MAMMALIA. 
few inches of one of these groups, they were not in the least 
troubled by it : their eyes continued closed, and I could perceive 
no signs of respiration. On opening the stomach of one of these 
Bats, it was found entirely empty ; the species, I believe, was the 
V. Noveboracensis." * 
The young of this species continue to nurse till at least a month 
old. 1 shot a female on the 31st of July (1883) whose udders still 
contained milk, and whose long nipples were much drawn out. A 
week later (Aug. 7th), I killed a full grown young flying over the 
same meadow.

Dusky Bat ; Carolina Bat. 
Professor Baird has taken this species at Westport, in Essex 
County, on the eastern border of the Aclirondacks, and I have 
procured a single specimen in Lewis County, on the western side 
of the district ; but it is unquestionably the rarest bat found within 
the limits of this region. It pertains to a more southern fauna. 
In writing of the habits of the Carolina Bat, Dr. A. K. Fisher 
observes : “ They are the last to make their appearance in the 
evening. In fact, when it gets so dark that objects are blended in 
one uncertain mass, and the bat hunter finds that he is unable to 
shoot with any precision, the Carolina Bats make their appearance 
as mere dark shadows flitting here and there while busily engaged 
in catching insects. We have to make a snap shot as they dodge 
in and out from behind the dark tree-tops, and are left in doubt as 
to the result until in the gloom we may perchance see our little 
black and tan, seemingly as interested in the result as we are, 
pointing the dead animal. This species is particularly fond of 
fields well surrounded by trees.” f
