4 The species in question may well be Geochelone pardalis babcocki, the leopard tortoise. There are no tortoises on Socotra today and only two genera in the area of Africa nearest it. Of these one species is the leopard tortoise, which grows to more than two feet in length and so favors mountainous areas that some call it the mountain tortoise. Presumably it existed on Socotra in Roman times. For a full description see Loveridge, A. and Williams, E., Revision of the African Tortoises and Turtles of the Suborder Cryptodira, Bull. Museum of Comp. Zoology, Harvard College cxv. 6 (1957) 235–51Google Scholar. I have handled the shields of a specimen; they are distinctly thicker than those of the hawksbill turtle. I owe thanks to Dr Richard Zweifel of the American Museum of Natural History in New York for much generous help.
