Webs sometimes occur as a congenital defect of the human fingers or toes. The relatively largest webs are those of the bats' wings. In birds the extent and special character of the webs (technically called palamæ) are taken into some account in classification, and some conditions of the webs receive special names. See web-footed, and cuts under bat, duckbill, flying-frog, Œdemia, otary, palmate, semipalmate, and totipalmate.
• noun In coal-mining, the face or wall of a long-wall stall in course of being holed and broken down for removal.
