 dilli'riMii'i'S ill the birds of the two lontiiients, — quite enough to establish a dilfeieiiei' of rner, 

 although not of spceific value. The Kuropcaii bird is inueh the darker beneath, the bhukisli- 

 brown spots on juguluin and breast bei:>g blended, or sulVused, .so as to give the predoiiiiiiatiiig 

 tint to this region. 



These ililfereiu'es, thniigh eonstaiit and quite apprei'iable on eoinparisoli, are very slight, while 

 the jiroportioMs are about the same. A young .--lieeiinen of the F.uropeau style dilfeis I'roin Ameri-

 neross the abdomen, iiiiiiiaeuliite white ear-eovevts, eheeks, and throat ; the tibiiu and tarsi are 

 also miioli more thiekly sjiottcd thiin in tlie Aiin rieaii young ; there is also more white on base 

 of outer surfaee of luimaries.
