﻿NOMENCLATURE. 



17 



georgianus^ of tbe Uuited States. It antedates the name Vesper ugo by 

 exactly ten years. 



Plecotus Geoffroy, 1818^ (Description del'l^gypte, Mammiferes, p. 112), 

 included three species, TOreillard de Danbenton,' 'la barbastelle,' and 

 a new species from Timoi'.'^ 



As no American bats are congeneric with the species originally 

 included in this genus, the name can not be used for any of the genera 

 now under consideration. It has been applied to the si)ecies of Cory- 

 norlilmis. 



Rhogeessa H. Allen, 1866 (Proc. Acad. Nat. Sci. Phila., p. 285), was 

 proposed as a genus to contain the species B. parvula H. Allen and R. 

 tumiila H. Allen. Tlie group, whose validity has not been questioned, 

 has received varying treatment at the hands of different writers. 

 Dobson placed it as a subgenus under ' YeH'perugo,'' but Thomas has 

 recently pointed out its close relationship to Nycticeius. The latter 

 disposition appears to be the more natural. 



The name has been amended to Ehogdesm by IMarscball (Nomenclator 

 Zoologicus, Mamm., p. 11, 1873). 



Scotophilus Leach, 1821 (Trans. Linn. Soc. London, XIII, pt. l,p. 09), 

 type 8. Imhlii Leach, is a genus i^eculiar to tlie Old World, where it 

 apparently replaces the Lasmrus of America. It is mentioned here 

 merely because the name has been used for the North American species 

 of Lasiurus^ VespertiHo^ Lasionycteris^ and ripistrcUns at times wlien 

 these bats were supposed to be congeneric with Old World species. 



Selysius Bonaparte, 1841 (Iconografia Fauna Italica, I, Introduzione 

 [p. 3] ), is a synonym of Myotis Kaup, 1820. It was based on the 

 common European Vesper Ulio mystacinus of Leisler. 



Synotus Keyserling and Blasius, 1839 (Wiegmann's Archiv f. Natur. 

 geschichte, 5ter Jahrgang, Ed. I, pp. 305, 300), was based on the bar- 

 bastelle, a European bat representing a genus not known to occur in 

 America. The name, however, has been applied to the American genus 

 afterwards called Corynorhinns. It is antedated by Barhastella Gray, 

 1821 (London Medical Kepository, XY, p. 309. Type Vesper tilio harhas- 

 tellus Schreber). 



Taphozous Geoffroy, 1818^ (Description de I'lilgypte, Mammiferes, p. 

 113), based on 'Le lerot-volant ' and 'le V. lepftirus,^ which are without 

 rei)resentatives in America. The red bat (Lasiurus horeaUs) was, how- 

 ever, included in this genus by Godman under tlie mime TapJiozoiis rufus?
