Within is a chamber about two feet high and six feet across, well above water and provided with a ventilator through the roof, also two entering passages under water, one winding for ordinary traffic, and one straight for carrying in wood, whose bark is a staple food.

On each side of the lower surface, or foot, there is a broad membrane, which appears sometimes to act as a ventilator, in causing a current of water to flow over the dorsal branchiae or lungs.
