only two, and I could not positively identify 

 them, but they were probably red bats. 



August 25, 1890. An adult male taken. 



August 28, 1890. Two seen. 



August 29, 1890. The evening was too 

 chilly for many bats to be on the wing. A 

 few A. noveboracensis seen and two taken. 



August 30, 1890. Six or eight A. novebora- 

 censis seen and three taken. The evening 

 was warm and bats flew much more freely 

 than on the 29th. 



August 31, 1890. A chilly evening again, 

 and only two bats seen, both A. noveboracen- 

 sis. 



September 2, 1890. A few red bats seen 

 and two taken. 



September 5, 1890. I was not at Highland 

 Light this evening, but Mr. W. M. Small re- 

 ported a heavy flight of bats. He shot five, 

 all A. noveboracensis. 



September 8, 1890. Heavy fog, so that no 

 bats could be seen, if any were moving along 

 the face of the bluff. Three or four red 

 bats flew about the light house tower dur- 

 ing the first half of the night, feeding 

 on insects attracted by the light. They 

 flew mostly below the level of the deck 

 which encircles the tower about six feet be- 

 low the lantern and never approached the 

 light itself. 



September 12, 1890. A single red bat shot 

 this evening. 



After this date I watched for bats on sev- 

 eral consecutive evenings. As I saw no 

 more I concluded that the migration had 

 ended. 



August 25, 1891. Fourteen Atalapha nove- 

 boracensis, the first bats of the season, seen 

 this evening. They were flying both north 

 and south. 



August 26, 1891. Evening very foggy. A 

 red bat which flew about the lighthouse 

 was the only one seen. 



Harrison Allen in his latest Monograph of the Bats 

 of North America (1893), although many of these 

 will require revision. 



August 27, 1891. Half a dozen red bats 

 seen and one taken. 



August 28, 1891. Four red bats seen. All 

 flew toward the south. 



August 30, 1891. A red bat caught in a 

 house near the edge of the bluff. 



September 2, 1891. Eight or ten seen and 

 three taken. The movement this evening 

 was mostly, though not wholly, from north 

 to south. 



Sepitember 3, 1891. Six seen and three 

 taken. 



September 5, 1891. Evening cold and 

 misty. No bats moving. 



September 7 and 8, 1891. A few bats seen 

 each evening, but none taken. All ap- 

 peared to be this species. 



September 10, 1891. One red bat shot. 



September 11, 1891. One seen. 



September 12, 1891. One killed. About a 

 dozen bats seen, but how many were of this- 

 species, and how many Lasionycteris noctiva- 

 gans I could not determine. 



September IS, 1891. About a dozen bats 

 seen. Two of these were certainly red bats. 



After this date I watched for bats on con- 

 secutive evenings for more than a week. As 

 I saw none I finally gave up the search. 



ATALAPHA CINEEEA (HOAEYBAT). 



August 26, 1890. One Atalapha cinerea,. 

 the only bat seen, shot this evening. 



August 28, 1890. Two hoary bats taken ^ 

 and at least two, and probably four, others 

 seen. 



August 30, 1890. Two taken and two 

 others seen. 



September 2, 1890. Only two seen. Both 

 taken. 



No more hoary bats seen during 1890. 



August 25, 1891. A single Atalapha cinerea, 

 seen flying south along the face of the bluff 

 this evening. 



September 2, 1891. One seen flying north. 



September 12, 1891. An adult male shot — 

 the last of the season.
