 darker brown in the middle, then crossed by a lunate mark of ful- 

 vous, to which succeeds an irregular mark of black, and terminated 

 with fulvous ; under surface paler than the upper, caused by each 

 feather being crossed by three rays of fulvous instead of two, and 

 more largely tipped with that colour ; the feathers of the thighs re- 

 semble those of the back ; bill dull yellowish horn- colour ; feet and 

 claws fleshy-brown.

 John Gould, Esq., F.R.S. (continued*), with the charac- 

 ters OF TWO NEW GENERA AND DESCRIPTIONS OF THREE NEW 

 SPECIES. 



Metallura, gen. nov. 

 Char. gen. — Rostrum rectum, sublongum. Plumes molles sericeae. 



Cauda subgrandis, rotundata. Gula et rectrices infra tanquam 



metallum expolitum luminosae. Alee subgrandes. Tarsi nudi. 



Pedes subgrandes. Digitus et unguis postici digitum et unguem 



medios longitudine sequantes vel superantes. 



Gen. char. — Bill straight, moderately long ; plumage soft and silky ; 

 tail rather large and rounded ; throat and under surface of the tail- 

 feathers very luminous, like shining metal ; wings moderately large 

 and apparently adapted for an easy mode of flight ; tarsi bare ; feet 

 rather large ; hind- toe and nail as long or longer than the middle 

 toe and nail. 



Females. — Much less brilliant than the males in every respect, and 

 in most of the species wanting the luminous mark on the throat. 



The species are — 



Trochilus cupreocauda, Gould. 



Trochilus aneocauda, Gould. 



Trochilus Alardi, Bourc. 



Trochilus smaragdinicollis, D'Orb. 



Trochilus WiUiami, Bourc. 



Doryfera, gen. nov. 



Char. gen. — Rostrum forte, ad tertiam partem apical em, quae sursum 

 curvatur, rectum. Ala subgrandes. Cauda rotundata, subrigida, 

 rectricibus singulis mucronatis. Tarsi aliqua parte vestiti. Pedes 

 magnitudine mediocri. Digitus et unguis postico digito et ungui 

 medio longitudine sequales. 

 Gen. char. — Bill long, straight for three-fourths of its length, and
