GENERAL NOTES. 
PLITSTRELLUS IN MAINE. 
Since so little is known regarding the occurrence of Pipistrellus sub- 
flavus obscurus in the northern portions of its range, the following notes 
from INIaine may be of interest. The only published reference to the 
presence of this bat in the State, which has come to my notice, is that of 
Dr. J. A. Allen in his “ Catalogue of the IVIammals of Alassachusetts.”* 
He writes: “ There are several specimens in the Aluseum of Comparative 
Zoology from Massachusetts, and others from Maine, the latter being at 
present its most northern known locality.” The Maine specimens on 
which this statement Avas based appear to haA^e been lost, and accordingly 
I am unable to cite the locality from Avhich they came. Evidently the 
bat escaped observation again until August 18, 1900, when ]\Ir. A. H. 
Norton of Portland took one in AVindham. He secured tAVO more in the 
neighboring town of Westbrook on September 15, 1908. 
AVitli one exception, the remaining specimens Avhich I have examined 
Avere collected in Winthrop by INIr. A. S. Pope of Manchester on tlie fol¬ 
lowing dates: August 28, 1909, June 1, 1912, July 1, 1913, June 27, 1914 
(contained two large embryos), July 1, 1914. He has supplied me Avith 
a note on their habitat. ‘‘ All my specimens Avere collected in o)ie locality, 
Richard’s Pond, AVinthrop, over tlie water. I haA^e ncA^er taken it around 
the buildings although I Inwe collected ten or a dozen little brown bats 
(Myotis) there.” Air. Norton’s specimens Avere also secured in the 
vicinity of water. 
The localities referred to aboA’e lie in a tongue of the Transition zone 
Avhich enters the soutlnvestern part of the State, and it is here that \A-e 
might expect the northern form of this typically Austral species to reach 
the"limit of its range. It is particularly interesting, therefore, to record 
a specimen from a cave near Allagash Lake in liscatacjuis Co., A\hich is 
in the heart of the Canadian zone in Alaine, and I belicA'e, the most 
northern point from which the species has been taken. It Avas found 
September 9, 1913, in company Avith eleven little brown bats {Myotis 
lucifugus). 
It is safe to conclude that Pipistrellus is common m the Transition area 
of the State, and further search may proA'e it to be a regular inhabitant 
of a portion of the Canadian zone.
