208 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 



Type locality. Georgia. PNear Riceboro, Liberty Co. 



Faunal distribution. North America north of Mexico, except in the 

 Rocky Mountains and Pacific coast south of southern Alaska ; viz. inhabit- 

 ing the Arctic, Hudsonian, Canadian, transition and austral life zones. 



Distribution in Pa. and N.J. While this bat is to be found throughout 

 our limits, it is apparently more numerous in the transition and Canadian life 

 zones than in the austral. 



Description of species. Color dull, glossy brown above ; beneath, on belly, 

 paler, more yellowish ; ears and wings light brown. Size small ; teeth differ- 

 ing from those of the next species (subulatus) in the form of the third lower 

 premolar. " When viewed from the side this tooth is conspicuously broader 

 in proportion to its height in M. subulatus. When viewed from above the 

 tooth is much larger in M. subulatus and distinctly longer than broad, while 

 in M. lucifugus it is nearly as broad as long." These two species may be 

 genetically separated from other species in our limits by the following tooth 

 formula : Incisors, ". -^ ; canines, ~ J ; premolars, -^| ; molars, ~|, equal- 

 ing 38 teeth in all, 20 in the lower -jaw and 18 in the upper jaw. The back 

 of the membrane between the legs is naked in this genus except at the 

 extreme base. In lucifugus the ear laid forward barely reaches the end of 

 the nose, in subulatus the ear reaches considerably beyond the nose. They 

 do not differ appreciably in color nor in size. 



Measurements. (lucifugus} Total length, 85 mm. (3^ in.); tail vertebrae, 

 38 (i#); forearm, 38 (i^): (subulatus) 85 ( 3 #) ; 38 (t%); 35 (i#). 



Specimens examined or recorded. Pa., from Beaver, Butler, Cambria, 

 Clarion, Clinton, Elk, Erie, McKean and Westmoreland Cos. N. J. from 

 Camden and Warren Cos. 



Say's Little Brown Bat. Myotis subulatus (Say). 



1823. V.\_espertilio~\ subulatus Say, Long's Expedition, Rocky Mountains, 



VOl. 2, p. 65. 



1897. Myotis subulatus Miller, North American Fauna, No. 13, p. 75. 



Type locality. Arkansas River, near La Junta, Otero county, Colorado. 



Faunal distribution. North America ; east of the Rocky Mountains ; 

 north of the Arctic zone. 



Distribution in Pa. and N. J. Occurring, or likely to occur, in all locali- 

 ties. 



Habits, etc. The habits of both species of small brown bat found in Pa. and 

 N. J,, so far as they are disentangled, seem to be similar. Dr. H. Allen says 

 they are a strictly " pastoral " as contrasted with the " urbal " kinds which 

 infect houses and and outbuildings. They seem to congregate in caves and 

 hollow trees, or under the bark of decayed tree trunks. Mr. Todd found
