* After a very careful and impartial investigation of the matter, I find myself un- 

 able to coincide with the views of those authors who would identify positively the 

 ffir«»?(ifo^(/»T/ionotoof Vieillot with the H. lunifrons of Say. It is impossible to recon- 

 cile certain discrepancies in Vieillot's descriptiou and those of the authorities upon 

 which his name was based, with the characters of the present bird ; and, even grant- 

 ing that n . jiyrrhonota Vieill. may have been, or even probably was, this bird, there 

 is no more occasion in this instance to "exchange a certainty for an uncertainty" 

 than in other cases which have been objected to. The same applies with equal, but 

 scarcely greater, force to H. americana Gmel. As to the identity of the South 

 American with the North American bird, I have nothing to say, not having seen 

 specimens of the former : but it would be by no moans remarkable if they were the 

 same species. — R. R.
