Nine adult males from southwest Colombia and the coast of Ecuador 

 south to Puna Island resemble twelve adult males oi D. p. aureola from the 

 Galapagos (loaned by the Nat. Museum), but have the underparts much 

 more broadly streaked. In five specimens these streaks tend to coalesce 

 on the throat which then becomes largely orange-rufous. The most lightly 

 streaked specimen in the series (Bahia de Caraque, Ec.) can be approxi- 

 mately matched by the most heavily streaked specimen in the Galapagos 

 series, showing that although we have a well-marked form in wquatorialis 

 it is not sufficiently differentiated to escape intergradation by individual 

 variation. 



It should be especially noted that north of Tumaco no form of this group 

 has'been recorded from the Pacific coast of Colombia.
