SUMMARY 1. The thresholds of taste for phenylthiocarbamide of samples of fifty subjects each of the Kintak Bong division of the Negritos and the Semai division of the Senoi have been estimated. The distributions of the threshold values, corrected for the effects of age and sex to the basis of the 32‐year‐old male as standard'subject, have been examined. 2. The so‐callednon ‘non‐taster’:‘taster’ ratios were found to be 0–18:0‐82 for the Kintak Bong Negritos and 0–04:0‐96 for the Sēmai Sēnoi, a difference of appreciable statistical significance. A difference of appreciable statistical significance was found also between the variances of the ‘taster’ fractions. 3. The distributions of values for these samples were compared, also, with those for samples of other ethnic groups, in respect of the ‘non‐taster’:‘taster’ ratios, the means of the ‘taster’ fractions, and the variances of these fractions. There appears to be a close correspondence between the distributions for the Sēmai Sēnoi and the southern Chinese. Comparison of the Kintak Bong Negrito material with that obtained by Barnicot (1950) for a group of African subjects failed to establish any recognizable affinity between these two ethnic groups.
