196 skeletons of known age, sex and rac from the Terry Collection were studied in order to document 30 non-metric infracranial traits. Each trait had the ability to be expressed bilaterally, although significant side dimorphism was not observed. Sex differences were statistically significant for some of the traits within a racial group, but these differences were not as pronounced as the differences generated by non-metric cranial traits in the same populations, and were not effective in all racial groups. In general, these infracranial traits show some age dependency when correlation statistics are used, but this dependency is lost when the more robust chi 2 statistic is used. These data suggest that infracranial non-metric traits may be superior to cranial non-metric traits for population comparisons. Infracranial traits may be more durable than cranial traits having regard to the nature of most archaeological material.
为了记录30种非计量性颅下特征，对特里收藏的196具已知年龄、性别和种族的骨骼进行了研究。尽管未观察到明显的双侧二态性，但每个特征都有双侧表达的能力。在一个种族群体中，某些特征的性别差异具有统计学意义，但这些差异不如同一人群中非计量性颅骨特征所产生的差异那么明显，并且并非在所有种族群体中都有效。一般来说，当使用相关性统计时，这些颅下特征显示出一定的年龄依赖性，但当使用更稳健的卡方统计时，这种依赖性就消失了。这些数据表明，在人群比较中，颅下非计量特征可能优于颅骨非计量特征。考虑到大多数考古材料的性质，颅下特征可能比颅骨特征更持久。
