AbstractThe skin of the mole (Scapanus townsendii) has the following characteristic features. (1) The epidermis is thin over the general body surface and very thick on the palms and muzzle. On the snout the epidermis has the specialized end‐organs of Eimer. (2) The dermis has no papillary body, and few elastic fibers, except in the eyelids where elastic fibers are more numerous. The arterioles in the deep dermis are surrounded by nerve filaments which are positive for alkaline phosphatase.
