deeper colored, only the upper part of the throat (sometimes o)dy the chin) unstrcaked, the alxlo- 

 nien usually distinctly spotted ; juf,'ulum deeply tiiit,'ed with lij,'ht brown. Ymtnij nutlc : Similar 

 to the adult femalf, but markinjjs on tin; lower parts all distinctly hurjfitudinal, or .streak-like. 

 Downy iiDUiuj :^ Aliove, dark olivaceous, ri'Iieved by a longitudinal oblong obliciue spot of deep 

 greenish bulf on each side the back (liehind 

 the wings), and a similar spot of clearer yel- 

 lowish on each side of the liase of the tail ; 

 the anterior spots eontluont with the yellow 

 of the sides, the ])osterior ones isdlated by the 

 e.xtension beneath them of the olivaceous of 

 the tail. Pileum and nape similar to the back, 

 but ilarker ; forehead, broad su|>erciliary strii)e, 

 and rest of the head and neck, e.\ce|)t as de- 

 scribed, with entire lower jiarts, deep yellow- 

 ish buff, the side of the head marked with a 

 distinct narrow stripe of dark brown e.vtend- 

 ing from the upper Ikisc of the maxilla to the 

 eye, thence back to the occi]nit. 



Total length (adult), about 15.50-16.50 

 inches ; extent, :i4.0(>-:J4.o(» ; wing, 7.20-7.75 ; 

 culmen, l.Go-1.85; tai^sus, 1.25-1.35 ; middle 

 toe, 1.4t)-1.5(). 



Examples from Chili and Buenos Ayres i-.re larger and more richly colored than those from the 

 Western Unittnl .States ; the white bar acro.s.s the end of the middle coverts narrower, and nearly 

 concealed by the overlying last row of lesser coverts. These differences, however, may not prove 

 constant. 



The female of this species is very ditiiciilt to distinguish from that of Q. discors, and it is prob- 

 ably not possible always to se])arate them with certainty. The present species aveiiiges consid- 

 erably larger, however ; the wing in the adult female ranging from 7.20 to 7..'>0 inches, the cidmen 

 1.70 to 1.75, against G.70 to 7.(M), and 1.40 to 1.50, us in Q. discors. The colors are also deeiMjr,
