Characters. 
Similar to S. sy/vdordes Lafr. of southern Mexico, but larger; 
rump, wings, tail, under and upper tail coverts, paler rufous; back paler and 
not so uniformly brown, more mixed with grayish olive. From S. amazonus 
Lafr. of the upper Amazon, the new form differs in its very much smaller — 
shorter and weaker — bill and smaller size, though the two are much alike in 
color. 
Color. — Head and under parts grayish olive, slightly washed with reddish 
brown on middle of belly and sides ; back raw umber, with a strong grayish 
olive cast; rump, upper tail coverts and under tail coverts, pale ferruginous ; 
tail rufous chestnut; tertials ferruginous (a little darker and slightly more 
rufous than rump); secondaries similar, but with large central black markings 
and buff-yellow bases of inner webs ; lesser and middle coverts, alula, primary 
coverts and outer edges of primaries, dull olive, slightly more reddish olive on 
outer edges of primaries; rest of primaries dusky, with central buff-yellow 
markings on inner webs, showing as a band on under side of closed wing ; 
under wing coverts dull buff-yellow.

Remarks.— When Mr. Ridgway wrote his synopsis of the genus 
Sittasomus* he was in doubt where to place Veragua specimens, 
putting them under S. sy/vzordes with a question mark. On com- 
paring the good series in the present collection with specimens of 
S. sylvtoides of southern Mexico and with the types of S. amazonus, 
the Chiriqui bird proves to be different from either, though closely 
related to both. From the former it differs in larger size and 
paler color of back, rump, wings, etc., and from the latter in 
smaller size and much weaker bill.
