2 Coues on Passerculus bairdi. 



There is no occasion here to enter into its history, as all that is 

 known is already published in the works below cited, — the more 

 complete notices being those in the "Birds of the Northwest" and 

 the " History of North American Birds," especially in the Appendix 

 of Vol. III. of the latter. 



At one time it was thought that Baud's Bunting had been found 

 in Massachusetts. The error was not rectified until several notices 

 to such effect, including Mr. Maynard's full account, and his plate 

 of the supposed Massachusetts "Centronyx" had appeared. Mr. 

 Maynard made the correction in 1872, when the New England bird 

 was named Passerculus princeps. 



The complete synonymy of the two species, and their nearly en- 

 tire bibliography, are as follows : ■ — ■
