The parachute is supported by a cartilage attached to the wrist or carpus; in addition to the lateral membrane, there is a narrow one from the cheek along the front of each shoulder to the wrist, and in the larger species a third (interfemoral) connecting the hind-limbs with the base of the long tail.
The needs for these are obvious - buoyancy in water and resistance to wetting for the first, some form of parachute for the second, and some attaching mechanism or attractive structure for the third.
The Indian flying-squirrel (P. oral) leaps with its parachute extended from the higher branches of a tree, and descends first directly and then more and more obliquely, until the flight, gradually becoming slower, assumes a horizontal direction, and finally terminates in an ascent to the branch or trunk of the tree to which it was directed.
The top of the buggy caught the air like a parachute or an umbrella filled with wind, and held them back so that they floated downward with a gentle motion that was not so very disagreeable to bear.
The species without a parachute constitutes the genus Zenkerella, and looks very like an ordinary squirrel (see Rodentia).
Since, however, this parachute is absent in some members of the family, the most distinctive character is the presence of a double row of spiny scales on the under surface of the tail, which apparently aid in climbing.
The helicopter righted itself fast, and she saw the parachute Brady had been trying to release by smashing his fist against the control box in the ceiling.
To this family also belong the Rhacophorus of eastern Asia, arboreal frogs, some of which are remarkable for the extremely developed webs between the fingers and toes, which are believed to act as a parachute when the frog leaps from the branches of trees (flying-frog of A.
