Abstract Vestigial appendicular skeletons are present but have not previously been described and illustrated in the skink species Feylinia grandisquamis and Melanoseps ater. Vestigial appendicular skeletons have been described and illustrated in only one specimen of Grandidierina lineata and in a small sample of Voeltzkowia mira. Here we report a radiographic study of the appendicular skeletons of these four species. The pectoral girdle includes a vestigial clavicle in F. grandisquamis; a vestigial scapulocoracoid and sternum in M. ater; a vestigial scapulocoracoid, interclavicle and sternum, with or without a clavicle, in G. lineata; and a clavicle and scapulocoracoid in one specimen of V. mira. In all four species the pelvic girdle includes an ilium and a puboischium. No midline contact is present between the left and right puboischium, and visible forking into a distinct pubis and ischium is present only in V. mira. The only discernible limb vestiges are humeri in V. mira.

非洲和马达加斯加石龙子物种 Feylinia grandisquamis、Melanoseps ate、Grandidierina lineata 和 Voeltzkowia mira 中的残余附肢骨骼

摘要 残留的附肢骨骼存在，但以前没有在石龙子物种 Feylinia grandisquamis 和 Melanoseps ater 中得到描述和说明。仅在 Grandidierina lineata 的一个标本和 Voeltzkowia mira 的一个小样本中描述和说明了残留的附肢骨骼。在这里，我们报告了对这四个物种的附肢骨骼的放射学研究。胸带包括 F. grandisquamis 的一个残留锁骨；M. ate 中的一个退化的肩胛骨和胸骨；G. lineata 中残留的肩胛骨、锁骨间和胸骨，有或没有锁骨；以及一个 V. Mira 标本中的锁骨和肩胛骨。在所有四个物种中，骨盆带包括髂骨和耻骨。左右耻骨之间不存在中线接触，可见分叉成明显的耻骨和坐骨仅在 V. mira 中存在。唯一可辨别的肢体痕迹是 V. mira 中的肱骨。
