Rhamphocoelus [sic] dunstalli Rothschild

Rhamphocoelus [sic] dunstalli Rothschild, 1895: 481 (Central America and probably Panama).

Now Ramphocelus dimidiatus × R. icteronotus . See Hartert, 1919: 149, Griscom, 1932a, Hellmayr, 1936: 261–264, Olson and Violani, 1995: 304– 305, and Dickinson, 2003: 806.

HOLOTYPE: AMNH 510004 , unsexed [male], locality unknown, purchased from K. Dunstall. From the Rothschild Collection.

COMMENTS: When this bird was described, Rothschild had the single specimen; he commented: ‘‘By the make of the skin it evidently came from Central America , and probably Panama.’’ Hartert (1919: 149) commented that later Rothschild had purchased a second similar specimen from Comte de Dalmas, who in 1896 had bought it from Sciama, a feather-dealer in Paris. This second specimen has no type standing .

Griscom (1932a) came to the conclusion that R. dunstalli was a hybrid between R. dimidiatus and R. icteronotus , and Olson and Violani (1995: 304–305) agreed with this assesment. Hellmayr (1936, 263, footnote) disagreed and thought that it was merely a ‘‘freaky’’ mutation of R. passerinii .
