(B) Frontal sections through the spiracular region, above the closing lever, and cutting the two dorsal closing bars. These show how the spiracle closes when the closing bars are pushed against the closing bow or atrium.

(C) Apparatus viewed from the inside with the scolopophorous organ and part of the elastic opener removed. Only part of the spiracular tracheal manifold is shown. The valve is open.
