* Genus Goethalsia Nelson: "Apparently nearest to Goldmania, the three or four 

 middle under tail coverts being shorter than usual and specialized as in that genus, 

 silky white in color and forming a tuft of overlapping or "nested" and strongly 

 decurved stiflE plumes about twice as long as in Goldmania and more plume-like 

 nearly to base of feathers; other under tail coverts normal and differently colored 

 from middle ones but proportionately smaller than usual; this strong character 

 present in both sexes and in the young as in Goldmania; primaries mediurn width, 

 broader than in Goldmania normal in all conditions (?) and outer primary distinctly 

 longer than next one; tail emarginate, nearly three-fifths the length of wing; bill 

 slightly broadened and ridged at base; terete elsewhere and same length as head; 

 nostrials operculate, feathering of forehead extending out about two-thirds of 

 length of nostrils; tarsus bare, except near upper end in front. Color: Males on 

 head and body mainly plain metallic green above and below except buflEy rufous mask 

 on chin and lores and buflfy whitish on posterior abdomen; primaries purplish black; 

 secondaries rufous dark tipped as in Eupherusa; tail feathers pale rufous buflfy with 

 exposed parts of middle feathers dark bronze green and same color on tips of other 

 feathers decreasing proportionately in width to a fine narrow margin on outer 

 feathers on each side." (Nelson, I.e.). 



^ Goethalsia bella Nelson: Male, top of head dull dark bronze green, shading to 

 brighter bronze green on neck and back and into golden bronze on rump; lores and 

 malar area dark reddish rufous, becoming reddish buff on chin; under parts from chin 

 to upper abdomen bright metallic green; crissum bufly and buflfy whitish, except 

 longer central under tail coverts, which are satiny- white, overlapping rigidly decurved 

 plumes as in Goldmani, but much longer and broader; sides of neck and body greenish 

 bronze; posterior flanks reddish buflfy; primaries purplish black; secondaries rusty 

 rufous tipped with bronzy purplish; tail mostly rusty buflfy, but exposed parts of two 

 middle feathers dark bronze green and lateral feathers tipped with proportionally 

 decreasing amounts of same to a narrow edging on tip of outer feathers on each side. 

 Wing, 52; tail, 29; culmen, 17 mm.
