The present species is a western race of our common wood pewee, {C. 

 virens,) which it is scarcely distinguishable from except on comparison. 

 The most appreciable difference is seen in the breast, which in Richard-

This western race of E. trailUi was very common in the Salt Lake 

 Valley, where I collected seven specimens and three nests. They build 

 a neat, compact little nest, which they place in the fork of a rose or
