' The species of Trogon reterred to by Mr. W. E. D. Scott iu the Auk for Octo- 

 ber, 188(j, p. 425, is without much doubt the ouly other Mexicau species of typiciil 

 Trogon with red breast (T. elcgans Gould, T. mcxicanus Sw., and T. puella Gould), 

 being confined to the southern portions of that country. A yellow-breasted species 

 (T. dtrcolus Gould) is common in the vicinity of Mazatlau, and may possibly occur 

 as far north as Southern Arizona.
