C
starts withThe type series consists of three specimens. The holotype is an adult male measuring 259 mm (10.2 in) in total length. One paratype is a female, either maturing or mature, measuring 207 mm (8.1 in), whereas the other one is poorly preserved and of unknown sex, measuring about 365 mm (14.4 in). The body is dorsoventrally flattened and 8–11 mm (0.3–0.4 in) wide. There are 95–101 primary annuli (segments). The head is bluntly rounded. The eyes are dorsolaterally oriented and covered by epidermis. The coloration is relatively uniform, slate gray dorsally and slightly lighter ventrally. There are numerous whitish skin glands present throughout the body. The specific name perissodus refers to the high number of premaxillary-maxillary teeth compared to other Chthonerpeton and is derived from Greek perissos (=more than the usual number of) and odous (=tooth).
