When about to spring, this jerboa raises its body by means of the hinder extremities, and supports itself at the same time upon its tail, while the fore-feet are so closely pressed to the breast as to be scarcely visible, which doubtless suggested the name Dipus, or twofooted.
In the young jerboa the proportion of the femur to the rest of the leg is the same as in ordinary running animals.
Among smaller animals the jerboa and other descriptions of rat, and the wabar or cony are common; lizards and snakes are numerous, most of the latter being venomous.
There are two or three varieties of hares, and a species of jerboa and several genera of mongooses.

The ichneumon (Pharaohs rat) is common and often tame; the coney and jerboa are found in the eastern mountains.
Admixture of Mongolian species, such as Canis corsac, Felis manul, Spermophilus dauricus, the jerboa (Dipus jaculus), two hamsters (Cricetus songarus and C. furunculus), three new voles (Arvicolae), the Tolai hare, Ogotona hare (Lagomys ogotona), Aegocerus argali, Antilope gutturosa and Equus hemionus (jighitai).

SETB (Egyptian Set, Stb or StI), by the Greeks called Typhon, was depicted as an animal that has been compared with the jerboa by some, and with t e okapi by others, but which the Egyptians themselves occasionally conceived to be nothing but a sadly drawn ass.
