ous. A white line from bill over the eye along nape ; lores, and a stripe back 

 of the eye, black ; all other feathers of tlie cheeks, chin, and throat, white, 

 narrowly bordered with black. Jugulam 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 1st 

 primary, .91, of 2d, 1.30; length of bill from torehead, .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 II. leucosticta and 

 prostheleuca, by its ashy jugulum, want of spots on the coverts, 

 and streaked throat. From them and griifeicollis it differs in larger 

 size, much greater extent of rufous on the sides and anal region, 

 darker head, etc. The feathers of chin and throat are edged much 

 more conspicuously with black than in S. griseicollis. The outer 

 face of the tarsus forms one continuous plate without division or 

 groove of any kind. 



I refer this species to the G. 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 Heterorhinse in their peculi- 

 arities. The upper parts are of a grayish-brown, rather brighter 

 behind ; the wings and tail obsoletely marked with transverse dark 

 lines. A line from bill over eye, and under parts dull white ; the
