Explanation of plate XIII. Fig. 1. Dermatonotus Mülleri BTTG. Sternal apparatus (X 2). pc = procoracoideum. c — coracoideum. ec — epicoracoideum, st — sternum, sc — scapula. Fig. 2. Dermatonotus Mülleri BTTG. Last phalanx (X 10). Fig. 3. Dermatonotus Mülleri BTTG. Cross-section through the skin (X 50). ep — epidermis, ps = superior pigment-row, g = glandulous layer, ch = chromataphor-cells, eth = epithelium of the glands, pi = inferior pigment-row, cs

1 — undulated fibres and cs- = horizontal fibres of the coriuin. v — bloodvessels, o = opening of the gland on the epidermis. Fig. 4. Chiasmoeleis albopunctata BTTG.
