Abstract
The three cells which make up Verson's glands in Calpodes undergo drastic changes as they produce the cuticular linings and the secretions of the glands. The duct cell secretes only the typical cuticular duct. The saccule cell produces both the atypical cuticular saccule and dense granules which are discharged just before ecdysis. The secretory cell is much enlarged by vacuoles which remain separate until they too are discharged before ecdysis. Dense granules are also produced by the secretory cell. During deposition of the cuticular duct and saccule, their lumina arc packed with cell processes containing microtubules, which appear to arise from centrioles. Isolation and residual bodies appear in both the saccule and secretory cells even before discharge of their secretions.
