Description
Gloyd and Conant (1990) state that the only male they examined was 37.4 cm (14.7 in) long with a 5.4 cm (2.1 in) tail. The largest female was 49.8 cm (19.6 in) in length with a tail of 5.9 cm (2.3 in). The body is relatively slender, although adult females are more stout. The snout is rounded, while the head is not markedly wider than the neck.
Scalation includes 6 supralabial scales, 19 rows of keeled dorsal scales at midbody, 140 ventral scales, a single anal scale, and 32 paired subcaudal scales.
The coloration consists of a black, dark brown, or dark gray ground color, with almost no discernible pattern. Exceptions to this rule may have labial scales with a whitish border along the line of the mouth, a few whitish subcaudal scales at the tail tip, or a faint hint of a dorsal pattern.
