The i)roximal ends are small and articu- late with tin ;|i(.ndniL; carpal ami metacarpal bones. The distal end is relatively large; its articular surface is coiidylind in front, trochlear fjehind. Each chief digit comprises three phalanges and three sesamoids. The bones of the cliief thgits reseml)le tliose of the o.\ in furm, but there is no foramen on the interdigital sitle of the extensor process and the proximal .sesamoids are narrow and ridged behind. The phalanges of the accessory digits (which do not reach the groimd ordinarily) are similar in form but much smaller. Fusion of the proximal ends with the shafts takes place at about two years for the first phalanges, at about one vear for the second iihalanges.
