The eggs closely resemble eggs of the Crested Flycatcher of the 

 eastern United States. They are pale creamy buff in color, marked 

 with longitudinal lines, dashes and irregular blotches of bay brown 

 overlying similar markings of purplish drab. They are ovate in form 

 and measure 24.8 x 17; 23.8 x 16.7 and 24 x i"] mm. 



A second nest containing three fresh eggs was found April 12th. 

 This nest was in a hole in the centre of an old rotten stump, about 

 91.5 cm- from the ground, the cavity being open from above. The 

 nesting material was in every way similar to that described above. 

 The eggs are similar in color but with the markings more thickly 

 spread over the surface and consisting of narrower lines, scratches 

 and dashes of color. The measurements are 24 x 17.5; 24.7 x 17.9 and 

 24.2 x 17.7 mm. respectively- 



A male in juvenal plumage, taken at Caicara May 6th, is very 

 similar to the adult, differing only in that the upper parts are more 

 brownish and less olive, and that the wing-coverts and secondaries 

 are broadly edged and tipped with pale russet instead of brownish 

 buff.

 Myiarchiis venezuelensis Lawr., Proc. Acad. Nat. Sci. Phila., 1865. P- 3^- 

 Myiarchus ferox venezuelensis Berlepsch & Hartert, p. 51. 



Much less common than the preceding species. 



Adult birds have the eye seal brown ; bill black ; feet blackish slate. 



I have compared specimens from Ciudad Bolivar and Caicara 

 with Lawrence's type of venezuelensis and find them closely similar.
