T. zeledoni the general colour above is of an olive-brown cast or ashy, 

 with a decided absence of rufons or fawn-colonr, the whole undcr- 

 parts being white, with the flanks and under tail-coverts only ful- 

 vescent brown ; there is a decided shade of ashy on the sides of the 

 breast, and the checks are ashy white, streaked with dnsky. 



T. leucotis is scarcely more than a race of T. modestus, with the 

 fawn-colonr of the iinderparts extending up to the throat, which 

 is buffy white ; the bands on the wings and tail are much broader. 

 T. superciliaris is yet another race, with a very much longer bill and 

 the sides of face and underparts white. 



The Central- American Wren inhabits Guatemala and Costa Eica, 

 from 1000 to 6000 feet elevation.
