ee BANGS — PANAMA BIRDS 29 
The cotypes are two adults, both males, in fine condition, nos. 
2848 and 2849, from Yuracares, Bolivia. 
Without doubt they represent a different form from the common 
species of Colombia and Central America. &. crassirostris is 
glossed on head and hind neck with purple, which gradually 
becomes steel blue on lower back and rump. The cotypes of 
£. lanitrostris are wholly glossed with purple above; below they 
are deeper yellow—more orange. J. /anitrostris is also larger 
(no. 2848, adult g, cotype: wing, 65.; no. 2849, adult ¢, 
cotype: wing, 66.5), and has a heavier, stouter bill. In &. eras- 
strostris the wing, in the adult male, measures about 62 mm., a 
large number of examples that I measured varying but little from 
this, either one way or the other. 
Eucometis cristata (Du Bus). 
Five specimens, both sexes. A female taken March 25 had an 
egg in the oviduct. 
Mitrospingus cassini (Lawr.). 
Two specimens, a pair, taken March 27. 
Heterospingus rubrifrons Lawr. 
One male. 
Tachyphonus rufus Bodd. 
Twenty-seven specimens, both sexes. 
Tachyphonus luctuosus Lafr.
