These references all pertain to a single occurrence, being the cap- 

 ture of an immature example at Bonda on October 22, 1898, by one of 

 Mr. Smith's collectors. To the list of South American records enu- 

 merated by Cooke Mr. Hellmayr has added two more, from Brazil 

 and Venezuela respectively. Being a bird of retiring habits, and not 

 to be considered common under any circumstances, even during migra- 

 tion, it is not strange that it has escaped observation in its winter 

 habitat. It is not yet clear whether it actually winters in this region 

 or is merely a transient during migration. 



421. Oporornis formosus (Wilson). 



Geothlypis formosa Bangs, Proc. Biol. Soc. Washington, XII, 1898, 144 



(" Santa Marta "). — Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 177 

 (Bonda). — Allen, Auk, XVII, 1900, 366 (Bonda; "Santa Marta," ex Bangs). 



— Cooke, Bull. Biol. Survey, No. 18, 1904, 108 (Santa Marta localities and 

 references) . 



Oporornis formosa Ridgway, Bull. U. S. Nat. Mus., No. 50, II, 1902, 622 

 (Santa Marta region, in range). 



Five specimens : Bonda and Don Diego. 



One of the rarer species, but, unlike O. Philadelphia, it seems to be 

 confined entirely to the lowlands. Mr. Smith's collectors secured no 

 less than nine specimens at Bonda, the earliest taken on October 7. 

 Mr. Brown got but one specimen on his entire trip. The single speci- 

 men taken at Don Diego by the writer was found on the shores of a 

 lagoon in the forest on January 28, 1914. These appear to be the 

 only South American winter records for the species. 



422. Dendroica striata (Forster). 



Dendroica striata Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 177 (Bonda). 

 — Allen, Auk, XVII, 1900, 366 (Bonda). — Cooke, Bull. Biol. Survey, No. 

 18, 1904, 76 (Bonda, Mamatoco, and Cautilito ; references). 



Twelve specimens : Bonda, Cautilito, Mamatoco, Punto Caiman, 

 Cincinnati, Dibulla, and Fundacion.
