A clutch of four fully-shelled oviductal eggs of Draco obscurus formosus. Note the pinched projections at both ends of each egg. shelled eggs. Length and width dimensions of such eggs change as they absorb or lose water through the soft parchment shell to produce changes in their size, shape, volume, and surface area. Consequently, soft- shelled eggs have to be measured in their oviducts or soon after they are oviposited. This is in contrast to rigid-shelled eggs of crocodilians, geckos, birds, and some chelonians which can be measured at any time after being laid. Iverson and Ewert (1991) applied Preston's (1968) formulation to describe reptile eggs firstly. This for- mulation was developed to describe the shape of avian eggs and assumed that an egg was axis-symmetric and the revolved egg outline on the x-axis gives its volume of revolution.
