nostril to neck ; lores and region below the eye and lower part of cheeks white 

 with slight dusky speck lings ; a stripe behind eye '(between the white cheeks 

 and the superciliary stripe) brown; sides of neck mottled with whitish — the 

 white markings narrowly bordered with dusky; throat, breast and middle of 

 belly while with slight dusky specklings ; flanks and under tail coverts brown 

 (a shade about between raw umber and burnt umber): scapulars brown with 

 longitudinal white shaft spots bordered by dusky; some of the greater coverts, 

 marked in the same way ; wing-; dusky brown, outer edges of primaries white 

 notched with dusky; outer edges of rest of feathers pale burnt umber notched 

 with dusky; bend of wing and lining of wing grayish white: tail dull raw 

 umber, banded and freckled with dusky; legs and feet dark brown: upper

 Young, in nestling plumage, differ from adults in being paler brown above; in

 ish and not so pronounced ; and in having the throat, breast and middle of 

 belly thickly freckled with dusky — each feather having a dusky tip. 



MEASUREMENTS (in millimeters).

Remarks. — Mr. Brown found this peculiar little wren wholly 

 confined to the cane brakes on top of the Volcan de Chiriqui, 

 where it was very hard to shoot, though in considerable numbers. 

 It lived much after the manner of a marsh wren, and its song- and 

 notes were wholly unlike those of any wren Mr. Brown is familiar 

 with. 



In placing the species in the genus Troglodytes, which I do with 

 much hesitation, I may be wrong. Probably, some day. the bird 

 must have a peculiar genus made for it. Troglodytes, as at pres- 

 ent understood, is pretty composite, and it is better to let some 

 one divide it into groups in a thorough manner, than to propose a 

 new genus for this bird now.
