These fingers are united by a thin mem- brane called the " patagium" (fig. 225, P), which is also ex- tended between the fore and hind limbs and united to the sides of the body. This expanded membrane is used for flight. The pollex and first finger of the fore-limb may have a claw, but the others are destitute of them. The hind-digits have each a long nail.
