HETERORHINA. : 119 
ous. A white line from bill over the eye along nape; lores, and a stripe back 
of the eye, black; all other feathers of the cheeks, chin, and throat, white, 
narrowly bordered with black. Jugulum dark ashy, middle of breast paler ; 
whole sides of body from and including axillars, the posterior part of belly, 
anal region, and crissum, dark rufous cinnamon. Exposed surface of secon- 
daries and tail feathers rufous, with transverse dark lines; primaries similar, 
externally dentated with black and rufous. Bars on tail much broken up. 
No spots on the coverts ; the alular feathers and bend of wing streaked with 
yellowish-brown. 
Total length of skin, 4.80; wing, 2.35; tail, 1.55; exposed portion of Ist 
primary, .91, of 2d, 1.30; length of bill from forehead, .72, from nostril, .45, 
along gape, .81; tarsus, .98; middle toe and claw, .82; hind toe and claw, .67 ; 
claw alone, .32. 
This species is readily distinguished from H. leucosticta and 
prostheleuca, by its ashy jugulum, want of spots on the coverts, 
and streaked throat. From them and griseicollis it differs in larger 
size, much greater extent of rufous on the sides and anal region, 
darker head, ete. The feathers of chin and throat are edged much 
more conspicuously with black than in HZ griseicollis. 'The outer 
face of the tarsus forms one continuous plate without division or 
groove of any kind. 
I refer this species to the C. leucophrys of Tschudi, although the 
locality of the specimen is much farther north than heretofore given, 
and the bird has not been recorded from Panama. As I have not 
seen a South American specimen, it is possible that a careful com- 
parison may reveal a specific difference.

Of this diminutive species, which differs considerably in appear- 
ance from its allies, the only specimen before me.is somewhat de- 
fective, especially about the bill, so that I am unable to say how 
closely it agrees, if at all, with the other Heterorhine in their peculi- 
arities. The upper parts are of a grayish-brown, rather brighter 
behind ; the wings and tail obscletely marked with transverse dark 
lines. <A line from bill over eye, and urder parts dull white; the
