380 Mr. G. S. Miller, Jr., on the 



species are mentioned, No. 18 of the first edition (here num- 

 bered 2) and the long-eared bat, "F. caudatus, naso oreqae 

 simplicij auricuUs dupNcati's, capite niajon'buft ^^ (pp. 1—2, 

 1761). These had already received binomial names, Vesper- 

 iih'o viun'nus and V. auritus respectively, in the tenth edition 

 of the ' Systema Nature,' where the following diagnosis of 

 V. miirinus is given: '' F. caudatus, naso oreque simplio', 

 miricuh's capite minorihus " (p. 32, 1758). In tlie second 

 edition of the * Fauna Suecica' the teeth of F. murinus are 

 thus described*: — " Dentes primores superiores 6, acuti 

 distantes ; inferiores 4, acuti contigui. Laniarii superiores 2, 

 anteriore majore ; inferiores 3, antico maximo. Molares 

 utrinque 3, tricuspidati." 



It thus appears that the Vespertilio murinus of Linnajus, 

 the type of the genus Vespertilio, is a common Scandinavian 

 bat with ears shorter than the head, and with the dental 



f. 1 -2-2+ 1—1 1—1 3—3 oo 



lormula t ^^^ j, c ^i^, pm ^^121 "* 3113 = 32. 



The only known Scandinavian bats which combine these 

 characters are the members of the group commonly known 

 as Vcsperus in Europe and Adelonycteris in America, but to 

 ■which Mr. Oldfiehl Thomas has recently applied the name 

 Eptesicus^ Rafinesqua|. Therefore the genus Vespertilio 

 Avitli its principal synonymy stands as follows : —
