 Diego, Pueblo Viejo, Chirua, and Heights of Chirua. 



The peculiarities of Santa Marta examples of P. longirostris were 

 not detected until the acquisition of a good series from that region, 

 collected by Mr. Brown, enabled Mr. Bangs to point them out and dis- 

 criminate the bird as a new subspecies. The characters he assigns hold 

 good in the present fine series, which is decidedly more buffy below 

 than a series of the Costa Rican form. So far as known P. longiros- 

 tris susurrus is confined to the Santa Marta region, where it ranges 

 over the north and northeast slopes of the San Lorenzo and Sierra 

 Nevada between 2,000 and 5,000 feet, the latter altitude being based 

 on a record from the Heights of Chirua. Its area of greatest abun*- 

 dance, according to the experience of the writer, is lower down in the 

 Sierra Nevada than on the San Lorenzo. Two specimens were even 

 taken at Don Diego, on the north coast. It is more addicted to tangled 

 woodland and the fringes of trees and shrubbery along streams, al- 

 though found in the heavy forest as well, and is usually seen low 

 down. During the breeding season the males are almost continually 

 singing their quaint little chirping song of two or three notes. At 

 such times they conceal themselves in a tangle of vines or shrubbery, 

 open their bills widely, twist their heads about and twitch their tails 

 up and down in a perfect ecstacy of song.
