148 New Species of Birds from St. Vincent, 



Types in National Museum, "Washington. 



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 M. genibarbis, but it is more defined. 



M. armillatus (according to the description and plate) 

 differs in being of a lighter color above, slate-gray (gris 

 ardoise) ; in having the red of the under plumage darker, 

 brownish-red (brun 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 natural- 

 ists and visitors to the mountains, that it is called the ' invisible 

 bird.' From being seen only on the Souffriere Mountain, it 

 has acquired the name of the 'Souffriere bird.' " 



Mr. Ober is entitled to great credit for unravelling the 

 mystery connected with this bird. By his indomitable perse- 

 verance, and camping out on the top of the mountain for 

 several days, he secured seven specimens.
