Abstract
DURING a comparative study of the osteology of some Egyptian geckos, including Stenodactylus stenodactylus, Tropiocolotes tripolitanus, T. steudneri, Ptyodactylus hasselquistii, Hemidactylus turcica, Tarentola mauritanica and T. annularis, a rather interesting detail concerning the caudal region of the vertebral column was observed, which has not previously been recorded in living Lacertilia, so far as we are aware. It concerns the presence of caudal ribs in geckos. Among the above-mentioned species, such ribs were found in both Tarentola annularis and Ptyodactylus hasselquistii.
