^ I have thought it needless to occupy space by adding the name of the Families, 

 which in nearly every case will be readily supplied, though where there is more than 

 one referred to any higher division, I have inserted the number. The Family-names 

 are given by Mr. A. H. Evans (Zool. Rec. xzii. Aves, pp. 14-18), by Dr. Sharpe 

 {Attempts to classify Birds, pp. 24-29) and Dr. Gadow {ut suprd, pp. 46-48).
