104. Myrmotherula fiilviventris Lawr. 



Ouc speciineii shot in the forest oil the E.scoiuUdo, July 2. This Avas 

 the only one observed. It was hopping about in a' tree after tlie manner 

 of a Formieivora. 



105. Myrmotherula melaena (Scl.). 



One shot in the woods on the Rio Prio. It resembled Formieivora 

 in its actions. 

 Feet and claws pale bluish plumbeous, 



106. Cercomacra tyrannina Scl. 



Very common on the Escoudido. One of the Ant Thrushes most 

 frequently seen. Found in bushy places or in low trees in the forest, 

 where it keeps concealed and often utters its chattering note. Almost 

 always found in i)airs, but occasionally noticed roving about with 

 Formicirora and other species. 



107. Formieivora boiicardi Scl. 



Common on the Escoudido. It keeps in the trees some distance from 

 the ground. Sometimes seen in flocks of fifteen or so in company with 

 other species, searching the palm leaves for food, reminding one of a 

 troop of Kinglets or Titmice to some extent. 



108. Ramphocaenus rufiventris (Honap.). 



This curious little bird is rather common at (rreytown, where it passes 

 its time in the bushy thickets. On the Escoudido it is often met with 

 in the forest, hopping about in the thick undergrowth, seldom getting 

 more than a few feet above the ground. It is usually quick and Wren- 

 like in its movements, but at times acts very leisurely, scrutinizing its 

 surroundings in search of ins«ct food, very much after the fashion of a 

 Vireo. It is a quiet, unsuspicious bird, ran-ly uttering a note of any 

 kind, or manifesting uneasiness at the proximity of an unusual object. 



109. Gymnopithya olivascens (Kidj^w.). 



Uncommon on the Escoudido. Apparently confined to the thick 

 undergrowth of the forest, usually found associating with other species 

 of the family, attending the hordes of army ants. Shy and re*;iring. 



Naked skin around eyes pale blue; iris dark crims<m; tarsi, feet, and 

 claws dark plumbecms; upper mandible black. 



110. Gymnocichla chiroleuca Scl. and Salv. 



Quite a common species on the Escoudido, where it frequeuis the 

 undergrowth in the deep woods. Being a shy bird, it is more often 

 heard than seen, keeping well concealed, and flying hurriedly from one 

 clump of bushes to another during its travels in searcli of food. It is 

 doubtless gregarious to some extent, as the birds are generally found
