Mammals of the District of Columbia. 101 



In June and July of 1888 Mr. Green shot a large number of bats of this 

 species in Rock Creek valley on the present site of the Zoo. In Dr. Mer- 

 riam's collection are 16 specimens, taken May 14, 1887, under the roof of 

 a barn near the Soldiers' Home, and also a nursing female, shot July 3, 



1888. 



Vesperugo fuscus. Brown Bat. This is the common large bat seen 

 on summer evenings flying about the streets of Washington. It fre 

 quently enters houses through open windows. Specimens have been 

 secured as early as March 8 and as late as December 25. 



Vespertilio lucifugus. This is one of the common bats of the city. 

 Mr. Green and Mr. Richmond have captured large numbers of them in 

 the crevices between the timbers under Long Bridge. In Dr. Merriam's 

 collection are 10 adults and 15 young taken June 16, 1889, and a nursing 

 female taken July 3, 1888. Three specimens in the National Museum 

 were collected in May, June, and August. 



Vespertilio subulatus. Mr. Gerrit S. Miller, Jr., killed one of these 

 bats at Forest Glen, Maryland, only 8 miles from Washington. May 10, 

 1896, and found another dead on May 26, 1896. In the National Museum 

 there is one specimen collected at Alexandria, Va., in August, 1875, by 

 P. L. Jouy. These dates may indicate that the bat is a summer resident, 

 but if the species were not rare more specimens would certainly have 

 found their way into collections. 



Atalapha borealis. Dr. Fisher considers this next to Vesperugo geor- 

 gianus, the commonest bat in the city. Mr. Green reports it as common 

 in the country and in the city streets, and says he has seen it flying about 

 in November. I have examined Washington specimens collected in May, 

 June, September, and November. In the collection of Dr. Merriam 

 there is a female taken June 22, 1889, with two young clinging to her. 



A talapha cinerea. Hoary Bat. A single skin in the National Museum 

 collected at Laurel, Maryland, brings the species within the 20-mile 

 circle. This specimen was taken October 2, 1892, and was probably a 

 migrant. Other records from Baltimore, Maryland, New Jersey, South 

 Carolina, Massachusetts, and Pennsylvania bring the range of the species 

 on all sides of Washington. 



Lasionycteris noctivagans. Dr. Fisher shot one of these bats No 

 vember 12, 1885, between Arlington and Rosslyn, Va. In the National 

 Museum collection are two skins, one labeled Washington. D. C., January, 

 1893, the other Smith Island, Va., September 3, 1893. These dates indi 

 cate that the species is a migrant or winter visitor.
