FIGURE 7. Cephalic glands of Hydrodynastes bicinctus (MNRJ 4769). Lateral view after removing the skin (A), lateral view after removing the orbit, Duvernoy's gland and adductor externus medius (aem), adductor externus superficialis (aes), and levator anguli oris (lao) muscles (B), and ventral view exposing infralabial and sublingual glands (C). Duvernoy's gland = D.g; supralabial gland = s.g.; nasal gland = n.g; premaxillary gland = p.g; Harderian gland = H.g.; lateral sublingual gland = l.s.g.; medial sublingual gland = m.s.g.; infralabial gland = i.g. Scale = 5 mm.
