 Embemagra torquaia Lafresnaye and D'Orbigny. ) 



Eather large Fringillidfe (total length more than 152 mm.), with 

 rather slender and compressed bill; much rounded wings (ninth pri- 

 mary much shorter than secondaries) ; tail about as long as wing (some- 

 times a little longer or shorter), much rounded; coloration, plain olive- 

 green above (except head and neck), at least sides of head black, the 

 under parts white, with sides and flanks gray or brown, the chest 

 with or without a black coUai . 



Bill rather slender (length much greater than basal depth), much com- 

 pressed, with nearly straight outlines; exposed culmen more than half 

 the length of tarsus; basal depth of bill nearly twice its basal width; 

 culmen strongly ridged, nearly straight to near the tip, where distinctly 

 decurved; gonys about equal to length of maxilla from nostril, gently 

 convex, without distinct basal angle; maxillary tomium with distinct 

 subterm^inal notch, then straight nearly as far as nostril, where inclined 

 slightly upward and then gently deflected to the rictus; mandibular 

 tomium straight to the conspicuously toothed subbasal angle. Nostril 

 small, narrow, obliquely horizontal, the nasal fossae obtusely pointed 

 anteriorly. Eictal bristles long but slender. Wing moderate (about 

 two and three-fourths times as long as the rather long tarsus, much 

 rounded (seventh to fifth primaries longest, ninth shorter than second- 

 aries); primaries exceeding secondaries by less than length of maxilla 

 from nostril. Tail about as long as wing (sometimes a little longer or 

 shorter), much rounded, the feathers broad, with rounded or slightly 

 acuminate tips, less than half overlaid by upper coverts. Tarsus 

 decidedlj' longer than middle toe with claw, its scutella indistinct, 

 sometimes obsolete, on outer side; lateral claws falling decidedly short
