1,276 adult Indian skulls were examined for the incidence of the metopic suture. It was observed that metopism was present in 2.66% of the skulls and metopic sutures were present in 38.17% of the skulls. The metopic suture was present in the lower part of the frontal bone in various shapes in 35.27% of cases. The incidence in the upper, upper middle and lower middle parts of the frontal bone is 0.8% in each type. Besides the above-mentioned findings a peculiar type of shape was seen in 0.63 (inverted y) and a radiating type in 0.31% of the skulls.
