In the Turtle the glands excrete at the base of the neck; in the Kinosternon a gland is situated near the fore and hind margins of the side-walls, uniting the carapace and plastron: the duct perforates the bone, and opens by a fine slit in the wall. In the Crocodilia a small sinus is formed bj^ an inward fold of integument near the inner side of the mandibular ramus, into which sinus opens the dilated duct of a gland, which is surrounded by a muscle, detached from the back part of the pharynx, and proceeding along the outer side of the ceratohyal to expand upon the gland and reservoir.' Cuvier^ describes its contents as being unctuous, of a dark grey colour, with a strong nmsky odour. XX. vol. iii. p. 272; prep. no. 2106. XII. torn. y. p. 252 (1S05)..
