Bang ('.-—The southern states north to eentral Indiana. Until 

 recently the species was not supposed to live north of the Ohio 

 River. Prof. L. M. Underwood took two specimens in a cave near 

 Greencastle, Indiana, in December, 1894, but the record published 

 by Butler in the proceedings of the Indiana Academy for that year 

 seems to have been overlooked. Dr. A. M. Banta took a specimen 

 in Upper Spring Cave at Mitchell in 1902, but this was unfortu- 

 nately lost. During the winter of 1906-7 the writer saw six individ- 

 uals in the caves at Mitchell, two of which are now in the collection 

 of Indiana University. In November, 1907, Dr. Charles Zeleny 

 took another individual at the same place. It is apparent, therefore, 

 that the species is firmly established in southern Indiana. 



Habits. — I can find no published account of the habits of this 

 species and my own acquaintance with it is not sufficiently extensive 

 to permit a detailed description. Those that I have seen in the cave 

 were all in dim twilight near the entrance. They hung head down- 

 ward on the side walls of high passages ; in one instance two of them 

 were directly over the water. When sleeping in this position the 

 long ears are curved backward and flattened against the sides of the 

 neck. As far as I know this position of the ears is unique among 

 mammals. The curve is edgewise and the upper or anterior edge of 

 the ear forms a half ellipse. The middle of the posterior edge is 

 formed in a number of small transverse folds. When the animals 

 are awakened from sleep, they slowly straighten the ears, and with 

 them erected, they are truly remarkable looking creatures. 



Two of these bats which were seen on February 22, 1907, in 

 Upper Spring Cave at Mitchell, escaped and flew out into the cold 

 air, perching for a few moments on the rocky ledge at the mouth of 

 the cave. The fact that all that have been seen in this region were 

 near the mouth of the cave, may indicate that the species is not 

 truly a cave dweller. 



The long ears should make it easy to identify in flight if it 

 comes out in the twilight. I have never seen it flying, and judge 

 that it is a later flier. The flight of those that I have had captive, 

 was swift and steady. In captivity, these bats seem to be delicate. 

 Those that I have kept, refused food and soon died.
