In comparing the various racial groups, the Oroks and the Giliaks in Sakhalin are unusually interesting since they possess some characteristics on their palm patterns which do not resemble any other peoples.
In the Oroks, palmar main line D terminates most frequently in position 11 and line B commonly in positions 5 and 7 but some of these lines terminate in special position 9 (table 3). The most common main line formulae are 11 9 7 - and 9 7 5 -(table 1). The palmar interdigital pattern appears most frequently in the third area (table 6).The most common formulae of this pattern are S and -- S but formula -- is not so frequently observed (table 5).Among finger patterns, whorls are very abundant and the percentile is higher than those of any other racial group (table 12).
On the planta of the Oroks, the frequency distribution of the hallucal pattern is a peculiar type compared with those of other peoples, namely the frequencies of the A and B types are somewhat low but the W type is relatively common (table 24).On the plantar interdigital areas, combi-nations of the patterns O O O and O U O are the most frequent (table 26).
In the Giliaks, palmar main line D terminates commonly in position 9, so that the frequency of the main line formula of type 9 becomes much higher than those of other peoples (table 2 and 4).The most common main line formula is 9 7 5 -(table 1).The palmar interdigital pattern appears most frequently in the fourth area (table 6) and the occurrence of formula -- S is strikingly predominant.As in the case of the Oroks, the formula --- is not so frequently observed (table 5).Hypothenar, thenar and first interdigital patterns appear very rarely (table 8 and 9).Among finger patterns, ulnar loops are the most numerous and whorls are rather few for one of the peoples of Eastern Asia (table 12).
