Description

Adults may grow to more than 100 cm in length. Gloyd and Conant (1990) reported that the largest specimens they saw were from Pisté, Yucatán: a male of 105 cm with a missing tail tip and a female of 101 cm. The average tail length is 19.2% of total body length in males and 16% in females.

Scalation includes 23 rows of keeled dorsal scales at midbody, 131-141 ventral scales and 46-62 subcaudal scales, most of which are paired, especially towards the tail tip.

The dorsal color pattern consists of light brown to deep reddish brown ground color overlaid with 12-18 broad brown or brownish crossbands. Laterally, these crossbands are more lightly colored in the center and usually contain one or two dark spots. The head is clearly marked on either side with two longitudinal light lines: the upper one is narrow and may be broken behind to the eye, while the lower one is wider and separated from the commissure by a dark band.

Common names

Yucatecan cantil. Mayan names for this species are "wol-poch" (Gaige, 1936) and "uol-poch" (Schmidt and Andrews, 1936).
