458 Descriptions of Six New Species of Birds. 



4. Trocliilus auVi^ularis. 



Male. Upper plumage shining green, on the head, hind neck, and 

 upper part of the back, of a bronzed or coppery shade ; two central tail- 

 feathers of a rather dull bronzed green, the other tail-feathers brownish- 

 purple ; wings brownish-purple; chin black, throat brilliant metallic 

 golden green, on the upper part and lengthened lateral feathers of the 

 gorget the color is deep orange, and on the tips of some of the feathers 

 intensified to brilliant red ; below the gorget is a whitish band becoming 

 ashy-grey on the breast, which is also the color of the abdomen and 

 sides, the latter washed with dull green ; the bill is pale yellow ; feet 

 light brown, claws yellowish-white. 



Length 3f in.; wing 1|; tail 1^; bill f.

 others, all have the chin black, with a brilliant gorget succeeded 

 by a band of whitish feathers, and ashy under plumage. 



The above specimen was in spirits, which, perhaps, has 

 deepened the colors somewhat, but I think they liave not 

 changed materially. 



This species Avas also sent from the Smithsonian Institution 

 for examination ; it was in a bottle by itself without collector's 

 name or locality being given, and Prof. Baird did not know 

 whence it came. 



5, l^appliironia luminosa. 



Upper plumage glittering grass-green, inclining to golden on the 

 rump, the crown not so bright and of a very deep green ; entire under 

 surface of a very brilliant bluish green, the sides of the neck golden 

 orange ; tail forked and of a rich steel blue, the two middle feathers
