73. Loénnberg on Changes in Names. 
[Einige Nomenklaturfragen. Von Prof, Dr, Einar Linnberg. J. f. O. 
1906, p. 528.] 
Although he ‘‘ laments the necessity,’ Dr. Lonnberg 
proposes to change the names of some of our best-known 
species of birds, e. g. clstur palumbarius to Astur gentitis, 
Anas boschas to Anas platyrhyncha, and Muscicapa grisola to 
Muscicapa ficedula, 'The reasons for these and other changes 
advocated by the author are by no means convincing, and we 
do not think that many writers will follow him in adopting 
such proposals.
