Tliis species diners from both M. pniclope and .)/. aincricana in details of form and rolor, which, 

 however, arc merely of sjwciric importance. The bill is (piitn similar, though the commi.ssurc it more ele- 

 vated basnlly and more depressed in the middle, and its greatest width is through the ba.se. The middle 

 tail-feathers are not more elongated than tlie rest, and tlie ujiper tail-coverts are less lanceolate. The color- 

 ation is yet more different, the only similarity lieing in the white wing-covert patch, as in both M. amcri- 

 cana and .V. penelope, and the green space on the side of the occiput, as in the fonucr. The forehead, but 

 also the lores and cliecks, are white. In other respects it differs totally from the two northern si)ecies as 

 follows : Neck black ; jiigubim with liroad transverse bars of black and white ; sides and ilanks plain 

 rufous ; upper tail-coverts iimnaculate white ; speculum jdain opaque black ; crissum rusty. An adult 

 male moasurcs as follows : wing, 10.30 inches ; tail, 4.50 ; culmen, 1.50 ; tarsus, 1.60; middle toe, 1.80 ; 

 width of bill, .70 — the size being thus about the same as that of M. penelope and M. nmericana.
