CAMPYLOEHTNCHUS. 



lot 



spot of black, becoming a transverse bar on the flanks and crissum. No 

 distinct bands on the thigh. Sides of head white except the jjost-ocular 

 stripe, and another along tlie lower edge of the lower jaw. A white line from 

 bill over eye. Bill black, rather paler at the base below ; legs dark-brown. 



Total length, 6.50 ; wing, 3.00 ; tail, 3.00 ; graduation, .41 ; exposed portion 

 of 1st primary, 1.26, of 2d, 1.90, of longest, 4th (measured from exposed base 

 of 1st primary), 2.20; length of bill from forehead, 1.05, from nostril, .69 ; 

 along gape, 1.16 ; tarsus, .94; middle toe and claw, .78 ; claw alone, .21 ; hind 

 toe and claw, .68 ; claw alone, .31. 



This species will be readily distinguished from its black-headed 

 allies by lacking the rufous and unstreaked nape, and by having 

 conspicuous black spots beneath. The bill is longer than in the rest 

 of its allies, and the shape of the nostril is somewhat different.

(29,225.) Top of head and nape light brownish-red, the feathers anteriorly 

 pointed, and with conspicuous black centres. Back light grayish-red, the 

 feathers with rather Irregular black spots in pairs on opposite sides of the 

 webs, with occasional much lighter intervals. The marking much as in C. 

 Tufinuclia, but showing less of the linear streaks, except behind. Markings 

 generally of the wing, tail, and under parts much as in this species. Under 

 parts soiled brownish-white, purer anteriorly, with very obsolete indications 

 of transverse darker bars, and occasional spots on the flanks. Crissum dis- 

 tinctly banded with blackish, tibiae less so. A conspicuous white line from 

 bill over eye along side of head edged above and below with black. A nar- 

 row dusky line from bill to eye, and a reddish-brown one behind it, streaked 

 on its edges with black ; sides of neck streaked with black, and a short black 

 line along lower edge of the lower jaw. Bill dark plumbeous black, paler at 

 the base below. Legs dusky. 



Total length, 6.40 ; wing, 2.75 ; tail, 2.80 ; graduation, ,40 ; exposed portion 

 of 1st primary, 1.06, of 2d, 1.65, of longest, 4th (measured from exposed base 

 of 1st primary), 1.95 ; length of bill from forehead, .80, from nostril, .55 ; along 

 gape, .98 ; tarsus, .94 ; middle toe and claw, .75 ; claw alone, .20 ; hind toe 

 and claw, .66 ; claw alone, .30. 



This species is readily distinguished from G. capistratus, rufinucha, 

 and yocosMS, by the reddish head and post-ocular stripe. Its banded 

 crissum and the spots on the outer webs of the interior tail feathers
