538 Penard, The Genus Buthraupis. [oc t . 



from four to four and one half times the length of the tarsus ; rather pointed, 

 second (from outside) to sixth primaries longer than the first, which is 

 decidedly short but longer than the seventh; third (or fourth) primary 

 longest ; primaries exceeding secondaries by more than or about two thirds 

 the length of the tarsus. Tail from two thirds to three fourths the length 

 of the wing; slightly rounded, the rectrices broad with rounded tips. Tar- 

 sus longer than the middle toe with claw; lateral claws reaching to or 

 slightly beyond base of middle claw. 



The genus, as now restricted, includes the following species 

 and subspecies: 



Buthraupis montana (d'Orbigny and Lafresnaye). 



Buthraupis cucullata cucullata (Jardine). 



Buthraupis cucullata gigas (Bonaparte). 



Buthraupis cucullata saturata Berlepsch and Stolzmann. 



Buthraupis cucullata cyanonota Berlepsch and Stolzmann. 



Cnemathraupis gen. nov. 



Type. — Tanagra eximia Boissonneau. 



Characters. — Bill similar to that of Buthraupis, but shorter; width at 

 base less than depth and about equal to. length of maxilla from nostril; 

 length of maxilla from nostril about equal to or less than one half the dis- 

 tance from angle of mouth to tip; gonys strongly ascending and ridged 

 terminally; nostril less exposed than in Buthraupis. Wing not so long as 

 in Buthraupis, very little more than three and one half times the length 

 of the tarsus; not so pointed, second (from outside) to seventh primaries 

 longest, the first longer than the eighth (or ninth). Tail comparatively 

 longer than in Buthraupis, from three fourths to four fifths the length of the 

 wing. 



The following forms are included in this genus: 



Cnemathraupis eximia eximia (Boissonneau). 

 Cnemathraupis eximia chloronota (Sclater). 



Remarks. — Ridgway (I. c.) has suggested that the ridged condi- 

 tion of the gonys might be of generic importance. This character, 

 however, is found to be rather variable, being more pronounced 

 in some specimens of C. e. chloronota than in others. A specimen 

 of C. e. chloronota in the Museum of Comparative Zoology (M. C. Z.
