 Flores, alt. 6000 ft., Chiriqui.) 



Characters. — Brighter, more reddish brown on dorsal surface, in 

 the superciliary line on side of head, and on the flanks; slightly larger 

 than T. s. festinus. 



An adult female, taken on Silla de Cerro Pando, beyond El Volcan, 

 Chiriqui, March 13, 1954, had the maxilla dark neutral gray, except the 

 cutting edge which was marguerite yellow for the basal third, shading 

 anteriorly to mouse brown; basal area of cutting edge in mandible also 

 marguerite yellow; mandibular rami light yellowish, with a line of neu- 

 tral gray at tip and along the side; iris brown; tarsus and toes mouse 

 brown. 



Measurements. — Males (10 from Chiriqui), wing 47.1-49.9 (48.6), 

 tail 28.6-36.2 (29.6), oilmen from base 14.5-16.2 (15.2, average of 9), 

 tarsus 16.5-18.0 (17.4) mm. 



Females (8 from Chiriqui), wing 43.6-48.6 (45.1), tail 27.3-33.1

Resident. Upper levels of Volcan de Chiriqui, 900 to 2500 m, west- 

 ern Chiriqui. 



This small wren, compact and rotund in form, is a forest species, 

 secretive in habit. I found them near and on the ground, in dense 

 tangles, rarely amid fallen tree trunks in small, recently made clearings. 

 Once only, in dense forest, did I see one range 15 m above the ground 

 in a mass of tangled vines near the top of a dead stub. Those seen were 

 silent. 



In the Monniche collection, Blake (Fieldiana: Zool., vol. 36, no. 5, 

 1958, p. 547) recorded a small series taken on the slopes of the volcano 

 above Boquete, between 1580 and 2500 m elevation. 



Griscom described remotus from a single female taken in the moun- 

 tains back of Remedios, Chiriqui. Some form of this species (ochra- 

 ceus group) definitely occurs in the mountains of eastern Chiriqui (Rio 

 Chiriqui, 600-1140 m, near the Fortuna Dam site, where between Feb-
