After considerable hesitation, Salvin described this species in the ‘ Catalogue of Birds 
in the British Museum’ 8, having previously noted some of the differences which distin- 
guish it from P. amabilis }. | 
This form seems to be strictly confined to the district of Chiriqui, and is probably 
found there only on the Pacific side of the mountains. | | 
e". Cauda requlariter rotundata, rectricibus latis aut aureo-cupreis micantibus, 
aut chalybeis aut castaners. 
e"". Cauda lete aureo-cuprea ; stria elongata postoculari nulla. 
CHRYSURONIA. 
Chrysuronia, Bonaparte, Consp. Av. i. p. 75; Salv. Cat. Birds Brit. Mus. xvi. p. 248. 
In Chrysuronia the tail is rounded, the feathers being broad, and in this respect it 
resembles the next genus, Basilinna; but in all the members of Chrysuronia the tail is 
of bright glittering colour; moreover, there is no long postocular white stripe, which 1s 
a very marked feature in Lastlinna. 
The number of species in Chrysuronia is five, which are distributed over nearly the 
whole of Tropical America as far south as the Argentine Republic; no species, however, 
occurs in Eastern Brazil. In Central America one species, C. elicie, is found, which is 
peculiar to that country.
