Hah. Guatemala {Constancia ^% Guatemala city, Antiqua ^, Duenas ^, Quezaltenango 

 and whole Altos of Guatemala to 7000 and 10,000 feet, Coban {0. S. & F. D. G.) ; 

 Costa Eica (Hoffmann^, Frantzius'^^), San Jose (Carmiol^% Irazu {Rogers) ;

 highlands from Colombia ^^ ^'^ and Guiana ^* to the Argentine Eepublic. 



Specimens of this species from all the places mentioned above agree very closely with 

 one another ; the only difference we can trace between examples from Guatemala in the 

 north and the Argentine Eepublic in the south is in the black band of the chest, which 

 in northern examples is continuous, but in southern ones broken into two patches, one 

 on either side of the breast. These two forms seem to be connected by gradual 

 links, and are not specifically separable. 



In Patagonia a closely allied species is found in Z. canicapilla, in which the whole 

 of the crown is grey, the black longitudinal stripes being absent. 



In Guatemala Z. pileata is a very common species in the highlands, and is chiefly 

 seen during the rainy season from May till October. It appears in April, a little before 

 that season sets in, and may be seen about the towns and plantations, the male uttering 

 a short simple song of a few plaintive notes. The nest is built in a low bush, and com- 

 posed outwardly of strong grass stems, roots, and small twigs, and lined with horse- 

 hair. The eggs are of a pale bluish-green ground-colour, spotted or blotched with 

 deep red. 



Dr. von Frantzius also found this bird breeding in his garden in Costa Eica at the 

 commencement of the rains in April ^^. 



In Peru Z. pileata is found tp breed in the mountains during the months of February, 

 March, April, and May ^^. Durnford noticed it breeding abundantly in the neigh- 

 bourhood of Buenos Ayres in October. 



During the dry season in Guatemala, from October to April, less is seen or heard of 

 Z. pileata ; but it was noticed by Salvin near Quezaltenango in the months of January 

 and February 1874. It would therefore appear to be a resident species in Guatemala, 

 or only performing a limited migration between places not far removed.
