SCOTOPHILUS. 



41 



This species was described by Major Leconte and Dr. Harlan 

 iu the same year ; but the description by the latter gentleman 

 appeared five months subsequent to the former. Vide Cooper, 

 loc. cit. Temminck's account followed the original description 

 five years ; he obtained his specimens from the Prince Max. Wied. 

 I cannot learn upon what ground Major Leconte, in his " Obser- 

 vations," employed Temminck's specific name and discarded his 

 own. It no doubt had, so far as I can judge from given data, 

 the undisputed priority. 



S. noctivagans bears some resemblance to S. discolor, Kuhl, a 

 European species. The shapes of ear and tragus, the color of 

 membranes, the pov^dered fur, and the haired interfemoral mem- 

 brane are common to both ; but in S. noctivagans the color of the 

 hair is blackish instead of brown, and the dentition is different in 

 many particulars. 



No. 5359 is smaller than the other specimens, and has a more 

 subulate tragus. The specimen was imperfect. 



Habitat. — From the Atlantic coast to Rocky Mountains. 



Varies very little in color and size. I have never seen any 

 specimens "entirely black," a peculiarity of coloring stated by 

 Major Leconte to sometimes occur.
