Costa liica. Leaving out young specimens, T have examined a 

 considerable number from this country, which show no differences 

 from Uuatemalan examples. It was from Costa liica that Cabanis 

 described his Trofjlodijtes intermedhts.

The Ruddy-sided House-Wren inhabits Central America, from 

 the state of Oaxaca in Mexico and Yucatan to Costa liica and Gua-

 of elevation.

Though very closely resembling T. intermedins of Costa Eica and 

 Guatemala, we are struck at once by a difference which the Panama 

 birds cxhiljit on their flanks, these being perceptibly barred ; the 

 back and mantle also appear more banded than in true T. inter- 

 medins. Not much difference in size is exhibited, and the propor- 

 tions of the first and second primary are as in T. domesticus. The 

 following measurements are taken from the series in the British 

 Museum and in the collection of Messrs. Salvin and Godman : —
