Edb. Panama, Lion Hill {M'Leamfim^ "). — South America from Colombia^ » 12 to Peru "> 

 Brazil i2j and Guiana. 



This widely-ranging species just enters our fauna as far as the line of the Panama, 

 railway, where M'Leannan found it, and sent specimens to Mr. Lawrence and 

 to ourselves; we have no record of its occurrence elsewhere within the State. In 

 Colombia, Salmon found it breeding near Medellin ^, making a nest of dry stems of grass 

 rather loosely put together in a bush four or five feet from the ground. The eggs are 

 pale greenish white, marked with large blotches of several shades of greenish brown. 

 Mr. Wyatt, too, found it near a stream at Ocana, where it associated in great numbers 

 with S. miwwta, feeding on the seeds of some low bushes ®. 



From Colombia it is universally spread over Tropical America, having been met with 

 by Natterer^, Wallace, Prince Neuwied,' and others, and recently by Whitely in the 

 mountains near Eoraima in British Guiana, at an elevation of 3500 feet above 

 the sea. 



Graf von Berlepsch has separated the Colombian bird from the Brazilian on account 

 of its having a more olive back with less admixture of dark colour. We notice this 

 individual difference, but cannot localize it ; both forms are found in Guiana, and 

 the Panama bird is intermediate. 



S. guttv/ralis has no near allies in the genus, but comes next to 8. luctuosa, from 

 which species it can readily be distinguished.
