Qualitative evaluations of buccal smear specimens have indicated an unusually high incidence of triple-X females in a hospitalized schizo­ phrenic population. Specimens from adult prisoners have also indicated an unusually high incidence of triple-X females. Studies of a population of confined juvenile offenders, on the other hand, have indicated an unusually high incidence of one-X females. No unusual indications were observed in a population of "normal" volunteer females. The data and their implications are discussed in context with previous observations.
