present. One preocular. Two or three postoculars. Tem- 
porals normally two followed by three, sometimes 2+4. 
Seven (rarely eight) superior and nine, 10, 11 or 12 inferior 
labials, fifth and sixth superior and fifth inferior usually 
largest, third and fourth superior reaching eye, first pair of 
inferior meeting on median line. Genials in two pairs, 
anterior larger than posterior. Scales on body smooth, thin, 
imbricate, usually in 23, sometimes 25, rows. Anal plate 
not divided. Gastrosteges varying in number from 216 
to 235. Urosteges in two series of from 71 to 79. 
The snout is yellowish white, unmarked or slightly 
spotted. The middle third of the head is black. A yellow- 
ish white band crosses the back of the head, involving the 
tips of the parietal plates, and joining the white of the 
throat. Behind this white one is a half ring of black, fol- 
lowed in turn by another of red. The whole body is similarly 
marked, being encircled by from 39 to 47 white rings* be- 
tween which are rings of black more or less divided and 
replaced by blotches or rings of red or pink. The propor- 
tion of black to red varies greatly in different specimens, 
as does also the intensity of the red. The colors of the 
back and sides are continued, somewhat irregularly, onto 
the lower surfaces. The white rings are little if at all 
broader on the sides than on the back.
