From 1861 until 1893 the male and female of this Thamnophilus 

 were each known under separate names, T. bridgesi for the female, 

 and T. punctatus for the male. In 1893 Mr. Cherrie pointed out the 

 error, which is easily seen by anyone studying the birds alive, or 

 examining a large series of properly sexed skins. This bird is found 

 only on the Pacific lowlands and in the foot-hills up to not more than 

 2,000 feet. It is very abundant in the southern part of the country, 

 from Pozo Azul southward, but is found in diminishing numbers as far 

 north as the Volcan de Tenorio (at least) where Mr. Underwood 

 secured a small series in 1908. The birds are usually found in heavy 

 forest, frequenting the undergrowth and low limbs of the trees, and 

 are always seen in pairs or small flocks in company with other ant- 

 thrushes or tanagers. They are very tame and easily approached, 

 seeming to have no fear. They have a rather weak, not unpleasant 

 note, which is usually heard when the bird is unaware of the presence 

 of an intruder. I did not find the nest.
