Hab. NicAEAGUA, Chontales {Belt '') ; Costa Eica ^ (Hoffmann, v. Frantzius), Angostura, 

 Guaitil [Carmiol ^ \ v. Frantzius ^ *), San Juan [v. Frantzius *). 



This Costan-Rican species was discovered by Hoffmann and v. Frantzius, and though 

 an allied Guatemalan bird has since been referred to it, further comparison has shown 

 that the more northern species is really distinct, as will appear below. Thus Pyrgisoma 

 leucote has a very restricted range, which hardly extends beyond Costa Rica, though 

 Belt found it in the Chontales district of Nicaragua. 



Its habits have not been described, but they doubtless resemble those of the allied 

 bird P. occipitale, of which we give a short account below.

A good deal of uncertainty for a long time prevailed respecting this Guatemalan 

 species. The first specimen obtained (a young one) was referred to Chamceospiza 

 torquata. It was then placed with the Costa-Rican P. leucote, under which title it 

 was figured in ' Exotic Ornithology,' and it was not until 1878 that Salvin finally sepa- 

 rated it under the name of P. occipitale. 



We only know of the occurrence of this Finch in a very limited district of Guatemala, 

 as all our specimens have befen obtained from the second-growth forests lying between 

 the volcanoes of Agua and Fuego at altitudes ranging between 2500 and 5000 feet 

 above the sea-level. Here it is usually seen on or near the ground, scratching amongst 

 dead leaves with its strong feet.

This genus was founded by Wagler to contain A. pileatus, the only species properly 

 belonging to it, though several others have been temporarily placed in it by various
