointed ; rostral very slightly compressed, about one third the length of the shielded part of the head; frontal longer than broad. Diameter of body: 22-32 times in the total length. Scalation details: 17 scales round the middle of the body, 19 behind the head. Ventrals: only a little larger than the contiguous scales, 148-162. Subcaudals: 4-7. Tail: caudal disk one half or three fifths the length of the shielded part of the head ; some of the distal caudal scales with faint traces of keels. Coloration: dark brown; sides with vertical yellow spots or a festooned or zigzag band along the anterior half of the body; a yellow ring round the base of the tail. [SOURCE: Boulenger]
