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 % [sustaining membrane] j but the first requires numerous subdivisions. The Bats {Vespertilioy'Lm.)— Have the arms, fore-arms, and fingers excessively elongated, so as to form, ^itli 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 aff"ord attachment to them, as in Birds. The thumb is short, and fur- nished mtli a crooked nail, by which these animals creep and suspend themselves. Their hinder ])arts are [generally] weak, and divided into five toes, nearly always of equal length, and armed with trenchant and sharp nails. They have no coecum to the intestine. Their eyes [except in the frugivorous siieciesj are extremely small, but their ears are often very large, and c
