The finger pattern and the finger ridge counts were investigated III 48 cases of Klinefelter's syndrome. The finger pattern of all the digits in this particular syndrome were similar with those in the normal female controls. If compared with the normal men, the ulnar loops were frequent and the whorls were infrequent both with statistic significance. In Klinefelter's syndrome, the arches of the thumbs and the ulnar loops of the index fingers were frequent, and the whorls of the index fingers were infrequent compared with the normal male and female controls with statistic significance. The loops and whorls seen in Klinefelter's syndrome showed ridge-counts less than the control subjects. The total finger ridge-counts were significantly less than those observed in the normal male and female subjects probably due to over-all decrease of the ridge-counts of the finger-prints rather than increase of the arches. The Japanese with Klinefelter's syndrome seem to have the common dermatoglyphic findings with the caucasian people with this syndrome in the finger-prints similar with the normal women, predominance of the fingerprints with less ridge-counts and the total finger ridge-counts less than normal female subjects.
