The ditlereiices between these two varieties are just barely a])i>reciable 

 when specimens of the two, of corresi)onding seasons, are compared. Two 

 Mexican examples (elff/ans) ditl'er more from each other tlian one does 

 from North American specimens ; because one (a typical sj)ecinien received 

 from Salvin) is in the worn, faded, midsummer plumaue, and the other in the 

 perfect autunmal dress. liesides the longer tarsi of these Mexican birds, 

 their tails, and even their bills, are longer than seen in Xorth American skins. 

 IJut while these dill'erences between the Xorth American and ^lexican birds 

 are just apj)reciable, there is one from lirazil (51,017, Sr. Don Fred. Allm- 

 (pier«[ue) wliich is exactly interme^liate between these two varieties in color, 

 while in size it is even smaller than the North American ones, measuring as 

 follows: wing, 1.6(1; tail, !.()(>; culmen, .4.", tarsus, .01. 



Even if recognizable as belonging to different varieties, these specimens 

 are ceHainly all referable to one S2)ecies.
