Descriptions of New Species of Birds. 43 



Remarks. — Obtained by Mr. Alexis A. Julien, in compli- 

 ment to whom I have named it. 



Differs from the other yellow-billed West India species, in 

 being without any rufous coloring below or on the quills. 



Fam. TROCHILID.E. 

 5. Urochroa leucura, nov. sp. 



Upper plumage shining grass green, becoming coppery-bronze on the 

 rump and upper tail-coverts ; two central tail feathers dull bronzy green, 

 blackish purple at the end, the four other feathers on each side white, 

 the outer feather margined broadly and the other feathers narrowly on 

 the outer webs, with dull black, and a narrow edging of the same color 

 near the end on the inner webs of the three outer ones, but a broader 

 margin on that of the feather next the central ; wings brownish purple ; 

 throat brilliant dark blue ; chin, sides of the neck, breast, and sides of 

 the abdomen shining green ; middle of abdomen dull dark ash ; under 

 tail-coverts bronzed coppery olive ; bill and feet black. 



Length 5^ inches; wing 2§ ; tail If; bill 1 T 3 F . 



Habitat. — Ecuador. 



Remarks. — This is closely allied to U. Bougueri (Bourc). 

 It may possibly be that species, and it is with some hesitation 

 that I venture to describe it as distinct ; there are some differ- 

 ences, however, of color and markings which I cannot reconcile. 



Mr. Gould, in Monog. Troch. (where a fine figure of TJ. Bou- 

 gueri is given) describes that species as having the sides of the 

 head and the upper plumage of a dark coppery bronze, becom- 

 ing brighter or more coppery on the upper tail-coverts. In the 

 present bird, with the exception of a very slight tinge on the 

 crown, the rump and upper tail-coverts only are coppery, the 

 rest of the upper plumage being green. The two species differ 

 materially in the color of the tail. Mr. Gould states that U. 

 Bougueri has " the two centre and the outer tail feather on 

 each side purplish black ; the remaining tail-feathers white,
