FAMILY PIPRIDAE 325 



Tacarcuna, March 6, 1964, was similar, except that the maxilla and 

 tip of mandible were black, with the base of the mandible dull neutral 

 gray. 



Resident. Found locally in Tropical Zone forests in eastern Darien 

 and eastern San Bias. 



Though Chapman (Bull. Amer. Mus. Nat. Hist., vol. 55, 1926, 

 p. 555) in writing of this bird in Ecuador listed it as ranging to 

 "eastern Panama" he does not give the basis for this statement. The 

 first specimen record for Panama is by Griscom (Bull. Mus. Comp. 

 Zool., vol. 69, 1929, p. 178) of a male taken by Benson at Cana, on 

 Cerro Pirre, March 22, 1928. When Hasso von Wedel forwarded 

 two additional males from Ranchon and Puerto Obaldia, San Bias, 

 Griscom (cit. supra) described the bird of Panama as a distinct sub- 

 species, C. h. siiffusa. Feinstein collected a male at the old village 

 site on the upper Rio Tacarcuna, February 11, 1959. Galindo secured 

 a male there June 24, 1963, and I obtained another March 6, 1964. 

 Others were taken by Galindo at La Laguna, and by me on the 

 north fork of the upper Rio Pucro, higher on the slopes of Cerro 

 Tacarcuna, at 1250 meters. Galindo also collected a male February 28, 

 1971, at 730 meters on Cerro Quia. The recent specimens were 

 captured in mist nets set in undergrowth. 



The series now available from Panama compared to specimens of 

 litae from southern Narifio, Colombia, show no differences, so that the 

 proposed race suffusa for Panama is not recognized.
