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.
