| Abstract: | The “shell mound” Indians exhibit both sexual and bilateral variations in comparative long bone lengths. Mean long bone lengths are shortest in the Indian group when compared to those reported for both Caucasians and Negroes. The radiohumeral and humero-femoral indices of the “shell mound” Indians are higher than those reported for either Caucasians or Negroes. There is a relatively high degree of anterior-posterior curvature of the femur in the Indian group when compared to the femora of Caucasian and Negroes. There is apparently no correlation between maximum femoral length and trochanter length in comparing right and left sides in either sex. The collo-diaphyseal angles are greater on the average on the left side in both sexes. The femora of male “shell mound” Indians exhibits greater average collo-diaphyseal angles than do the femora of male Caucasians. |
