 " iris bright hazel." 



Length (fresh), j\ in. ; wing, 3f ; tail, 3 ; tarsus, I. 



The sexes do not differ in plumage. 



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. geni- 

 barbis, 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 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 

 * Soufriere-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.
