N0.125.S. COLLECTION OF HUMMINGBIRDS— OBERHOLSER. 313 
There are apparently" five recognizable races of this species, namely: 
Phoethorni^Iongirostris longirostris (Delattre). — Guatemala to Colombia. 
Plioethornitt longirostris mexicnnus (Hartert). — Southern INIexico. 
rhoethornis longirostris susur^'us Bangs. — Santa Marta, Colombia. 
Phoeihornis longirostris baroni (Hartert). — Western Ecuador. 
PhoetJiornis longirostris boliridnus (Got'Ln). — Bolivia and Peru. 
PHOETHORNIS HISPIDUS (Gould). 
TrocMlus ( ?) hispid us Gould, Proc. Zool. Soc. Lond., 1846, p. 90. 
Phaetornis liispidus Bonaparte, Consp. Avium, I, 1850, p. 68. 
The one adult male from Archidona, east Ecuador, apparently does 
not differ materially from Colombian specimens. 
All the specimens we procured of these three species {PlmetJiornis yaruqiii, P. lon- 
girostris, and P. hispidus) were shot in the gloomier parts of the forests among the 
undergrowth, and all had the same peculiar way of hovering at times in front of 
one's face or close to the barrel of the gun, a peculiarity which I never once observed 
in any of the hummingbirds found out in the open. P. hnigirostris and P. yanupd 
are confined solely to the western forests, and P. hispid its to the eastern side. 
PHOETHORNIS SYRMATOPHORUS BERLEPSCHI (Hartert). 
Phaethornis berlepschi Hartert, Nov. Zool., I, 1894, p. 56. 
A single example from Milligalli, west Ecuador, seems to be typical 
of herlepsch!, which evidenth^ represents true syrmatoj^horus on the 
west side of the Andes. Apparenth" typical specimens of herlepschi 
from Quito are in the collection of the National Museum. 
The single specimen was shot whilst hovering over a bush on the river l>ank. 1 
was told that these birds used to be very plentiful in this locality, but of recent years 
they have almost entirely disappeared. 
PHOETHORNIS GRISEOGULARIS Gould. 
Phaethornis griseogularis Govi.T>, Proc. Zool. Soc. Lond., 1851, p. 115. 
Three specimens, from Archidona, east Ecuador. While the best 
character separating this species from I*, drilgularis seems to be 
the color of the tail, yet the deep, almost uniform rufous of the lower 
surface will almost, if not quite, alwaj^s serve to distinguish the 
present l)ird. 
Confined to the eastern forests, and we did not once see them in the open. They 
have nuich the habits of Phoethornis. 
PHOETHORNIS STRIIGULARIS ATRIMENTALIS (Lawrence). 
PJiuethomis dtrimentalis Lawrence, Ann. N. Y. Lye. Nat. Hist., VI, 1858, p. 260. 
Two specimens, from Milligalli, west Ecuador. These differ from 
Colom])ian birds in being brighter, more rufescent below, and in 
having the chin together with the upper throat less conspicuously 
streaked with dusky. These differences appear to be sufficient for the 
recognition of the Ecuador l^ird as a geographical race. The type of
