Larvae have an adepidermal membrane (= basal lamina, basal membrane), enclosing an adepidermal space and lamellated bodies (Nakao 1974), underlying the epidermis (Salpeter and Singer 1959). The basement lamella (about 3–4 µm wide) is a series of alternating layers of collagen fibrils arranged in a criss-crossed or orthogonal manner (Weiss and Ferris 1954, Leeson and Threadgold 1961, Fox 1972) (see Fig. 1). Anchoring filaments from the epidermis cross the adepidermal space to the membrane, and large anchoring fibres from the latter traverse the basement lamella (Chapman and Dawson 1961) to join collagen around muscle tissue (Fox 1976) (see Fig. 2). A basement lamella is present in body dermis of the larval Ichthyophis kohtaoensis (Welsch and Storch 1973).
