Palmer's series as well as several examples from Western 

 Ecuador difler at a glance from true M. o. oUvaceus, of Costa Rica 

 and Chiriqui, in having the back much duller, less yellowish 

 green, the pileum more greyish green, and the olive streaks on 

 the anterior under parts much darker and more strongly marked. 

 The Colombian and Venezuelan races, M. o. galbinus Bangs *" and 

 31. 0. venezuelensis Ridgw.f, are much brighter green above, the 

 pileum being scarcely darker than the back, and the general colour 

 of the lower surface is much deeper yellow, with the dark streaks 

 more decidedly green. 



M. 0. hederaceus replaces the typical form in the lowlands and 

 on the Pacific slopes of the Western Cordillera of Colombia and 

 Ecuador. 



Whether its ally M. striaUcolUs D'Orb. & Lafr. also occurs 

 in Western Colombia % I am unable to ascertain, but it should be 

 mentioned that the numerous skins I have examined from 

 Western Ecuador were all referable to M. o. hederaceus.
