THRENETES.—PHAETHORNIS. 317 
Veraguas to Gould, who figured them in his ‘Monograph of the Trochilide.’ The 
bird is now known to be not uncommon in some parts of the State of Panama and also 
in Costa Rica. An allied species of Threnetes from Ecuador was described by Gould as 
Lf. fraseri; this has been united to 7. ruckeri by some writers, but seems to be distinct. 
It has a smaller cinnamon patch on the breast, is greyer on the under surface, and has’ 
darker median rectrices. . 
b!”. Cauda cuneata.

This genus, consisting of about seventeen species, is spread over the lowland forests 
of the greater portion of Tropical America, none of the species ascending the mountains 
to any considerable height. Of the three main sections into which the genus is 
divisible, two only are represented within our limits, each by a single species. 
P. emiliew, which is closely allied to P. guyi, reaches Costa Rica, and P. longirostris 
occurs throughout Central America and in Eastern Mexico as far as the middle of the 
State of Vera Cruz. The section of Phaethornis represented by the latter bird is 
remarkable for the form of the tail, which is cuneate, the central rectrices being 
elongated, and the rest gradually reduced in length towards the outside, and all of 
them conspicuously tipped with white or buff. The bill is long and curved, and no 
glittering marks enter into the coloration of the plumage.
