HYPUROPTILA.—LAMPORNIS. 277 
be distinguished by the rich purple-bronze colour of the upper tail-coverts and tail; the 
tint of the green of the under surface is dark but without blue shade, and the under 
tail-coverts are purple-black instead of white. 
We have no evidence of the existence of any member of this genus in Chiriqui, at 
least not on the Pacific side of the mountain-range. Nor is the genus represented in 
Western Costa Rica.

The purple colour of the greater part of the lateral rectrices in nearly all the species 
of Lampornis, the shorter rounder tail, and normal under tail-coverts serve to distinguish 
this genus from Hypuroptila, which otherwise has structural points in common with it. 
The genus contains ten species, of which four occur within our limits, one of them 
being the very widely ranging L. violicauda, which enters the State of Panama as far 
as the Line of Railway. ‘The most extensively distributed is Z. prevosti, which spreads 
from the middle of the State of Vera Cruz to Costa Rica, a modified form, LZ. hendersoni, 
occupying the island of Old Providence. The fourth species, L. veraguensis, has a very 
restricted range in the western part of the State of Panama.

This well-known and widely-ranging species is only found within our limits at the 
extreme south-eastern portion, 7. ¢. between the line of the Panama Railway and the 
mainland of South America. In the south it ranges over nearly the whole of Tropical 
South America, keeping its specific characters with remarkable precision. Only in the 
birds of Western Ecuador has any separation been attempted of late years, and these 
were described by Gould as L. iridescens, but the differences are hardly appreciable.
