1— Sporadinus Bracei. 



Male. Crown and gorget of a glittering pale green ; back, upper tail- 

 coverts, the two central and the next pair of tail-feathers, bronzed golden- 

 green ; the other tail-feathers are purplish-black, with their outer edges 

 bronzed green ; quills blackish-purple ; breast and abdomen dull bronzy- 

 green; under tail-coverts dark ash bordered with white; bill and feet 

 black. 



Length, 3$ in. ; wing, If ; tail, 1£ ; bill, f. 



Type in National Museum, Washington. 



Habitat : Island of New Providence, Bahamas. 



Remarks. The specimen is a mummy, and the outer two 

 tail feathers are just being renewed, the length of these is 

 important to determine its true generic position ; but as it re- 

 sembles Sporadinus Ricordii in other respects, I place it pro- 

 visionally in the same genus. If the outer tail feathers were 

 fully developed, they would doubtless increase the total length, 

 as well as that of the tail. This species is nearly allied to S. 

 Ricordii from Cuba, but differs from it in being smaller, with 

 a longer bill ; the green of the crown and throat is paler and 

 more of a steely shade ; the back is more bronzed, and the 

 under plumage of a lighter green. 



I have named this species in honor of L. J. K. Brace, Esq., 

 who is now investigating the ornithology of New Providence, 

 and recently sent this species, with a few others, to the Smith- 

 sonian Institution. 



2 — Orthorhynchus emigrans. 



Male. The basal half of the crest is of a shining emerald-green, the 

 terminal half deep reddish- violet ; the upper plumage is dark grass-green ; 

 tail-feathers blackish-purple, the two central ones washed with green; 

 quills light purple ; throat smoky-gray ; breast and abdomen smoky-black ; 

 bill and feet black.
