CARNARIA. 67 THE FIRST FAMILY OF CARXARIA,— CHEIROPTERA,— Preserves some affinities with the Quadrumana hy the pendulous penis*, and mamma! which are placed on the breast. Their distinctive character consists in a fold of the skin, which, commencing at the sides of the neck, extends between their four feet and their fingers, sustains them in the air, and even enables such of them to fly as have the hands sufficiently developed for that This disposition required strong clavicles, and large scapulars, to impart the requisite solidity to the shoulder ; but it was incompatible with the rotation of the fore- arm, which would have diminished the force of the stroke necessary for flight. These animals have all four large canines, but the number of their incisors varies. They have long been distributed into two genera, according to the extent of their organs of flight J [sustaining membrane] ; but the first requires numerous subdivisions. The Bats (Vesper tilio, Lin.)— Have the arms, fore-arms, and fingers excessively elongated, so as to form, with the membrane that occupies their intervals, real wings, the surface of which is equally or more extended than in those of Birds. Hence they fly very high, and with great rapidity. Their pectoral muscles have a thickness pro- portioned to the movements which they have to execute, and the sternum possesses a medial ridge to afford attachment to them, as in Birds. The thumb is short, and fur- nished with a crooked nail, by which these animals creep and suspend themselves. Their hinder parts are [generally] weak, and divided into five toes, nearly always of equal length, and armed with trenchant and sharp nails. They have no ccecum to the intestine. Their eyes [except in the frugivorous species] are extremely small, but their ears are often very large, ai*l constitute with t
