The throat musculature of Sphenodon is described and figured, and compared with that of lizards. In many features of its throat musculature, Sphenodon may well represent a primitive lepidosaurian pattern, comparable to some extent to the chelonian structure of throat musculature. To infer primitive character states within extant lizards, one cannot simply extrapolate from the condition observed in Sphenodon. In fact, it must be assumed that a rapid change of many features of the throat muscles occurred during the early evolution of lizards in order to provide the basis for further differentiation with extant lacertilian infraorders.
对楔齿蜥的喉部肌肉组织进行了描述和绘图，并与蜥蜴的喉部肌肉组织进行了比较。在其喉部肌肉组织的许多特征方面，楔齿蜥很可能代表了一种原始的鳞龙类模式，在一定程度上可与龟鳖类的喉部肌肉组织结构相媲美。为了推断现存蜥蜴内部的原始特征状态，不能简单地从楔齿蜥中观察到的情况进行推断。事实上，必须假定在蜥蜴早期进化过程中，喉部肌肉的许多特征发生了快速变化，以便为与现存蜥蜴亚目进一步分化提供基础。
