Ventrals large, one-third to more than half the width of the body; nostrils lateral; nasals separated by internasals; 21-25 longitudinal rows of imbricate scales at midbody; an azygous prefrontal shield usually present; rostral undivided;

Body subcylindrical, only slightly compressed. Rostral higher than broad; an azygous shield separating the prefrontals, sometimes absent; frontal considerably longer than its distance from the end of the snout; 1 pre- and 2 post oculars ; 7-8 supralabials, the 3rd-4th touching the eye temporals 1+2 ; five infralabials in contact with the genials, both pairs of which are usually well developed and in contact with one another, the anterior pair smaller than the posterior ; a double series of elongated scales, the inner series the larger, at the oral margin. Scales in 21-23 rows (rarely 25). Ventrals 213 to 245, about four times as long as broad. Caudals in males 37-47, females 29-35 (Smith 1943:443).

Total length: males 875 mm, females 1420 mm; tail length: males 130 mm, females 145 mm.

In colour these snakes are light or dark bluish grey above, yellowish below, with black bands more or less of uniform width throughout or narrowing on the belly (some of them interrupted below). Upper lip yellow. Snout yellow, the colour extending backward on each side of the head on each side of the head above the eye as far as the temporal shields, leaving a dark bar in between.
