It measured forty-two and one-quarter inches from the nose to the end of the tail and was a rich mahogany red grizzled with whitish above; the underparts were cream white. As in all flying squirrels, the four legs were connected by a sheet of skin called the "patagium" which is continuous with the body.
A comparison of the hind-limbs of birds with those of bats and pterodactyls suggests strongly that the patagium flyers have arisen from arboreal or climbing animals, while the birds arose from terrestrial forms which acquired the bipedal habit, as certain reptiles have. An arboreal animal would necessarily use all four limbs, as climbing animals actually do.
