However that may be, the red bat has been taken far more often in this vicinity. It is not usually found hanging by its thumbs or feet, but rests with its folded wings flat upon some rough supporting .surface, its head being down. In this latitude it is one of the species fre- quenting caverns and hibernating in them. RED BAT. Lasiurus horealis (Miiller). Vespertilio borealis Miill., Natursyst., Suppl., 1776, p. 21. Atalapha noveboracensis of Kennicott and various authors. This species in its various forms is found throughout North America to the arctic regions. The typical form is found in eastern North America from Canada to Florida and Texas and west to Colorado. It is by far the most common bat in this vicinity, or at least the one most commonly taken. The two species of Lasiurus, namely the red bat and the hoary bat, may be distinguished from all the other bats of the state by the fact that the portion of the flying membrane between the hind legs is entirely covered with thick fur on the outside. The red bat is the smaller of the two species. The fore arm is in. (38-43 mm.) in length. The ears (Fig. 10) are very short and rounded for a bat, and the basal lobe has a notch in front which is lacking in the hoary.
