In southwestern Colombia, at sea-level and upward to 2500 ft., and south- 

 ward in the humid coast region of Ecuador, L. s. squamaecristatus of the Sub- 

 tropical Zone, is represented by a small form which agrees in size with the 

 Costa Rican race. The crest, however, appears to be less developed than 

 in the Bogota form. The differences in color between squamcecristatus and 

 minor are so slight that without reasonably comparable specimens, color 

 characters are not to be depended on. Our Ecuador birds are not taken 

 at the same season as those from Chiriqui and hence satisfactory compari- 

 son of their colors cannot be made. However, as the appended table shows, 

 Ecuador birds resemble Costa Rican ones in size, though in color they do not 

 differ appreciably. It should be noted that no representative of this species 

 has been recorded from the coast region of Colombia north of Barbacoas.
