They become quite tame, and show as much intelligence and affection as most wild pets do. HOARY BAT. Lasiurus cinereus (Beauvois). (Obvious mis-. Fig. 11. Head and ear of hoary bat. (Allen.) Vespertilio lincreiis Beauv., Cat. Peale's Mus. Phil , 1796, p. 15. print for cinereus.) Atalapha cinerea of Kennicott and various authors. This species, though apparently seldom abundant in the United States, ranges throughout North America from the Atlantic to the Pacific, north to Athabasca at least, and south through Mexico and Central and South America to Chili. It breeds in Canada and the northern United States, but migrates south in winter. The general shape of this bat is like that of the red bat, but it may be distinguished from that species by characters already des- ignated ; namely, by its larger size (fore arm over 2 in.,or 50 mm., in adults), by the blackish borders of the ears (Fig. 11) and the ab- sence of a notch in their lower lobes, and by the distinct patch of fur near the base of the fore arm. The color varies considerably, but the following description applies to the few Illinois specimens that I have seen: The general color is a mixture of light yellowish brown, deep umber-brown, and white, the yellowish brown being clear and unmixed on throat, head, and under side of membranes, the umber-brown predominating on the back and on the dorsal surface of the interfemoral membrane, where, however, the hairs are mostly tipped with silvery white, some- times to so great an extent as nearly to conceal the dark tints beneath. The lips, chin, and cheeks are sprinkled with short blackish hairs. On the ventral surface white predominates on the belly, between which and the yellow of the throat is a band in which the umber-brown is more conspicuous than elsewhere on the under parts. There are tufts of light yellowish brown fur at the bases
