 near the middle. Adult: Above, olivaceous-gray, the head darker, 

 approaching sepia-brown, especially on the auriculars ; wings and tail 

 tlai'ker and more brownish than the back, all the feathers faintly edged 

 with i)ale brownish. Malar region, chin, and throat pure white; jugu-

 teriorly; rest of lower j)arts, including lining of wing, clear, rather 

 pale sulphiu'-yellow. Crown with a concealed patch of clear lemon-

 Head pale ash-gray, tinged with light brown, the lores and auriculars

 with olive-green; wing-feathers distinctly bordered with yellowish white 

 (tinged with pale rusty on i\ie coverts) ; tail-feathers edged with pale 

 yellowish fulvous, becoming more rusty around the terminal border of 

 the feathers. Lower i)arts as in the adult, but the abdomen, etc., mixed 

 with patches (new feathers) of bright lemon- or gamboge-yellow. 



Hab. — Mexico, including both coasts ; north to Orizaba and Mazatlau. 



Re^iarks. — This very strongly marked species is decidedly the most 

 robust member of the genus, althougli considerably inferior to T. mag- 

 niro&tris in general bidk. The bill is peculiarly stout, being almost as 

 •leep as it is wide through the base, all its outlines being more decidedly 

 convex than in any other species.
