REMARKS. This differs from all the West India species in its 
black upper plumage. The color of the throat is much lighter than 
in M. genibarbis and solitarius» in both of these the color is of a 
deep chestnut red ; it has the black moustachial line as in AZ. genz- 
barbis, but it is more defined. 
M. armillatus (according to the description and plate) differs in 
being of a lighter color above, slate-gray (gvzs ardozise); in having 
the red of the under plumage darker, brownish-red (druz roux) ; it 
has no moustachial line, and the eye is encircled with white ; but it 
varies especially in having the feathers of the thigh terminating in 
bright yellow. 
Mr. Ober writes : “ This bird has been an object of search for fifty 
years, and has so long eluded the vigilance of naturalists and visitors 
to the mountains, that it is called the ‘invisible bird.’ From being 
seen only on the Soufriere Mountain, it has acquired the name of 
‘ Soufriére-bird.’ ” 
Mr. Ober is entitled to great credit for unraveling the mystery 
connected with this bird. By his indomitable perseverance, and 
camping out on the top of the mountain for several days, he secured 
seven specimens.
