First use of present combination. CONTENT. Carphophis vermis is monotypic. DEFINITION. Adults have total lengths of 17.7-39.1 cm; males are 17.7-35.4 cm long, females are 24.0-39.1 cm. The cylindrical body has a plain dark gray to gray-violet dorsum, MAP. Distribution of Carphophis vermis: circle marks the type locality, and a pinkish venter. The pinkish ventral pigmentation extends dots indicate other selected localities,and stars indicate fossil localities. upward on the sides to include the third lateral scale row. The head is pointed, and the eyes are small and violet. The short tail ends in a blunt spine-like scale. Dorsal body scales are smooth, pitless, opalescent, and normally occur in 13 rows. On the venter are 120-150 ventral scutes, 2141 subcaudal scales, and a divided cloaca1 scute. Each side of the head has I nasal, I loreal, 0 preoculars, 1 (rarely 2) postocular(s), I + I(rarely I + 2) temporals, 5 supralabials, and 6 infralabials. Dorsally, the paired internasal scales and prefrontal scales are separate (not fused). The chin lacks gular shields between the posterior chin shields. The single hemipenis is 5-7 subcaudals long when inverted. It has a forked sulcus spermaticus, a calyculate crown, numerous small spines on the shaft. and three large basal spines. The FIGURE.
