Males of this species from Guiana and Venezuela have rather bluer heads than those 
from Mexico, Panama birds being nearly intermediate. The northern bird was separated 
by Gould under the name of Heliomaster pallidiceps 8, but with the series now before 
us we do not see our way to admitting any specific difference. 
Floricola longirostris is not a common bird in Mexico, and does not seem to be 
found northward of Jalapa in the State of Vera Cruz. It is absent from Western 
Mexico, but occurs on the Isthmus of Tehuantepec, and thence southwards on both 
sides of the Cordillera of Guatemala, reaching an altitude of nearly 5000 feet in the 
mountains near Duefias. Here it is rather a rare bird, though every now and then we 
secured a specimen when feeding from the flowers of Ipomwa murucoides. In the 
State of Panama this species seems to be very abundant, as our collector Arcé obtained 
us many specimens, finding it in nearly every place he visited. It is equally common 
in the parts of South America in which it is found. | 
Other attempts to divide the Central-American birds besides that of Gould have 
been made; Mr. Lawrence referred the Panama form to that of Colombia, which 
he called Heliomaster stewarte, and Cabanis and Heine described the Venezuela bird as 
H. sclatert. In our opinion both birds belong to F. longirostris. The trifling paler 
shade of the crown, being variable in itself, is insufficient for definition, and other 
characters, such as the width of the bill, are equally untrustworthy.
