Internasals and prefrontals small irregular. Labials 15 to 16, two 
to three rows of scales between them and the orbit. Scales in 25 
(28 to 27) rows. Ventrals 168 to 177. Subcaudals 22 to 25. Light 
brown, tinged with yellow or ash, darker posteriorly. Irregular 
rhomboid dark-bordered areas of the ground color or darker form a 
vertebral series. Posteriorly the spots become transverse bands. 
Outside of the dark borders there are more or less indistinct lines of 
light color which cross on the flank inclosing a similar small spot on 
the lower part of the side opposite each of the dorsal series. Of 
spots and bands there are about forty to the series. A light line 
crosses the frontals, and passes through the supraciliary to the poste- 
rior labial. Another line of light color passes in front of the eye, 
and includes the lower portions of the labials. The dark colors are 
darker and the light whiter than those of confluentus.
