This seems to be among the very smallest members of this group 

 of birds ; it certainly is of the genus to which it belongs. It is 

 readily recognized by the vivid green of the upper parts, and the 

 brown head and neck, these last parts giving the bird the appearance 

 of not being adult. A specimen in Messrs. Salvin and Godman's 

 collection was brought from the Straits of Magellan by Capt. King, 

 thus extending the range beyond that given by Mr. Ridgway, viz. 

 quite to the end of the South-American continent. 



Head and neck and underparts dark rufous brown, with some 

 slight greenish reflections upon the flanks. "Wings and upper parts 

 and tail brilliant grass-green. Throat and cheeks light-brown, 

 streaked with five white marks. Bare skin between the eye and 

 bill, partly surrounding the former, apparently red. Bill reddish 

 orange. Legs and feet dark red. Total length without bill 13^ 

 inches ; wing 9, tail 4j, bill along culmen 3\, tarsus 3.

This species is extremely rare ; and I know of only three or four 

 specimens, the majority of the museums in Europe not having it re- 

 presented in their collections. It is very distinct from all other 

 known species, and, like many of its relatives, belongs apparently to 

 a genus diflPerent from any yet instituted, and is placed best between 

 the Falcinellus and Eudocimus. I propose for it the term Lampribis, 

 with the following characters : — 



Space around and behind the eye, extending backwards to a point, 

 and entire base of mandibles bare of feathers ; the feathers of the 

 throat reaching between the crura of mandible. Culmen on its basal
