The purpose of this investigation is to determine relationships between speeds and intermembral lengths and supporting surfaces of 23 species of bats. The indices used were aspect ratio, total loading, wing span, wing area, uropatagial area, length from the wrist to the tip of the wing, and forearm. Generally the more maneuverable bats were found to be smaller, with a lighter loading per unit area, and a larger uropatagial area in comparison to the wing area. The speed, in general, was found to be closely correlated to the overall size of the bat. Determining flight speed by a single index was found to be best accomplished by suing aspect ratio, although single index was found to be infallible in all cases.
