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



' Two specimens, from Costa Rica. 



^ Two specimens in the National Museum 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 Chiriqui (Boquete and Volcan do Chiriqui), 

 kindly submitted to me for examination by 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 ccjlor of the throat. The series exhibits 

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

 exactly as in C. punctulalus, except that the sooty blackish color does not extend over 

 the malar region, and the throat is not yellow. Possible intergradation (op hybrid- 

 ism ?) between C. alhitempora and C. punctulatus is indicated by this series. 



*I have not seen a specimen from any South .American locality, and strongly doubt 

 the subspeciflc identity of the Costa Rican and South American birds. Doubtless 

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

 ceptible of definition.
