ously around to the Goajira Peninsula, and has even worked west 

 along the coastal plain in small numbers as far as Dibulla. It was 

 abundant around Rio Hacha in the more open parts of the scrub 

 growth. 



312. Capsiempis flaveola leucophrys von Berlepsch. 

 Four specimens : Fundacion. 



There is an authentic skin of this form, received from von Ber- 

 lepsch himself, in the collection of the U. S. National Museum, with 

 which the above have been compared, and found to agree very closely, 

 although none of them are quite so white on the chin. The form is 

 sufficiently well characterized, but is clearly conspecific with C. 

 flaveola flaveola, while the Central American bird should stand as C. 

 flaveola semiflava (Lawrence). 



Four specimens were taken at Fundacion in October, 191 5, all in 

 open woodland, rather low down among the shrubbery or in open places 

 in the forest. It is a restless bird, feeding more like a vireo than a 

 flycatcher.

Five specimens : La Tigrera, Mamatoco, Fundacion, and Tucur- 

 inca. 



With a series of eleven skins now available, it is evident that not 

 all of the characters given in the original diagnosis of this form hold 

 good. The type happens to have an unusually dark cap, nearly all the 

 others having the pileum paler; in fact, this is a character which 

 varies unduly in all the forms of this species, and no dependence can 

 be placed on it. The series averages lighter green above if anything 

 than true amaurocephalus, but the difference here is very slight. The 

 Santa Marta bird is a pale littoral race, distinguishable from both ■ 

 amaurocephalus and faustus by the lighter and more uniform colora- 

 tion of the under surface. Specimens from the interior of Colombia 

 are decidedly more richly colored, and are clearly referable to a dif- 

 ferent race, which is probably peruvianus of Sclater and Salvin. The
