I secured this pair of birds, male and female, of whose sex 

 I am certain. They were mated and preparing to nest and were 

 in full breeding condition, but are quite unlike in color and meas- 

 urements. These differences tabulated, are as follows : 



It will thus be noticed that the male bird, in the color of its 

 rectrices, partakes strongly of the character of Myiodynastes 

 soUtarius. The bills in this pair of birds differ as much as if 

 they were two distinct species, the male's being long and narrow, 

 that of the female short and broad. 



Megarynchus pitangua pitangua (Linn.) 

 KisKADEE Tyrant. 



Great-billed 



Several seen near Caiio Colorado,

Tyrannus melancholicus satrapa (Cab.), 



THROATED KINGBIRD. 



Lesser White- 



A pair of these flycatchers were seen at the lake of La Brea 

 on April 10th and later several others were observed along the 

 line of the railroad and in the clearing about the huts of the 

 Indians. A loud, strident cry was the only utterance heard. 

 Small flies and beetles formed the principal port of the food. 



These kingbirds were just beginning to build when we left. 

 One nest site was in a tree in front of our house at Guanoco, both 

 birds bringing material and arranging it in the crotch of the 

 branch. 



Family HIRUNDINIDAE. 

 Progne chalybea chalybea (Gmel.). Gray-breasted Martin. 



A pair of these birds alighted on the mast of our sloop at the 

 mouth of the Rio Guarapiche.
