' Four specimens; three from Costa Rica, one from Chiriiiui. 



^ Two specimens, from Costa Rica. 



•^ Two specimens in the National INIuseum collection from Rio Sucio are different 

 from any specimens from other Costa Rican localities with which I have been able 

 to compare them (eleven in number) in their richer coloration, the upper parts being 

 a deeper and more brownish olive-green, and the yellowish olive-green or olive- 

 yellow color of the chest, sides, and flanks more saturated; neither are sexed; both 

 have the tarsus longer than other specimens (22.9-23.4), while one of them (probably 

 a male) has the wing 73.2, which also slightly exceeds the same measurement of any 

 other specimen in the series examined. 



A series of twenty-three adults from C"liiri(|ui ( P>o(|uete and Volcan de Chiriqui), 

 kindl\- su])mitted to me for examination l)y Mr. Outram Bangs, shows that specimens 

 from that district are more brightly colored than those from Costa Rica, the yellow 

 of the chest, especially, being much clearer and, in many specimens, of a slightly 

 orange hue next to the dull whitish or buffy color of the throat. The series exhil)its 

 great, variation in the color of the pileum, some examples having the head colored 

 exactly as in ('. jmiididatus, except that the sooty blackish color does not extend over 

 the malar region, and the throat is not yellow. Possible intergradation (or hylirid- 

 ism ?) between C. alhitonpora antl C punrtiilatvs is indicated l)v this series. 



■'I have not seen a specimen from any South American locality, and strongly doubt 

 the subspecific identity of the Costa Rican and South American birds. Doubtle-ss 

 when a sufficient series has been examined several subspecific forms may be sus- 

 ce])tible of lefinitioii.
