A NEW PHAETHORNIS FROM THE SANTA MARTA 
REGION OF COLOMBIA. 
BY OUTRAM BANGS. 
In the latest review of the Trochilida’* Ernst Hartert recog- 
nizes two forms of Phaéthornis longirostris — true P. longirostris, 
ranging from Guatemala to northern Colombia, and P. mexicanus 
of southern Mexico—and regards them as distinct species. He 
places P. cassinii Lawr. and P. panamensis Boucard in the list of 
synonyms of P. /ongirostris. I have just studied with great care 
a large suite of specimens of these hummingbirds and P. sufer- 
ciliosus of South America, which includes the type of P. cassinii ; 
a small series of P. mexicanus, collected by Messrs. Nelson and 
Goldman; topotypes of true 2. /ongirostris from Guatemala; 
specimens of the so-called P. panamensis from Loma del Leon, 
Panama, and Divala, Chiriqui; a large series of skins from the 
Santa Marta region, and examples of various of the representative 
forms, whether species or subspecies, of P. superciliosus. My 
conclusions are much the same as those of Mr. Hartert, except 
that the Santa Marta form, probably unknown to him, must be 
recognized, and that I do not regard P. mexicanus as a distinct 
species; it is an extremely well-marked form, but it appears to 
intergrade directly with true P. /ongtrostris. 
P. cassinti from Turbo is not distinguishable from examples 
from Loma del Leon, Panama, which in their turn are hardly 
different from true P. Jongirostris of Guatemala. The Panama
