MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 211 



1897. Pipistrellus subflavus Miller, North American Fauna, No. 13, p. 90. 



Type locality. Eastern United States ; probably Georgia. 



Faunal distribution. Austral and lower transition zones ; Atlantic Ocean 

 to Iowa and Texas. 



Distribution in Pa. and N.J. Found abundantly in the lowlands of the 

 southern sections. Declining in numbers northward and there intergrading 

 into the darker race, obscurus, next considered. 



Habits, etc. The flight of this small bat is weak and fluttering, like that of 

 a large butterfly, and the species may be so distinguished at sunset among 

 the other species which then come abroad. 



Description of species. At once known by its small size (smallest of our 

 eastern bats) and yellowish, pale color, undulated by brownish or blackish 

 tipped hairs above. The teeth in this species and genus number 34, disposed 

 as follows : incisors, j^ ; canines, - ; premolars, ^v| ; molars, |-~;j, making 

 1 8 in the lower and 16 in the upper jaw. From obscurus this species is 

 separated by color alone, the northern race being duller, less yellow, and the 

 dark tips of back hairs more conspicuous. The size of both forms is the 

 same. 



Measurements. Total length, 85 mm. (3^ in.); tail vertebrae, 40 (i^-); 

 forearm, 35 (i^4). 



Specimens examined or reported. Pa. Beaver Co., Beaver, 2. Todd, 

 1902, Cumberland Co., Carlisle, 7. Miller, 1897. Delaware Co., Marple, 

 2. Rhoads, 1902. Philadelphia Co., Germantown. Stone. N. J. Cam-

New York Pigmy Bat. Pipistrellus subflavus obscurus Miller. 



1897. Pipistrellus subflavus obscurus Miller. North American Fauna, No. 



i3 P- 93- 



Type locality. Lake George, Warren County, N. York. 



Faunal distribution. Upper transition zone ; Lake George to Ohio ; 

 probably to Minnesota. 



Distribution in Pa. and N.J. The only specimens known from our limits 

 were taken by Mr. Todd in Beaver Co., Pa. He writes me it is " the com- 

 mon form at Beaver." See his notes published in Annals of the Carnegie 

 Museum, vol. i, No. i. The five specimens alluded to were identified by 

 G. S. Miller, Jr. This form is to be looked for in the lowlands of western 

 and northern Pa. 



Habits, description of species, etc. See under P. subflavus preceding.
