BIRDS OP NORTH AND MIDDLE AMERICA. 179 



posterior to the very shallow post-ungual excision; depth of mandi- 

 ble at base decidedly less than width of mandible, about equal to 

 length of gonys; mandible broadly rounded beneath, its tip very 

 slightly if at all produced, very broad; culmen about as long as outer 

 bind toe without claw, gradually and not very strongly dccurved 

 from base, broadly rounded. Wing moderate, very pointed, the 

 longest primaries exceeding secondaries by nearly to quite half the 

 length of wing; ninth or tenth (outermost) primaries longest, the 

 tenth not attenuated at tip. Tail very slightly more than haK to 

 two-thirds as long as wing, graduated for about one-third its length, 

 the rectrices rather broad basally, tapering rapidly to the acuminate 

 or subacuminate tip. Tarsus equal to or slightly longer than outer 

 hind toe without claw. 



Plumage and coloration. — Head completely feathered except a 

 restricted orbital area, cere surrounding nostril, and chin. Color 

 wholly green or green barred and spotted with black. 



Range. — Southern Mexico to Venezuela, Peru, and Bolivia. (Two 

 species.") 



KEY TO THE SPECIES AND SUBSPECIES OF BOLBORHYNCHUS. 



a. Rump and tail-coverts barred or transversely spotted with black; hindneck, etc., 

 narrowly barred with black. {Bolborhynchus lineola.) 

 b. Rump and upper tail-coverts with small terminal spots or bars of black; middle 

 rectrices with much less of black; general color purer, lighter green. (Eastern 



Mexico to Panama.) Bolborhynchus lineola lineola (p. 179). 



bb. Rump and upper tail-coverts heavily spotted with black; middle rectrices 

 with much more of black (sometimes almost wholly black); general color 

 deeper, more olivaceous, green. (Eastern Peru?) 



Bolborhynchus lineola maculatus (extralimital).& 

 aa. No black markings whatever. (Peru; Bolivia.) 



Bolborhynchus andicola (extralimital).c 



BOLBORHYNCHUS LINEOLA LINEOLA (Cassin). 



BARRED PARGQITET. 



Adults (sexes alike). — Above yellowish green (between parrot 

 green and oil green), brighter and purer green on hindneck, passing 

 into clear calliste green on forehead, the feathers of the hindneck 



a B. andicola differs from the type [B. lineola) in the decidedly longer tail, which 

 is two-thirds as long as the wing instead of only a little more than half as long, shorter 

 tenth (outermost) primary, which instead of being longer than the ninth is slightly 

 shorter, and in the relatively slightly longer tarsus; but in other respects they agree 

 very closely and I would not think of separating them generically.
