The rhesus monkey, Macaca mulatta and the langur, Presbytis entellus were observed around four Indian cities, more particularly at Jaipur. The former lives near human dwellings but the latter are found on the outskirts of the cities. Fluctuations in the numbers of rhesus of various age groups have been discussed. The critical size of a Macaca troop appears to be 50 to 70 individuals. Macaca overlord allows subleaders in its troop but langurs do not tolerate any sexually potent male in the troop. Differences in the modes of splitting of the troops in both the species of monkeys have been described. Observations on the mating behaviour of rhesus have been made. Monkeys breed twice a year and have definite breeding season.
