chill and throat indistinctly streaked with dingy whitish and dusky, 

 wliile the jugnhmi and entire sides are dark shite, very much darker 

 than in the other suecimens, only the centre of the abdomen being 

 "whitish. Some of the feathers of the breast show indistinct whitish 

 shaft-streaks, while the entire under surface is pervaded by a greater 

 or less amount of fuliginous wash. The entire upper parts are a per- 

 fectly uniform bhick, the other specimens having a decidedly shite-col- 

 ored cast. The bill and feet of this siiecimen still retain their brilliant 

 hue, the entire mandible and edges of the maxilla being an intense 

 orange-red, while the legs and feet are a deep orange-yellow color. The 

 collector's notes ujion the label are as follows : " Iris white ; bill orange- 

 red, with upper mandible black; tarsi and feet orange- yellow". 



This specimen was obtained at Cuscua, La Palma, September 25, 

 1881, by Mr. Juan Cooper.

A single specimen from Carrillos, Alajuela (October, 1879; Juan

Sp. ch. — Above bright tawny-brown, duller posteriorly, the forehead
