Beneath are 109-150 ventrals, 21-41 subcaudals in two rows, and a divided cloacal scute. They normally lie in 13 rows throughout, but rarely occur in 14 or 15 rows near the vent. Body scales are smooth, pitless, and may be somewhat opalescent. The tail is short, and ends in a blunt, spine-like scale. It is bluntly pointed with small black or violet eyes, and lacks any markings. The head is small and depressed, and not wider than the neck. The unpatterned venter is pinkish to salmon-colored, with the pigment extending upward onto the lower sides. Dorsally, the body is uniform gray, gray-brown, gray-violet or dark brown juveniles are darker than adults. In the skull, the premaxilla is enlarged, the nasal bones arc expanded dorsally, and the quadrate is shortened. Those anterior have a well developed hypophysis. Each trunk vertebra has a long, narrow centrum with a long, low neural arch lacking epizygapophysial spines a long, low neural spine a normally spatulate (broad and round) to cuneate (as opposed to oblanceolate) haemal keel and short, thick, flattened, prezygapophyseal accessory processes. Snakes of the genus Carphophis are slender, cylindrical, relatively short (maximum total length 39.1 cm, Conant and Collins 1998), terrestrial, semifossorial, worm and slug predators. Holotype: unlocated (neither ANSP nor USNM), a 261 mm specimen.
