28 NORTH AMERICAN BATS. 



the genus Scotophilus is described, should have apparently escaped 

 the attention of Continental authors ; to such a degree, indeed, 

 that they credit the genus to Gray as of 1842,' and consequently 

 subsequent to Vesperugo of Keyserliug & Blasius, instead of 

 being long prior to it. I have found no reference in any of the 

 standard European authors to the species Scotophilus kiihlii of 

 Leach, except by Tomes, as in Pr. Zool. Soc, 1861, 35, etc. 

 The following is the arrangement of the species : — 



<i. (Vksperus, Keys. & Blasius.) Central incisors larger than lateral; 

 upper molars 4 ; base of foot with rounded swelling — 



Ears sub-erect ...... S. cnrolinensis. 



Ears turned outwards ..... aS. fuscus. 



b, (Vesperugo, Keys. & Blasius.) Central incisors equal to the lateral; 

 upper molars 5 ; base of foot without rounded swelling — 



Central incisor bicuspid { '^''^S"^ '^^"•^«^' ^^^^^^ ^- ffeorgianus. 



I Tragus thick, obtuse S. noctivagans. 

 Central incisor unicuspid . . . . S. hesperus.
