consequently large whitish throat area, which is buffy in the female and more 

 or less washed with bufPy in the male, and by its longer bill.

Galbula melanogenia Scl., Contr. Orn., 1852, p. 61, pi. 90 (Vera Paz, Guate- 

 mala?); Hellm., p. Z. S., 1911, p. 1194 (Rio Cajon; El Tigre; juntas). 



Inhabits the Tropical Zone of the Pacific coast. Eighteen specimens 

 from this region agree with a series from Ecuador and are somewhat smaller 

 and with the rufous areas darker than in twenty-one specimens from Mexico, 

 Nicaragua and Chiriqui. Accepting Vera Paz, Guatemala, whence Sclater 

 believed his type came {cf. Mon. Jacanas and Puff -Birds, p. 19) as the type- 

 locality for melanogenia, it might be considered advisable to separate the 

 Colombian and Ecuadorian form; but, in my opinion, the differences be- 

 tween even the extremes of the series are too slight to warrant this course.

Inhabits the Tropical Zone at the eastern base of the eastern Andes. 

 Twelve specimens from Villavicencio and Buena Vista (whence doubtless 

 come Bogota specimens) have the chin somewhat whiter, the abdomen 

 slightly paler than three specimens from La Morelia. I have no topotypi- 

 cal specimens. The female has the abdomen conspicuously paler'than in 

 the male.

 Galbula chalcocephala Dev., Rev. at Mag. de Zool., 1849, p. 55 (Sarayacu, Ecuador) . 



Five specimens from La Morelia agree with three from eastern Ecuador 

 and are readily distinguished from twelve from Guiana (true albirostris) by 

 their darker underparts, blacker chin, more purple-bronze crown and 

 wholly black (or nearly so) maxilla.
