The two sexes of this bu-d were first brought to the notice of Ornithologists in 1845, 
by the late Baron de Lafresuaye in a paper published in the " Revue Zoologique," in which 
he names them both as separate and distinct species, callmg the male bird Micropogon 
Bourcieri, and the female C. HarUauU. This error remained undetected until the present 
year when it was discovered by Mr. Osbert Salvui, and recorded by hun in a recent paper 
in the " Ibis," where, in a critique upon Mr. Lawrence's list of the birds of Costa Rica, 
draws attention to the fact in the following words: — 
" It has long struck me as singular that these two supposed species should always be 
" found together. Upon examination of all the specimens that, had the sexes marked, I 
" found that all the C. Bourcieri were males, and all the C. Hartlauhi females. In a small 
" collection from Ecuador obtained from Mr. Gould, I found a specimen with the head tinged 
" with golden yellow, just as in C. Hartlauhi., while the forehead and throat as well as a few 
" feathers on the sides of the occiput were red. In fact, this specimen, a young male, was 
" shot while it was putting off the Hartlauhi., and assuming the male or Bourcieri plumage ; 
" this transitional state convinced me that the sexes of one species had hitherto been 
" reo-arded as distinct.''
