CAMPYLORHYNCHUS. 107 
spot of black, becoming a transverse bar on the flanks and crissum. No 
distinct bands on the thigh. Sides of head white except the post-ocular 
stripe, and another along the 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 Ist primary, 1.26, of 2d, 1.90, of longest, 4th (measured from exposed base 
of Ist 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.

Hab. Both coasts of Mexico? On west side north to Mazatlan. 
(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. 
rufinucha, 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, tibie 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 Ist 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, .20. 
This species is readily distinguished from C. capistratus, rufinucha, 
and jocosus, by the reddish head and post-ocular stripe. Its banded 
crissum and the spots on the outer webs of the interior tail feathers
