2. _Vespertilio arquatus._--_Head_ large, _ears_ rather shorter than the head, wide, and at tip, rounded, hairy at base, posterior edge with two slight and very obtuse emarginations; the anterior base distant from the eye; _tragus_ arquated, obtuse at tip; interfemoral membrane naked, including the tail to one half of the penultimate joint. Total length 5 inches: tail 1-1/2 inches. Expansion more than 13 inches. This bat might be readily mistaken for the Carolina bat, (V. carolinensis, Geoff.) which it resembles in colour, but differs from it in being of a larger size, the ears broader and proportionally shorter, and an arquated tragus, curving in an almost luniform manner towards the anterior portion of the ear, like that of the V. _serotinus_, Daub. Geoff., though not so broad. The upper incisor teeth, like those of several of our species of bats, are not prominent; they are very much inclined forward, and do not rise at their tips above the level of the intermediate callosity.--JAMES.
