Boquete, with 1 record for 1,600 meters at Velo, above the Finca 

 Lerida, and another at 2,200 meters above Cerro Punta; recorded 

 east to southwestern Veraguas. 



On June 8, 1953, I saw 2 on the Rio Vidal below Puerto Vidal, 

 western Veraguas, a point approximately 5 kilometers from the 

 boundary with Chiriqui. Griscom and Boulton collected a female on 

 the lower Rio San Lorenzo west of Punta Brava in southern Veraguas, 

 April 8, 1924. 



The first record for the Republic was published by Lawrence (Ann. 

 Lye. Nat. Hist. New York, vol. 8, Nov., 1865, p. 179) under the name 

 Pteroglossus erythropygius, based on a female in the Smithsonian col- 

 lection taken by Fred Hicks at David, Chiriqui, in February 1865. 

 Salvin (Proc. Zool. Soc. London, 1870, p. 211) identified it correctly 

 as frantzii from specimens (now in the British Museum) collected 

 in 1869 by Arce at Bugaba. Bangs (Auk, 1901, p. 360; Proc. New 

 England Zool. Club, 1902, p. 32) added further records from birds
