* On examining the type of Schwaneria ceerukafa in the Leyden Museum I 

 found that it was tlie same as Cyoruis ruffrons of Wallace ; arid the supposed 

 generic distinction depends upon the state of the specimen, which lias the 

 feathers worn away from tlie base of the bill. A further comparison shows me 

 that I was wrong ('Ibis,' 1878, p. 41G) in uniting C. rt'fifrons with pale legs to 

 C. beccariana with dark legs, and I have therefore readjusted the svuonymy in 

 the present volume.
