✦ Synopsis

The occlusal surface pattern of the lower molars and the second deciduous molar among the Polynesians living i n Western Samoa was studied on plaster casts. The following are the characteristic traits of this race. The occlusal surface pattern of the first and second lower molars falls within the range of variation of the Mongoloid racial group. I n general, the variation of the furrow pattern is remarkable, but the tendency of reduction of number of cusps is not conspicuous.

The frequency of C6 in the lower molars and C7 i n rn2 is far higher than in any other population, but the frequency of C7 in MI or Mz is not noticeably differ en t.
