52 VESPERTILIONID^— NYCTALUS 



made to include any of the Linnaean species. Lilljeborg (Sveriges 

 och Norges Ryggradsdjur, i., 124-126, 144, 1874) followed 

 Blasius, insisting that it is impossible to determine whether 

 Linnseus's bat is the species afterwards called Vespertilio 

 discolor by Natterer, or that called Vespertilio nilssoni by 

 Keyserling and Blasius, but, contrary to the opinion of Nilsson, 

 he favoured the latter. Lilljeborg, although aware of Blasius's 

 mistake in applying the generic name Vespertilio to a group 

 containing no species known to Linnaeus, concluded that as the 

 error had become time-honoured, it were better uncorrected. 



Mr Miller concludes that, " Notwithstanding the incon- 

 venience to which such a course leads, there can scarcely be 

 any valid reason for rejecting the identification of Linnseus's 

 Vespertilio murinus made by Nilsson. The doubt admittedly 

 lies between two species, one of which he deliberately chose with 

 all the facts before him. As nothing in the original description 

 is in any way discrepant with this determination, it should be 

 adopted."

Classification and Synonymy: — Mr Miller has shown that 

 the genus Vesperugo of Keyserling and Blasius, as originally 

 defined, is inadmissible. It included twelve species : serotinus, 

 discolor, nilssoni, savii, leucippe, aristippe, noctula, leisleri, 

 kuhlii, albolimbatus, nathusii, and pipistrellus. These were
