✦ Synopsis

During development ofXantho bidentatus, ten stages of the eggs have been recognlsed. In this period the colour of the egg changes from black to pale white at the X stage of development. Total carbohydrate, glycogen, soluble protein, insoluble protean, total lipid, ash and water content have been determined in all ten stages of developing eggs. The utlllsation of these compounds at various stages of development is discussed. The habitat of the crabs and its significance during development is also discussed A constant decrease in the organic material as well as the dry wexght of the egg was noticed with increased stage of development. Along with this a steady increase m the water and ash content was also observed. Glycogen was reduced during early days of development, whereas hpid was reduced during the latter stages of development. Both soluble and insoluble proteins exhibit conspicuous variations dependmg upon the stage of development.
