At one time it was thought that Baird’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 “ Cenlronyx,” had appeared. Mr. 
Maynard made the correction in 1872, when the New England bird 
was named Passerculus princeps. 
The complete synonymy of the ta species, and tear nearly en- 
tire bibliography, are as follows : — 
Passerculus princeps.

being to P. princeps). — Matn., Am. Nat. iii, 1869, 554 (next notice of 
the same). — Allen, Am. Nat. iii, 1869, 631 (third notice of the same).
