Abstract
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.
期刊介绍:
African Journal of Herpetology (AJH) serves as an outlet for original research on the biology of African amphibians and reptiles. AJH is an interdisciplinary journal that publishes original articles and reviews from diverse fields and disciplines, such as conservation, phylogenetics, evolution, systematics, performance, physiology, ecology, behavioural ecology, ethology, and morphology.
The Journal publishes two issues a year. There are no page charges .
