1917.] Chapman, Distribution of Bird-life in Colombia. 471 



A common inhabitant of arid, semi-arid or cleared and bush-grown 

 places in the Tropical Zone, throughout the greater part of Colombia. We 

 have taken it at Tumaco but at no other point on the Pacific coast, Caldas, 

 being faunally a part of the Cauca Valley rather than of the coast region. 

 Topotypical (Lima) specimens of heterurus are larger, and the female ap- 

 pears to be more richly colored than specimens from Ecuador and western 

 Colombia, but I have not sufficient Peruvian material to reach satisfactory 

 conclusions in this connection. 



Although this Flycatcher doubtless occurs at Villavicencio we did not 

 secure specimens, and I am unable therefore to state whether birds from 

 that part of Colombia show any approach to the well-marked P. r. saturatus 

 of Orinocan Venezuela.

The receipt of additional specimens of this bird from a locality far re- 

 moved from that whence I had described "Knipolegus columbianus" , in- 

 duced the belief that, although the type of that " species " had been examined 

 by and was unknown to most of the leading ornithologists of this country, 

 it represented a species which had been previously described. Specimens 

 were therefore submitted to Count von Berlepsch who revealed its true 

 identity. 



I still fail, however, to appreciate the bird's relationships to typical 

 members of the genus Empidochanes and as before suggested (I. c.) feel 

 that it deserves generic separation. This species evidently occurs in the 

 Subtropical Zone of all three ranges.
