PHYSICAL DESCRIPTION: This species is black above, with a red patch on the side of the head and the lower sides and belly dull bluish-gray. The throat is anteriorly flesh colored and the costal grooves number 15-16. There are 2-3 intercostal folds between the toes of the appressed limbs. The length is up to 135 mm *1009*.

REPRODUCTION: This species will nest in the fall *1014*. They court slowly and deposit a single spermatophore. There is a complex courting behavior with a high success for each spermatophore. The male chases rival males away from the female and courtship usually occurs at night between dusk and dawn but may occur during the day under cover. The olfactory system is probably important to courtship *951*. Courtship and spermatophore deposition take place in August and September; it is believed that eggs are laid underground during summer or late fall and that the young emerge the following spring *10812*. This species will reach sexual maturity at 3-5 years *3915,918*.

BEHAVIOR: This species is abundant in and beneath old rotten, moss-covered logs and bark and more rarely, beneath stones and slabs of rock, on heavily forested slopes *1009*. This species inhabits the forest floor and is active on the surface at night when the humidity is high and temperatures are mild. During the day it occupies burrows under stones and logs, or tunnels formed by rotted roots *1014*. This species is normally found above 3000 feet. They do not migrate during the breeding season and members possess an ability to home. They are found in subterranean passages *944*. And 2 of 7 subspecies exhibit an apparent aposematic coloration *924*. Population parameters: The annual survivorship is 0.38-0.57. This species lives to be no more than 7 years old *3915,918*.
