Four specimens, from Santo Domingo, west Ecuador. The female 
of this species is somewhat smaller than the male, though apparently 
almost identical in color. xVccording to the collector's notes upon the 
labels of these examples the mandible in both sexes is c7'rmso7i in life. 
PHOETHORNIS LONGIROSTRIS BARONI (Hartert). 
PJiai'thornif! huroirl Hartkrt, Ibis, 1897, p. 426. 
A single specimen from Santo Domingo, west Ecuador, belongs 
apparently to this form. It is similar to Phoeihornis. longirodvh Jon- 
(jiroi<trh., but nuich smaller; the upper surface is green, with ver}' much 
less of l>ronzy tinge; the ochraceous of rump and upper tail-coverts 
much paler; the lower parts much less ochraceous, the crissum almost 
white; the tips of rectrices grayish white instead of ochraceous. It 
may l>e described as follows: 
Top of head dull brown; cervix the same, with greenish gloss, the 
feathers margined with ochraceous; back and rump metallic grass 
green, the feathers of the former narrowl}', of the latter broadly edged 
with bufly and ochraceous; upper tail-coverts ochraceous buff, more 
or less barred with dusky green; wings sepia, with a purplish sheen, 
the superior coverts green like the back; tail greenish on basal por- 
tion, terminall}' brownish black, broadly tipped with white, this last 
on the long central feathers amounting to much more than a third of 
their total length; superciliary and loral stripes deep buff; auriculars 
brownish black; throat and l>reast dull grayish, with a wash of ochra- 
ceous; a central gular and the rictal stripes buffy white; abdomen and 
crissum buffy white. 
Phoethornis longirrMrh haroni is very different from typical longi- 
7'ostris^ taking birds from Honduras as such, and, in fact, is nearer to 
Phoethornis Uwgrrostris mexicanu^ (Hartert). From the latter it may 
be distinguished by its decidedly smaller size {mexicanus is somewhat 
larger than the true longi7'Ostris), less bronzy upper parts, and the 
ver}'^ much less ochraceous lower surface. Specimens from Panama 
are, in size and color, somewhat intermediate between loiigirostris and 
haroni^ though certainly referable to the former. 
The following measurements exhibit the differences of size between 
PhodhovniR longirostris Jongh'ostrh and P. longirostris haroni:
