PHYSICAL DESCRIPTION: The costal grooves number 20-23 and the dorsal band is narrow, poorly developed and scarcely lighter than the adjacent sides. The dorsal surfaces have minute silvery-white and bronze flecks. The belly is dark and the throat is somewhat lighter, mottled. The intercostal folds be- tween the toes of the appressed limbs number 9-10. The length is up to 30 mm *1009*. Some specimens have red pigment on the cheeks, front legs, and an- terior sides of the body *1014*.

REPRODUCTION: The eggs laid in damp logs and moss *883*. There are 2-4 hatchlings per clutch. The hatchlings lack gills and are approximately 25 mm long *1014*. They have biennial cycles, wherein the female requires nearly 2 years to form a new egg complement following egg deposition. They deposit the eggs in early summer, and courtship is primarily in the spring months. Some males reach sexual maturity at end of the 2nd summer, and the females at 3 years *883*.

In the spring and fall large numbers occur under thin, flat rocks on or partly in the ground *1014*. They also occur in leaf mold *1009*. This species avoids dry ridge crests and excessively moist habitats such as stream margins *949*. It dwells on upland slopes and is found in caves *884*. It hibernates and aestivates deep underground *1009*. This species will forage at night beneath rocks and logs *895*.
