The existence of variations in plant or animal life is the factor that facilitates the work of the biologists towards the isolation of the more useful varieties for purposes of further improvement. Newton (1917), Ghosh (1936) and Ramachandran (1937) have recorded about the larger honey storing capacities, their darker colour and larger size of some hill varieties of Indian bees. Even in the varieties found in the plains, the present author has observed certain colonies showing remarkably desirable characters, such as mild temper, minimum swarming propensities, larger honey gathering and stamina to resist unfavourable seasonal conditions. Ramachandran (1937) has also made mention of the different "idiosyn-cracies" of the various hives in an apiary. A detailed study of the biometric variations, if any, that differentiate bees possessing diverse characters has not so far been made in India.
