specimens from Chicoral, one of which has the chin-tuft more elongate, 

 as in ahditivus. Our material, therefore, indicates that in the eighty-odd 

 miles between Malena and Honda, in which the humid Magdalena Valley 

 merges into the arid Magdalena Valley, ahditivus merges into flaveolus.

Chiromachceris vitellina Hellm., P. Z. S., 1911, p. 1141 (Noanamd; N6vita). 



Inhabits the Tropical Zone of the Pacific coast and, much to my sur- 

 prise, I find that four males from the Cauca Valley agree with this form 

 rather than with M. v. milleri from the lower part of the river. 



I can discover no constant difference between Colombia and Panama 

 specimens but possibly the belly averages paler in specimens from the Canal 

 Zone region, while the orange areas are most deeply colored in a specimen 

 from Chorrera on the southern side of the Isthmus, facts which seem to 

 indicate an approach toward M. aurantiaxius.

Ckiromachmris vitellina Scl. & Salv., P. Z. S., 1879, p. 517 (Remedios). 



Char, subsp. — Similar to M. v. vitellinus (Gould) but male with the throat, 

 breast, sides of the head and nape chrome rather than cadmium, posterior underparts 

 oUve-yellow rather than warbler-green; female paler below, the abdomen, particu- 

 larly centrally, yellower. 



Occupies the Tropical Zone of the lower Cauca in Antioquia, and doubt- 

 less extends eastward to the Magdalena.
