Hab. Jalapa and Cordova, Mexico. 



Male. A little larger in size than the C. pulclira, but in the color of its plumage 

 almost precisely like that species. It can always be distinguished by the outermost 

 rectrices, which are filiform in shape, almost denuded of webs and pointed. Total 

 length, 3,^ in. Wing, \ in. Tail, 1| in. Culmen, f in. 



Female like that of C. jnilchra, except the tail, which has the lateral feathers 

 greenish at base instead of buff, then black and tipped with white. Bill black. 

 Total length, 3 in. Wing, 1§ in. Tail, 1.^ in. Culmen, f in. 



The members of the next genus Acestrura are even smaller than those of the 

 last, and the males have equally brilliant throats. Their tails are very singular, 

 the two outermost rectrices being filamentous, the shafts having hardly any webs 

 attached; the one next to these is the longest, rather broad at base and pointed at 

 tip; and the two middle ones are very short, projecting but a short distance beyond 

 the coverts. The tail of the female is entirely different, being rounded and tlie 

 feathers rather broad and even.
