Subgenus NYCTHERODIUS Eeichenbach, page 133. 



The name Nyctherodius, as applied by Eeichenbach (in 1852) to this subgenus 

 (or genus), being antedated by its use in an entirely different connection by Mac- 

 gillivray in 1842, Dr. Stejneger has proposed (Proc. U. S. Nat. Mus. x. 1887, in 

 press) as a substitute the name Nyctanassa, with Ardea violacea Linn, as type. 



No. 198. Ardea rufa Bodd., page 131. Reddish Egret. 



This name being preoccupied (by Seopoli, in 1769) for another species, it 

 becomes necessary to substitute the next in order of date. The species will there- 

 fore have to be called Ardea rufescens Gmel. (S. N. i. pt. ii. 1788, 628). 



Genus SYMPHEMIA Eaeinesque, page 167. 



Mr. Brewster has recently separated the western birds of this species as a 

 geographical race, the main distinctive characters of which are as follows : —

 color of upper parts darker, more olive-grayish, more heavily spotted or 

 barred with dusky, the anterior and lateral lower parts also more heavily

 men 2.02-2.31 (2.19), tarsus 2.08-2.42 (2.29). Hab, Atlantic coast of United

a 2 . Larger, with relatively longer and slenderer bill ; summer adults with ground- 

 color of upper parts paler, more ashy, gray, less heavily marked with dusky,
