higher on the eastern side. It is never found outside of the thick, dark 

 forest, keeping near to the ground in the shrubbery and low trees. The 

 nest is always placed in an upright fork of a small shrub, usually from four 

 to six feet above the ground. It is a beautifully built and compact struc- 

 ture. I secured a nest with eggs near Jimenez, May n, 1905. It was 

 situated as stated above, near the edge of a dense piece of jungle, and 

 close beside an old abandoned log-road. It was a cup-shaped structure, 

 made of fine bark fibres, moss, and rootlets, and lined with coarse, black 

 hair-like fibres of one of the common ferns. A tuft of fibres of irregular 

 length trailed from the bottom, and the outer walls were slightly decorated 

 with lichens and spider-webs. The outside diameter was 2.75, the depth 

 2, inside diameter 1.5, depth 1.25 inches. The two fresh eggs were deep 

 cream-color, with some lilac markings and spots of cinnamon in a wreath 

 about the larger end. Measurements: 17X13 and 17. 5X13 mm.

This is one of the rarest of the flycatchers, never having been taken 

 outside of Costa Rica, and probably there are not more than eight or nine 

 specimens of it in existence. Carmiol secured the first specimen at An- 

 gostura, which was recorded by Lawrence under the name of Todirostrum 

 ecaudatum. The next was taken by Gabb in Talamanca, and it was from 

 this skin that the bird was described by Lawrence. It was not taken 

 again until 1889, when Alfaro secured a single bird (?) at Jimenez, August 

 20. In 1 891 and 1892 Underwood secured two birds at the same place, 

 and in 1907 I was fortunate to take three specimens at El Hogar, which 

 is only about three miles from Jimenez.
