198 FORMICARIIDA. 
Mexican State of Vera Cruz. We have no record of it from any point on the western 
side of the Cordillera. 
Mr. Nutting found this bird rather common at Los Sabalos in Nicaragua, where it 
frequented some freshly burnt forest and fed on the insects found there. He did not 
hear its note, but remarked that the iris in life is red 4. .

This race seems to be the prevailing one in Costa Rica and Panama, as all the 
specimens from those countries that we have seen have the white edging to the under 
tail-coverts. The species was first described by Mr. Sclater from a specimen from 
Guayaquil sent to the British Museum by Mr. G. Barclay!. Other examples have 
reached us from Ecuador, and Salmon found it in the Cauca Valley of Colombia®. It 
would thus appear that the bird has a somewhat limited range, extending along the 
countries bordering the Pacific, from Costa Rica to Guayaquil, and doubtless to the 
southern extremity of the forest region of the western side of the Andes of Ecuador. 
Salmon noted the iris in life as red %, in which respect 7. transandeanus agrees with 
T. melanocrissus and with Cymbilanius lineatus.
