Notes	The pigment accumulation in the shell gland through an ovulation cycle and the pigmentation onto the surface of egg shell were observed in Japanese quail. The pigment granules and PAS-positive material in the apical cells of the epithelium of the shell gland increased progressively as time elapsed after ovulation and decreased suddenly 2-3 hrs before the expected oviposition as the pigmentation onto the egg shell occurred. The pigment granules and PAS-positive material secreted from the cells gathered to form pigment masses between folds of mucous membrane. The pigment masses were deposited on the surface of egg shell. After the pigmentation, only the PAS-positive material was seemed to be deposited on the surface to complete the cuticle.
