and 1929 at Changuinola, Guabo, Almirante, and Cricamola (Peters, 

 Bull. Mus. Comp. Zool., vol. 71, 1931, p. 340). There are also several 

 old records from other provinces: Arce collected it in Chiriqui at Buga- 

 ba and Volcan de Chiriqui (Salvin, Proc. Zool. Soc. London, 1870, p. 

 186). A pair taken by McLeannan and Galbraith on the Caribbean 

 slope near the Panama Railroad was reported by Lawrence (Ann. Lyc. 

 Nat. Hist. New York, vol. 7, 1861, p. 332). The male could hardly be 

 misidentified, if adult, but there is a female in the Smithsonian collec- 

 tions taken by McLeannan that had been identified as E. gouldi, but 

 which is actually referable to E. fulvicrissa. Thus it is unlikely that E. 

 gouldi praetermissa extends as far east as the Canal Zone. This race 

 ranges along the Caribbean slope north to extreme eastern Honduras; 

 the nominate form is found north to southeastern Mexico. 



This species differs from all other Panamanian euphonias in that the 

 male lacks the yellow and dark blue plumage that generally charac- 

 terizes the group. It inhabits forest, forest edges, and clearings, where 

 it forages at all heights. It usually moves about in pairs or small groups, 

 sometimes joining other species, such as flocks of Myrmotherula ant- 

 wrens. One that I collected on the bank of the Western River at Al- 

 mirante had the throat and gut filled with bright red plant juice that I 

 could not identify, as there were no seeds. The stomach was mem- 

 branous, like that of other euphonias I have examined. I have always 

 found this to be a quiet and inconspicuous bird, but Slud (Bull. Amer. 

 Mus. Nat. Hist., vol. 128, 1964, p. 349) records a variety of trills, 

 chirps, whistles, and other notes from both sexes. In Ridgely's ex- 

 perience, these notes are delivered very softly. On February 5 and 12, 

 1958, I took breeding males in Almirante, but I have no details from 

 Panama of their nesting habits. S. M. Russell (A.O.U. Monogr. no. 1, 

 1964, p. 168) found the nest of the nominate race in British Honduras. 

 It was domed and suspended from the tip of a branch about 2 m above 

 the forest floor. It contained no eggs. 



A male E. gouldi collected in Panama by Strauch (Bull. Brit. Orn. 

 Club, 1977, p. 65) weighed 10.9 g.
