Messrs. Bangs and Penard (Bulletin Museum of Comparative Zool- 

 ogy, LXIII, 1919, 28) have recently shown that the specific name 

 cineracea, heretofore in use for this form, has been misapplied, and 

 really belongs to a species of Myiochanes. They adopt instead the 

 name latirostris of Cabanis and Heine, based on the bird of Bolivia. 

 Specimens from that country in the collection of the Carnegie Museum 

 are obviously separable from the Colombian and Venezuelan birds by 

 their duller, browner general coloration, so that it has become neces- 

 sary to provide the northern birds with a new name. The differences 

 existing between S. latirostris and S. nigricans are such, in the judg- 

 ment of the writer, as to justify specific rank for both. The present 

 series includes several immature birds, in which the wing-coverts are 

 tipped with buffy instead of white. 



The range of this species lies within the Tropical Zone, extending 

 upward from sea-level to nearly 5,000 feet. It is of local distribution, 

 occurring wherever there are rapid streams. It seldom perches on 

 trees, keeping more to the rocks in the streams, like Serpopliaga 

 cincrca cana and ductus rivularis. The nest is usually built under 

 an overhanging rock at the edge of a stream, and is of the same type 

 of construction as that of S. phasbe of the eastern United States. The 

 eggs, according to Dr. Allen, are clear dull white, unspotted, and (in 

 the single set received) three in number. 



A most unusual nesting-site was observed by the writer in May, 

 1 919. In this case the nest was built under the roof of the veranda 

 in front of the main house at the hacienda Cincinnati, the nearest 

 stream being fully two hundred yards away. Later in the season the 

 birds built another nest on the back porch of the same building. The 

 species is thus beginning to imitate the Phcebe-bird of the north in its 

 selection of a nesting-site.
