Abstract
1. Electron microscopy, infra-red analysis and histochemical techniques have been used to determine the site of pigment deposition, the cellular localisation of pigment and the type of pigment precipitated in the egg shells of quail, White Leghorn, Brown Ranger and Black-Headed gull. 2. Transfer of pigment occurs via the surface epithelial cells of the shell gland. 3. Porphyrins are probably synthesised in the blood. 4. Possible pigment deposition mechanisms are discussed.Entities:
