This species inhabits mainly the lower parts of the Subtropical Zone 

 of all three ranges. I can detect no racial differences in color in our series 

 of seventeen males and fourteen females, but specimens from the Magda- 

 lena region have the tail longer.

Char, subsp. — • Similar to T. a. coronatus Nels., but upperparts, wings and tail 

 darker, the crown between russet and argus-brown instead of cinnamon-brown, 

 and more distinctly defined from the back, the back with a russet tinge, the tail 

 hazel rather than cinnamon-rufous. 



This form, of which we have now two specimens, is clearly an inter- 

 mediate between T. mquatorialis of eastern Ecuador and southeastern 

 Colombia, and the quite different T. anabatinus group of Panama to 

 Mexico. Being forms of the Tropical Zone the ranges of wqiiatorialis and 

 intermedius are apparently separated by the Andean system, but the near 

 relationships of oequatorialis and anabatinus are indicated by the discovery 

 of this Colombian race. The specimen from Alto Bonito agrees with the 

 type.

An adult male and female collected by Miller and Boyle at Puerto 

 Valdivia, are, so far as I am aware, the first specimens of this rare species 

 to be taken by other than native collectors. The male agrees with the type, 

 due allowance being made for the somewhat faded condition of the latter, 



Puerto Valdivia, 2.
