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 oi Heliomaster pallidiceps^^, 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 Duenas. Here it is rather a rare bird, though every now and then we 

 secured a specimen when feeding from the flowers of Ipomcea murucoides. In the 

 State of Panama this species seems to be very abundant, as our collector Arce 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 Heliorrmster stewartoe, and Cabanis and Heine described the Venezuela bird as 

 H. sclateri. 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.
