The system of classification for the higher groups of Passerine 

 birds to be followed in the present work will be that of Professor 

 A. H. Garrod, who, after an exhaustive consideration of many 

 points in their anatomy, has established his classification not on 

 one, but on several characters. I am informed by him that he has 

 devoted great attention to the characters given by Prof. Sundevall 



* Cf. Huxley, P. Z. S. 1867, p. 456.
